They are primarily intended for the non-PoE AT-x930-28GTX, AT-x930-28GSTX, and AT- x930-52GTX Switches. The AT-x930- 28GTX and AT-x930-28GSTX Power Supplies have AC connectors. The AT-PWR250-80 Power Supply has a DC connector for DC wiring environments.

Figure 6. AT-PWR150, AT-PWR250, and AT-PWR250-80 Power Supplies
Here are the operating characteristics:

• The power supplies provide system power only. They do not support PoE+ devices.
• A single power supply can power an entire switch.
• Installing two power supplies adds power redundancy.
• The power supplies are not recommended for the PoE+ AT-x93028GPX and AT-x930-52GPX Switches because they do not supply power for PoE+ devices. You may install them into PoE+ switches, but the switches will not support powered devices.

System and PoE+ Power Supplies
The AT-PWR800 and AT-PWR1200 Power Supplies provide both system power and power for PoE+ devices on AT-x930-28GPX and AT-x93052GPX Switches. Refer to Figure 7.

A PoE+ switch with one AT-PWR800 Power Supply has the following power characteristics:

• Full system power
• 380 watts of PoE+ power

A PoE+ switch with two AT-PWR800 Power Supplies has these power characteristics:

• Full system power and redundant system power
• Either 740 watts of PoE+ power or 380 watts of active PoE+ power and 380 watts of redundant PoE+ power.

A PoE+ switch with one AT-PWR1200 Power Supply has the following power characteristics:

• Full system power
• 740 watts of power for PoE devices

A PoE+switch with two AT-PWR1200 Power Supplies has these power characteristics:

• Full system power and redundant system power
• Either 1440 watts of PoE power or 740 watts of active PoE power and 740 watts of redundant PoE power.

Guidelines
Please review the following guidelines concerning power supplies:

• The x930 Series Switches do not come with power supplies. Power supplies must be ordered separately.

• If you install two power supplies in the switch, they must both be the same model. For example, you may install two AT-PWR800 Power Supplies or two AT-PWR1200 Power Supplies in a switch.
  You may not install two different power supply models in the switch.

• The non-PoE AT-x930-28GTX, AT-x930-28GSTX,and AT-x93052GTX Switches require only one power supply for full operations.
  Installing a second power supply adds power redundancy,  which protects against interruptions to network operations in the event a power supply loses power or fails.
  Power redundancy is available only when both AC  or DC connectors on the switch are connected to power sources.

• The PoE AT-x930-28GPX and AT-x930-52GPX Switches also require only one power supply for network operations, excluding PoE+. The switches can continue to operate even if one power supply fails or loses power. Adding a second power supply in the  PoE+ switches either increases the amount of power for powered devices or adds PoE+ redundancy. For further information, refer to “Power Budget” on page 34.

• You may install AT-PWR800 and AT-PWR1200 Power Supplies in non-PoE x930 Switches. The power supplies will provide system power only.

• The DC wires for the AT-PWR250-80 DC Power Supply should be routed from a DC load center containing appropriate overcurrent branch protection for each DC feed, as required by the cognizant local electrical authority.

Refer to “Technical Specifications” on page 203 for the input voltage ranges.

Warning
Power cord is used as a disconnection device. To de-energize equipment, disconnect the power cord. E3

Warning
This unit might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before servicing the unit. E30

Note
The AT-PWR150, AT-PWR250, AT-PWR800, and AT-PWR1200 Power Supplies are powered on or off by connecting or disconnecting the power cords. The AT-PWR250-80 Power Supply is powered on or off with its On/Off power switch or by deactivating the  DC circuit.

10/100/1000Base-T Copper Ports
The copper ports on the switches are described in this section.
Speed
The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set manually using the management software or automatically with AutoNegotiation (IEEE 802.3u), the default setting.
Note
The ports must be set to Auto-Negotiation to function at 1000 Mbps and are not compatible with devices that are not IEEE 802.3u compliant.

Duplex Mode
The copper ports can operate in either half- or full-duplex mode. The duplex mode of a port, like port speed, may be set manually using the management software or automatically with Auto-Negotiation (IEEE 802.3u), the default setting.
The speed and duplex mode settings of a port may be set independently of each other. For example, a port may be configured such that its speed is set manually while its duplex mode is established through AutoNegotiation.

Note
A switch port should not use Auto-Negotiation to set its duplex mode if it is connected to a network device that does not support AutoNegotiation for 10 or 100 Mbps operation and has a fixed duplex mode of full-duplex. Otherwise, a duplex-mode mismatch may occur in which a switch port and a network device operate at different duplex modes. The duplex modes of switch ports that are connected to network devices that do not support Auto-Negotiation should be set manually through the management  software.

Wiring Configuration
The wiring configuration of a port operating at 10 or 100 Mbps can be MDI or MDI-X. The wiring configurations of a switch port and a network device connected with straight-through copper cabling have to be opposite, such that one device is using MDI and the  other MDI-X. For instance, a switch port has to be set to MDI-X if it is connected to a network device set to MDI.
You may set the wiring configurations of the ports manually or let the switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3abcompliant). This feature enables the switch to automatically negotiate with network devices to establish their proper settings.

The MDI and MDI-X settings do not apply when ports are operating at 1000 Mbps.

Maximum Distance
The ports have a maximum operating distance of 100 meters (328 feet).

Cable Requirements
Here are the cable requirements:

• 10 or 100Mbps – Standard TIA/EIA 568-B-compliant Category 3 unshielded cabling
• 1000Mbps – Standard TIA/EIA 568-A-compliant Category 5 or TIA/ EIA 568-B-compliant Enhanced Category 5 (Cat 5e) unshielded cabling.
  Note
  For the cable requirements for the ports on the AT-x930-28GPX and AT-x930-52GPX Switches for PoE devices, refer to “Cable Requirements” on page

Port Pinouts
Refer to Table 35 on page 210 and Table 36 on page 210 for the port pinouts of the 10/100/1000Base-T copper ports.

Power Over Ethernet
The AT-x930-28GPX and AT-x930-52GPX Switches feature Power over Ethernet (PoE) on the 10/100/1000Base-T ports. PoE is used to supply power to network devices over the same copper cables that carry the network traffic.
The main advantage of PoE is that it can make it easier to install a network. The selection of a location for a network device is often limited by whether there is a power source nearby. This often limits equipment placement or requires the added time and cost of having additional electrical sources installed. But with PoE, you can install PoE-compatible devices wherever they are needed without having to worry about whether there are power sources nearby.
A device that provides PoE to other network devices is referred to as power sourcing equipment (PSE). The AT-x930-28GPX and AT-x93052GPX Switches act as PSE units by adding DC power to the network cable, thus functioning as a central power source for  other network devices.

Devices that receive their power from a PSE are called powered devices (PD). Examples include wireless access points, IP telephones, webcams, and even other Ethernet switches.
The switch automatically determines whether or not a device connected to a port is a powered device. Ports that are connected to network nodes that are not powered devices (that is, devices that receive their power from another power source) function as  regular Ethernet ports, without PoE.
The PoE feature remains activated on the ports but no power is delivered to the devices.

PoE Standards
The AT-x930-28GPX and AT-x930-52GPX Switches support these PoE standards:

• PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the switch port to support powered devices that require up to 12.95 watts.
• PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at the switch port to support powered devices that require up to 25.5 watts.

Powered Device Classes
Powered devices are grouped into the five classes listed in Table 2 on page 34. The classes are based on the amount of power the devices require. The switches support all five classes.

Table 2. IEEE Powered Device Classes

Power Budget
The power budget defines the maximum amount of power the switch can supply to the powered devices on its ports. The higher the budget, the more PoE devices the switch can support at one time.
The power budgets for the AT-x930-28GPX and AT-x930-52GPX Switches depend on several factors. The first is the power supply model.
The power budgets of the five power supplies are listed in Table 3.

Table 3. Power Supply Budgets of the Power Supplies

Note
The AT-PWR150, AT-PWR250 and AT-PWR250-80 Power Supplies are intended for the non-PoE AT-x930-28GTX, AT-x93028GSTX, and AT-x930-52GTX Switches. They are not intended for the AT-x930-28GPX and AT-x930-52GPX Switches because they do not provide power for PoE + devices. You may install them in the PoE+ switches, but the switches will not support PoE devices.

Another factor that determines the power budget of the switch is the number of PoE power supplies in the device. The power budget of a PoE switch that has only one PoE power supply is equal to the budget of the power supply. For example, a switch that has  one AT-PWR1200 Power Supply has a power budget of 740W for powered devices.

A PoE switch with two AT-PWR800 or AT-PWR1200 Power Supplies has either redundant PoE power or nearly double the power budget. This is controlled by the power boost feature, which has a status of either enabled or disabled. When the power boost  feature is enabled, a PoE switch with two power supplies actively uses the PoE power from both supplies to increase its available power budget. When the feature is disabled, the switch uses the PoE power of only one of its power supplies and keeps the other in  reserve in case the primary power supply should fail or lose power. The default setting of power boost is disabled.
As an example, assume that a PoE switch has one AT-PWR1200 Power Supply, which has a power budget of 740W for powered devices. Thus, the switch would have a total power budget of 740W. Now assume the switch has two AT-PWR1200 Power Supplies.  When the power boost mode is enabled, the switch uses the PoE power from both supplies, for a total power budget of 1440W. When the power boost mode is disabled, the switch has an active PoE power of 740W and a redundant budget of the same amount.  The switch activates the redundant power budget only if the power supply providing the active power budget fails or loses power.

Table 4 lists the power budgets for the switch with one or two AT-PWR800 Power Supplies and the power boost mode.
Table 4. Power Budgets of the AT-PWR800 Power Supply

Number of Power Supplies in  the Switch| State of Power Boost| Power Budget of the Switch| Redundant Power
---|---|---|---
One| NA| 380 watts| 0 watts
Two| Enabled| 740 watts| 0 watts
Two| Disabled| 380 watts| 380 watts

Table 5 lists the power budgets for the switch with one or two ATPWR1200 Power Supplies and the power boost mode.
Table 5. Power Budgets of the AT-PWR1200 Power Supply

Number of Power Supplies in  the Switch| State of PowerBoost| Power Budget of the Switch| Redundant Power
---|---|---|---
One| NA| 740 watts| 0 watts
Two| Enabled| 1440 watts| 0 watts
Two| Disabled| 740 watts| 740 watts

The maximum number of PoE devices the switch can support at one time is determined by its power budget and the power requirements of the devices. The switch can supply power to all of the devices as long as the their total power requirements is less than its  power budget. If the switch determines that the power requirements of the devices exceed its power budget, it denies power to one or more ports using a mechanism referred to as port prioritization.
To determine whether the power requirements of the PoE devices you plan to connect to the switch exceed its power budget, refer to their documentation for their power requirements and add the requirements together. The switch should be able to power all of  the devices simultaneously as long as the total is below its power budget. If the total exceeds the available power budget, you should consider reducing the number of PoE devices so that all of the devices receive power.
Otherwise, the switch powers a subset of the devices, based on port prioritization.
The switch can handle different power requirements on different ports. This enables you to connect different classes of PoE equipment to the ports on the switch.

Port Prioritization
If the power requirements of the powered devices exceed the switch’s power budget, the switch denies power to some ports based on a system  called port prioritization. You may use this mechanism to ensure that powered devices critical to the operations of your  network are given preferential treatment by the switch in the distribution of power should the demands of the devices exceed the available capacity.

There are three priority levels:

• Critical
• High
• Low

Ports set to the Critical level, the highest priority level, are guaranteed power before any of the ports assigned to the other two priority levels.
Ports assigned to the other priority levels receive power only if all the Critical ports are receiving power. Ports that are connected to your most critical powered devices should be assigned to this level. If there is not enough power to support all the ports set to the  Critical priority level, power is provided to the ports based on port number, in ascending order.
The High level is the second highest level. Ports set to this level receive power only if all the ports set to the Critical level are already receiving power. If there is not enough power to support all of the ports set to the High priority level, power is provided to the  ports based on port number, in ascending order.
The lowest priority level is Low. This is the default setting. Ports set to this level only receive power if all of the ports assigned to the other two levels are already receiving power. As with the other levels, if there is not enough power to support all of the ports set to  the Low priority level, power is provided to the ports based on port number, in ascending order.
Power allocation is dynamic. Ports supplying power to powered devices may cease power transmission if the switch’s power budget is at maximum usage and new powered devices, connected to ports with higher priorities, become active.

Wiring Implementation
The IEEE 802.3af standard defines two methods for the delivery of DC power over copper cable from a switch to the powered devices. These methods, known as modes A and B, identify the wires within the cable that carry the DC power from the switch to a  powered device.
Copper cabling typically consists of eight wires. With 10Base-T and 100Base-TX devices, the wires connected to pins 1, 2, 3, and 6 on the RJ- 45 connectors carry the network traffic while the wires connected to pins 4, 5, 7, and 8 are unused. With 1000Base-T  devices, all eight wires are used to carry network data.
It takes four wires to deliver DC power to a PD. With Mode A, the power is delivered on pins 1, 2, 3, and 6. These are the same pins in 10Base-T and 100Base-TX devices that carry the network data. With mode B, the power is provided over the spare wires.
The ports on the AT-x930-28GPX and AT-x930-52GPX Switches deliver the power using pins 1, 2, 3, and 6, which corresponds to mode A in the IEEE 802.3af standard. Powered devices that comply with the IEEE 802.3af standard are required to support both  power delivery methods.
Legacy devices that do not comply with the standard will work with the switch if they are powered on pins 1, 2, 3, and 6.

The twenty four ports on the AT-x930-28GSTX Switch support the following types of SFP transceivers:

• 100Base-FX, 1000Base-T, and 1000Base-SX/LX SFP transceivers
• Single-port BiDi 100Base-FX and 1000Base-LX SFP transceivers
• 1000Base-ZX SFP transceivers

The SFP ports are paired with the twenty four 10/100/1000Base-T copper ports. SFP port 1 is paired with copper port 1R, port 2 with copper port 2R, and so on. Only one port in a pair can be active at a time. For example, if you install a transceiver in SFP port 3  and connect it to an active network device, the switch deactivates copper port 3R.
Please review the following guidelines for using the SFP ports on the ATx930-28GSTX Switch:

• Each SFP port is paired with a copper port.
• You may not change the port pairings.
• Only one port in a pair can be active at a time.
• The copper port is the default active port of a pair.
• An SFP port automatically becomes active when you install and connect an SFP transceiver to an active network device.
• The switch automatically reactivates the copper port of a pair when the transceiver in the corresponding SFP port loses its link to a remote network device. For example, the switch reactivates copper port 4R if you disconnect the fiber optic cable from a  transceiver in SFP port 4.
• The letter “R” in the numbering of the copper ports on the front of the switch refers to the “redundant” function of the ports. The copper ports are only available when their corresponding SFP ports are empty or the SFP transceivers have not established  links with network devices.

SFP+ Ports
The switches have four SFP+ ports that support the following types of SFP 1000Mbps and SFP+ 10Gbps transceivers:

• 1000Base-SX/LX SFP transceivers
• Single-port BiDi 1000Base-LX SFP transceivers
• 1000Base-ZX SFP transceivers
• 10Gbps, 10GBase-SR/LR fiber optic transceivers
• 10Gbps AT-SP10TW direct connect twinax cables with SFP+ transceiver-style connectors
• 10Gbps AT-SP10TW1 and AT-SP10TW3 1- and 3-meter SFP+ direct attach cables

You may use the ports and transceivers to connect switches to other network devices over large distances, build high-speed backbone networks between network devices, or connect high-speed devices, such as servers, to your network.
The switches support a variety of short and long distance SFP and SFP+ modules. For a list of supported SFP modules, refer to the product’s data sheet on the Allied Telesis website.

Note
The SFP+ ports do not support 100Mbps 100Base-FX transceivers.
Note
The ports support full-duplex mode only.They do not support halfduplex mode.
Note
SFP and SFP+ transceivers must be purchased separately.
Note
SFP+ ports 27/S1 and 28/S2 on the AT-x930-28GTX, AT-x93028GSTX, and AT-x930-28GPX Switches and ports 51/S1 and 52/S2 on the AT-x930-52GTX and AT-x930-52GPX Switches are initially configured as stacking ports for the VCStack feature. You can  use them as regular Ethernet ports by disabling VCStack or by using other switch ports for the stack trunk. Refer to x930 Installation Guide for Virtual Chassis Stacking for more information.

S1 and S2 SFP+ Ports
SFP+ ports 27/S1 and 28/S2 on the front panels of the 28-port switches and 51/S1 and 52/S2 on the 52-port switches can be used either as regular Ethernet networking ports or as the trunk in a stack of up to eight switches with the VCStack feature. The switches  of a VCStack act as a single virtual unit, synchronizing their actions so that switching operations, like spanning tree protocols, virtual LANs, and static port trunks, span across all of the units and ports. For more information, refer to x930 Installation Guide for  Virtual Chassis Stacking.

Note
For a list of supported transceivers, refer to the product’s data sheet on the Allied Telesis web site.
Note
The S1 and S2 ports are the default stack trunk ports if the switch does not contain the AT-StackQS Card. To use the ports are regular Ethernet networking ports, you must disable VCStack or use other switch ports for the stack trunk. The ports on the AT- StackQS Card are the default stack trunk ports if the card is installed.

Ethernet Management Port (NET MGMT)
The NET MGMT port in the management panel of the switch is a separate routed eth0 interface. The interface is not part of the switching matrix of the Ethernet line cards, but the CPU on the controller card can route traffic in or out of the port.
Here are the guidelines to using the port:

• The port should only be used for initial configuration and maintenance access to the chassis.
• The NET MGMT port has a standard RJ-45 8-pin connector and operates at 10, 100, or 1000 Mbps in either half- or full-duplex mode.
• The cable requirements for the port are the same as the ports on the AT-x930-28GTX Switch, listed in “Cable Requirements” on page 32. For the port pinouts, refer to “RJ-45 Copper Port Pinouts” on page 210.
• The default setting for the port is Auto-Negotiation, which sets the speed and duplex mode automatically. You may disable AutoNegotiation and configure the port manually.
• The wiring configuration of the NET MGMT port is set automaticallywith automatic MDIX detection. You may disable automatic MDIX detection and set the wiring configuration manually.
• The port is referred to as eth0 in the management software.

For instructions on how to configure the NET MGMT port, refer to the Software Reference for x930 Series Switches.

NET MGMT LEDs

The Network Management (NET MGMT) port on the switch has two Status LEDs, described in Table 6.
Table 6. NET MGMT Port LED

eco-friendly Button
The eco-friendly button on the front panel of the switch is used to toggle the port LEDs on or off. You might turn off the LEDs to conserve electricity when you are not monitoring the device. You can also toggle the LEDs with the ECOFRIENDLY LED and NO  ECOFRIENDLY LED commands in the Global Configuration mode of the command line interface. The switch is said to be operating in a low power mode when the LEDs are turned off.
Operating the switch in the low power mode with the LEDs turned off does not interfere with the network operations of the device.
The management software on the switch has a command that blinks the LEDs so that you can quickly and easily identify a specific unit among the devices in an equipment rack. It is the FINDME command. The command works on the switch even if you turned  off the LEDs with the eco-friendly button or NO ECOFRIENDLY LED command.
The Switch ID LED is always on, but it displays different information depending on whether the LEDs are on or off. When the LEDs are on, the ID LED displays the ID number of the switch. When the switch is operating in the low power mode with the LEDs off,  the ID LED indicates whether the switch is a standalone unit or the master or member switch of a VCStack, as detailed in Figure 14 on page 50.
Note
Before checking or troubleshooting the network connections to the ports on the switch, you should always check to be sure that the LEDs are on by either pressing the eco-friendly button or issuing the ECOFRIENDLY LED and NO ECOFRIENDLY LED  commands in the Global Configuration mode of the command line interface.

USB Port
The management panel has a USB port. You may use the port to store configuration files on flash drives or to restore configuration files to switches whose settings have been lost or corrupted, or to quickly configure replacement units. You may also use the port  and flash drives to update the management firmware on the switch.
The port is USB2.0 compatible.

Console Port
You use the Console port to manage the switch and configure its features and parameter settings. This type of management uses serial RS-232 and is commonly referred to as local management because it is not conducted over your network. To perform local  management, you must be at the location of the switch and use the management cable included with the device.
To establish a local management session with the switch, connect a terminal or a personal computer with a terminal emulation program to the Console port, which has an RJ-45 style (8P8C) connector, using the provided management cable. The cable has RJ-45  style (8P8C) and DB-9 (D-sub 9-pin) connectors.
To connect a laptop/desktop computer and a network device, such as a switch, you can use the AT-VT-Kit3 management cable. The cable is a USB-to-Serial converter with a USB-A male connector on one end and an RJ-45 female receptor on the other end.

Note
To use the AT-VT-Kit3 management cable, you must install the driver software onto your Windows system. For installation instructions, refer to Allied Telesis Quick Installation Guide AT-VTKit3 Management Cable.

The Console port is set to the following specifications:

• Default baud rate: 9600 bps (Range is 9600 to 115200 bps)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None

Note
These settings are for a DEC VT100 or ANSI terminal, or an equivalent terminal emulation program.

You must disable it by performing the steps in the rest of this procedure before using the SFP+ S1 and S2 stacking slots with  regular SFP or SFP+ transceivers. The reason the status says “standalone” is because the switch is functioning as a stack of one switch.

5. Move to the Global Configuration mode by entering the ENABLE and CONFIGURE TERMINAL commands, as shown in Figure 67.
   

6. To. disable the VCStack feature on the switch, enter the NO STACK ENABLE command, which has this format: no stack id enable
   The ID parameter is the ID number of the switch, displayed on the ID LED. Replace the parameter with whatever number is on the ID LED.
   For example, if the ID number of the switch is 1, the default value, enter the command as follows: awplus(config)# no stack 1 enable
   This confirmation prompt in Figure 68 is displayed.
   

7. Type Y to disable VCStack on the switch or N to cancel the procedure.
   The switch displays the message in Figure 69.
   

8. Press the Return key to re-display the Global Configuration mode prompt.

9. Enter the EXIT command to return to the Privileged Exec mode, as shown in Figure 70.
   

10. Enter the WRITE command to save your change in the configuration file. The switch displays the confirmation prompt in Figure 71.
    If this is the initial management session, the switch automatically creates the Default.cfg configuration file and stores your change in the file.

11. Enter the REBOOT command to reboot the switch.

12. At the confirmation prompt, type “Y” for yes.

13. Wait two minutes for the switch to initialize its management software and afterwards examine the Switch ID LED again. The switch is ready for normal network operations as a standalone unit when its ID number is “0.” If the number is not “0,” repeat this  procedure. Be sure to save the configuration change with the WRITE command in step 10.

14. Do one of the following:
     If the switch contains the optional AT-StackQS or AT-x9EM/XT4 Card, go to “Verifying Support for Hardware Options” on page 132.
     If the switch does not contain the optional AT-StackQS or ATx9EM/XT4 Card, go to Chapter 11, “Cabling the Networking Ports” on page 133.

Verifying Support for Hardware Options
This section contains the procedure for viewing the version number of the management software on the switch. Allied Telesis recommends performing this procedure if you installed the optional AT-StackQS or ATx9EM/XT4 Module. The module requires version 5.4.5-2 or later of the management software.
To view the version number of the management software, perform the following procedure. If the switch is powered off, start with step 1. If the switch is already powered on, start with step 3:

1. Power on one of the switches by doing one of the following:
    If the switch has an AC power supply, connect the AC power cord to the power supply on the back panel and to an AC power source. if the switch has two power supplies, you need to power on only one of them for this procedure.
    If the switch has the DC AT-PWR250-80 Power Supply, power on the DC circuit and the On/Off switch on the power supply. (If you have not yet wired the DC connector on the power supply, refer to Chapter 8, “Wiring the DC Connector on the AT- PWR250-80 Power Supply” on page 111.)

2. Wait one minute for the switch to initialize the management software.

3. Start a local management session on the switch. For instructions, refer to “Starting a Local Management Session” on page 127.

4. In the User Exec mode, enter either the SHOW SYSTEM or SHOW VERSION command.

5. Examine the Software Version field in the information the command displays on your screen and do one of the following:
    If the field says “545-2” or later, the management software on the switch supports the AT-x9EM/XT4 Module. Go to Chapter 11, “Cabling the Networking Ports” on page 133.
    If the field says “545” or “545-1”, the management software does not support the optional module. You must update the operating software on the switch to the latest release before you can use the module. For upgrade instructions, refer to the Software  Reference for x930 Series Switches, AlliedWare Operating System from www.alliedtelesis.com.

Chapter 11 Cabling the Networking Ports

This chapter contains the following procedures:

• “Cabling Copper Ports” on page 134
• “Installing SFP or SFP+ Transceivers” on page 136
• “Specifying Ports in the Command Line Interface for Standalone Switches” on page 141
• “Installing AT-SP10TW Direct Connect Cables” on page 143
• “Cabling the AT-StackQS Card with AT-QSFPICU Cables” on page 145
• “Cabling the AT-StackQS Card with Fiber Optic Transceivers” on page 147

Cabling Copper Ports
Here are the guidelines to cabling the 10/100/1000Base-T copper ports:

• The cable specifications for the ports are listed in “Cable Requirements” on page 32.

• The connectors on the cables should fit snugly into the ports, and the tabs should lock the connectors into place.

• The default setting for the wiring configurations is auto-MDI/MDI-X.
  The default setting is appropriate for switch ports that are connected to 10 /100Base-TX network devices that also support auto-MDI/MDI-X.

• The default auto-MDI/MDI-X setting is not appropriate for switch ports that are connected to 10/100Base-TX network devices that do not support auto-MDI/MDI-X and have a fixed wiring configuration. For switch ports connected to those types of  network devices, you should disable auto-MDI/MDI-X and set the wiring configurations manually.

• The appropriate MDI/MDI-X setting for a switch port connected to a 10/100Base-TX network device with a fixed wiring configuration depends on the setting of the network device and whether the switch and network device are connected with straight- through or crossover cable. If you are using straight-through copper cable, the wiring configurations of a port on the switch and a port on a network device must be opposite each other, such that one port uses MDI and the other MDI-X. For example, if a  network device has a fixed wiring configuration of MDI, you must disable auto-MDI/ MDI-X on the corresponding switch port and manually set it to MDI-X. If you are using crossover copper cable, the wiring configurations of a port on the switch and a  port on a network device must be the same.

• The default speed setting for the ports is Auto-Negotiation. This setting is appropriate for ports connected to network devices that also support Auto-Negotiation.

• The default speed setting of Auto-Negotiation is not appropriate for ports connected to 10/100Base-TX network devices that do not support Auto-Negotiation and have fixed speeds. For those switch ports, you should disable Auto-Negotiation and set the  port’s speed manually to match the speeds of the network devices.

• The 10/100/1000Base-T ports must be set to Auto-Negotiation, the default setting, to operate at 1000Mbps.

• The default duplex mode setting for the ports is Auto-Negotiation.
  This setting is appropriate for ports connected to network devices that also support Auto-Negotiation for duplex modes.

• The default duplex mode setting of Auto-Negotiation is not appropriate for ports connected to network devices that do not support Auto-Negotiation and have a fixed duplex mode. You should disable Auto-Negotiation on those ports and set their duplex modes manually to avoid the possibility of duplex mode mismatches. A switch port using Auto-Negotiation defaults to halfduplex if it detects that the end node is not using Auto-Negotiation, which can result in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.

• Do not attach cables to ports of static or LACP port trunks until after you have configured the trunks on the switch. Otherwise, the ports will form network loops that can adversely affect network performance.

Installing SFP or SFP+ Transceivers
Please review the following guidelines before installing SFP or SFP+ transceivers in the switch:
Note
Refer to the product’s data sheet on the Allied Telesis web site for a list of supported transceivers.

Here are the guidelines:

• Ports 25 to 28 on 28-port x930 switches and ports 49 to 52 on 52port switches support 1000Mbps SFP and 10Gbps SFP+ transceivers. They do not support 100Mbps SFP transceivers.
• Ports 1 to 24 on the AT-x930-28GSTX Switch support 100/ 1000Mbps SFP transceivers. They do not support 10Gbps SFP+ transceivers.
• If you are using SFP+ ports S1 and S2 as the VCStack trunk, review the guidelines in “Trunks of Ports S1 and S2” on page 60 before performing this procedure.
• SFP and SFP+ transceivers are hot-swappable. You may install them while the switch is powered on.
• The operational specifications and fiber optic cable requirements of the transceivers are provided in the documents included with the devices.
• You should install a transceiver before connecting the fiber optic cable.
• Fiber optic transceivers are dust sensitive. Always keep the plug in the optical bores when a fiber optic cable is not installed, or when you store the transceiver. When you do remove the plug, keep it for future use.
• Unnecessary removal and insertion of a transceiver can lead to premature failure.

Warning
Transceivers can be damaged by static electricity. Be sure to observe all standard electrostatic discharge (ESD) precautions, such as wearing an antistatic wrist strap, to avoid damaging the devices. E92

Note
SFP+ slots 27/S1 and 28/S2 on the 28-port switches and slots 51/S1 and 52/S2 on the 52-port switches are initially configured as stacking slots for the VCStack feature. If you intend to use the switch as a standalone unit, you must disable the VCStack feature  before using the slots with standard SFP or SFP+ transceivers. For instructions, refer to Chapter 9, “Powering On the Switch” on page 115.

The illustrations in the procedure show the installation of a transceiver in port 25 of a 28-port switch. The procedure is the same for all SFP and SFP+ ports. The transceiver in the illustrations has a duplex LC connector.
Your transceivers may have different connectors.
To install transceivers, perform the following procedure:

1. If the transceiver port has a dust plug, remove it. Refer to Figure 72.
   

2. Remove the transceiver from its shipping container and store the packaging material in a safe location.

3. If you are installing the transceiver in a top slot, position the transceiver with the Allied Telesis label facing up. If you are installing the transceiver in a bottom slot, position the transceiver with the label facing down.

4. Slide the transceiver into the port until it clicks into place, as shown in Figure 73 on page 139.
   Note
   If you are ready to attach the fiber optic cable to the transceiver, continue with the next step. Otherwise, repeat steps 1 to 4 to install the remaining transceivers in the switch.

5. Remove the dust cover from the transceiver, as shown in Figure 74.
   

6. Verify the position of the handle on the transceiver. If the transceiver is in a top slot, the handle should be in the upright position, as shown in Figure 75 on page 140. If the transceiver is in a bottom slot, the handle should be in the down position.
   

7. Connect the fiber optic cable to the transceiver, as shown in Figure 76.
   The connector on the cable should fit snugly into the port, and the tab should lock the connector into place.
   

8. Repeat this procedure to install additional transceivers.

Specifying Ports in the Command Line Interface for Standalone Switches
The individual ports on the switches of the stack are specified in the command line interface with the PORT parameter. The format of the parameter is shown in Figure 77.

The three parts of the PORT parameter are described in Table 17.
Table 17. PORT Parameter Format

Chapter 12 Troubleshooting

This chapter contains suggestions on how to troubleshoot the switch if a problem occurs.
Note
For further assistance, please contact Allied Telesis Technical Support at www.alliedtelesis.com/support.

Problem 1 : All of the port LEDs and the Switch ID LED are off, and the fans are not operating.
Solutions: The unit is not receiving power. Try the following:

• Verify that the power cord is securely connected to the power source and to the AC connector on the back panel of the switch.
• Verify that the power outlet has power by connecting another device to it.
• Try connecting the unit to another power source.
• Try a different power cord.
• Verify that the voltage from the power source is within the required levels for your region.

If the switch has the DC AT-PWR250-80 Power Supply, try the following:

• Verify that the DC circuit is powered on.
• Verify that the On/Off switch on the power supply is in the On position.
• Verify that the positive, negative, and ground wires are properly connected to the AT-PWR250-80 Power Supply and DC circuit.
  Refer to “Wiring the DC Connector on the AT-PWR250-80 Power Supply” on page

• Try connecting the switch to another DC circuit.
• Try replacing the positive, negative, and ground wires.

Problem 2: All of the port LEDs are off even though the ports are connected to active network devices.
Solution: The switch may be operating in the low power mode. To toggle on the LEDs, press the eco-friendly button on the front panel of the switch.
You may also toggle the LEDs off and on with the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in the command line interface.
Problem 3 : A copper port on the switch is connected to a network device but the port’s LINK/ACT LED is off.
Solutions: The port is unable to establish a link to a network device. Try the following:

• Verify that the port is connected to the correct copper cable. This is to eliminate the possibility that the port is connected to the wrong network device.

• Verify that the network device connected to the port is powered on and is operating properly.

• Try connecting another network device to the port with a different cable. If the port is able to establish a link, then the problem is with the cable or the other network device.

• Verify that the copper cable does not exceed 100 meters (328 feet).

• Verify that you are using the appropriate category of copper cable.
  The cable types are listed in “Cable Requirements” on page 32 for the 10/100/1000Base-T ports.

• Verify that the companion SFP port of the copper port is empty.
  This applies only to the AT-x930-28GSTX Switch. For example, if copper port 2R is connected to an active network device but cannot establish a connection to it, verify that SFP port 2 is empty.
  For more information, refer to “SFP Ports” on page 38.
  Note
  A 1000Base connection may require five to ten seconds to establish a link.

Problem 4: The LINK/ACT LED for an SFP or SFP+ transceiver is off.
Solutions: The fiber optic port on the transceiver is unable to establish a link to a network device. Try the following:

• Verify that the remote network device connected to the fiber optic port is operating properly.

• Check that the transceiver is fully inserted in the port.

• Verify that the fiber optic cable is securely connected to the port on the SFP or SFP+ module and to the port on the remote device.

• Verify that the operating specifications of the fiber optic ports on the transceiver and remote network device are compatible.

• Verify that the correct type of fiber optic cabling is being used.

• Verify that the port is connected to the correct fiber optic cable.
  This is to eliminate the possibility that the port is connected to the wrong remote network device.

• Try connecting another network device to the fiber optic port using a different cable. If the port is able to establish a link, then the problem is with the cable or with the other network device.

• Use the switch’s management software to verify that the port is enabled.

• If the remote network device is a managed device, use its management firmware to determine whether its port is enabled.

• Test the attenuation of both directions on the fiber optic cable with a fiber optic tester to determine whether the optical signal is too weak (sensitivity) or too strong (maximum input power)

Problem 5: Network performance between a copper port on the switch and a network device is slow.
Solution: There might be a duplex mode mismatch between the port and the network device. This can occur when a copper port using AutoNegotiation is connected to a remote device that has a fixed speed of 10 or 100 Mbps and a fixed duplex mode of full duplex. If this is the cause of the problem, adjust the duplex mode of the port on the network device or switch so that both ports are using the same duplex mode. You can use either the LEDs or management software on the switch to determine the duplex mode  settings of the ports. The LEDs are described in Table 7 on page 44.

Problem 6: The switch functions intermittently.
Solutions: Check the system hardware status through the management software:

• Use the SHOW SYSTEM ENVIRONMENT command in the Privileged Exec mode to verify that the input voltage from the power source to the switch is stable and within the approved operating range. The unit will shut down if the input voltage fluctuates  above or below the approved operating range.
• Use the SHOW SYSTEM ENVIRONMENT command in the Privileged Exec mode to verify that the fan is operating correctly.
• Verify that the location of the switch allows for adequate airflow.
  The unit will shut down if it is in danger of overheating.

Problem 7: The Switch ID LED on the front of the switch is flashing the letter “F.”
Solutions: One or more of the following problems has occurred:

• A cooling fan has failed.
• The internal temperature of the switch has exceeded the normal operating range and the switch may shut down.

Contact your Allied Telesis sales representative for assistance.
Problem 8: A port on the AT-x930-28GPX or AT-x930-52GPX Switch is not providing power to a PoE device.
Solutions: Try the following:

• Review the PD’s documentation to confirm that the device supports Mode A of the IEEE 802.3at standard. Mode A is one of two modes that define the connector pins that deliver the power from the port in the switch to the powered device. In Mode A, the power is carried on pins 1, 2, 3, and 6 on the RJ-45 port, the same  pins that carry the network traffic. The second mode, Mode B, defines pins 4, 5, 7, and 8 as the power carriers. The AT-x93028GPX and AT-x930-52GPX Switches do not support Mode B. Most powered devices are designed to accept power by either mode, but some legacy devices may only support one mode. This can be verified by reviewing the device’s documentation or data sheet. Legacy devices that only support Mode B will not work with the switches.
• Check that the device’s power requirements do not exceed 30 W. This can be verified by reviewing the device’s documentation or data sheet.
• Verify that you are using the appropriate category of copper cable by referring to “Cable Requirements” on page 32.
• Use the management software on the switch to determine whether PoE is enabled on the port. The default setting for PoE is enabled.
• Use the management software on the switch to determine whether the PoE power setting for the port has been reduced to a value below the power requirements of the device.
• Try connecting the device to a different port on the switch.

Problem 9 : One or more ports on the optional AT-StackQS or AT-x9EM/ XT Card cannot establish connections to network devices or do not forward traffic.
Solutions: Try the following:

• Verify that the switch has version 5.4.5-2 or later of the x930 operating system. Earlier versions of the management software do not support the card. For instructions, refer to “Verifying Support for Hardware Options” on page 132.
• Verify that you are using UTP or STP Cat. 5e for 1Gbps links and UTP or STP Cat. 6e cable for 10Gbps links.
• Verify that the port is connected to the correct copper cable. This is to eliminate the possibility that the port is connected to the wrong network device.
• Verify that the network device connected to the port is powered on and is operating properly.
• Try connecting another network device to the port with a different cable. If the port is able to establish a link, then the problem is with the cable or the other network device.
• Verify that the copper cable does not exceed 100 meters (328 feet).
