General Precautions for Rack-Mountable Products

• Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation accompanying the system and the rack for specific caution statements and procedures.

• Systems are considered to be components in a rack. Thus, “component” refers to any system as well as to various peripherals or supporting hardware.
  CAUTION:
  

  • Installing systems in a rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack.
  • After installing system/components in a rack, never pull more than one component out of the rack on its slide assemblies at one time. The weight of more than one extended component could cause the rack to tip over and may result in serious injury.

• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joining multiple racks before working on the rack.

• Always load the rack from the bottom up, and load the heaviest item in the rack first.

• Make sure that the rack is level and stable before extending a component from the rack.

• Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers.

• After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack.

• Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80 per cent of the branch circuit rating.

• Ensure that proper airflow is provided to components in the rack.

• Do not step on or stand on any component when servicing other components in a rack.

• CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

• CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to connect power to the system until grounding cables are connected. Completed power and safety ground wiring must be inspected by a qualified electrical inspector. An energy hazard will exist if the safety ground cable is omitted or disconnected.

Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of the electronic components, such as the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

1. When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads, and an antistatic grounding strap.

Switch Description

The 16-port DGS-1016D and 24-port DGS-1024D Switches provide dedicated 10, 100 or 1000 Mbps Ethernet bandwidth on each port. The ports will automatically detect the speed, duplex and MDI/MDIX status of the device it is connecting to, and adjust these settings accordingly. The Switch ports can be used to network computers, printers, servers, routers, other switches or any device equipped with an Ethernet port. For best performance, use Category 5 or better Ethernet cabling.

This stand-alone Switch is very easy to set up, there is no network management required. Just power on the Switch and connect the cables. Keep in mind however that the standard rules of Ethernet regarding cable length apply to this and all Ethernet devices. The length of an Ethernet cable from one device to another cannot exceed 100 meters (or 300 feet).

Switch Features

The DGS-1016D 16-port and DGS-1024D 24-port Switches do not require any management. Both Switches are designed for easy installation, flexibility and high performance. Connect devices to the Switch as the scale and volume of network traffic increases.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software and trained personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their bus speeds get faster and more users to use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnets.

Gigabit Ethernet supports video conferencing, complex imaging and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NICs can perform 10 times the number of operations in the same amount of time.

802.1P and QoS
The DGS-1024D and DGS-1016D Switches support 802.1p priority queuing Quality of Service. The implementation of QoS (Quality of Service) and the benefits of using 802.1p priority queuing are described here.

Advantages of QoS
QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over- Internet Protocol), web browsing applications, file server applications or video conferencing. Not only can a larger bandwidth be created, but other less critical traffic can be limited, so bandwidth can be saved. The Switch has separate hardware queues on every physical port to which packets from various applications are mapped to and assigned a priority. The illustration below shows how 802.1P priority queuing is implemented on the Switch. The eight IEEE 802.1P priority levels defined by the standard are mapped to the four class queues used in the Switch.

Mapping QoS on the Switch
The picture above shows the default priority setting for the Switch. Class 3 has the highest priority of the four priority queues on the Switch. In order to implement QoS, the user is required to instruct the Switch to examine the header of a packet to see if it has the proper identifying tag tagged. Then the user may forward these tagged packets to designated queues on the Switch where they will be emptied, based on priority. “The DUT support strict mode for 802.1p QoS. The untagged pkt will follow the priority 0 to work (i.e. class 1).”

Understanding QoS.
The Switch has four priority queues. These priority queues are labelled as 3, the high queue to 0, the lowest queue. The eight priority tags, specified in IEEE 802.1p are mapped to the Switch’s priority tags as follows:

• Priority 0 is assigned to the Switch’s Q1 queue.
• Priority 1 is assigned to the Switch’s Q0 queue.
• Priority 2 is assigned to the Switch’s Q0 queue.
• Priority 3 is assigned to the Switch’s Q1 queue.
• Priority 4 is assigned to the Switch’s Q2 queue.
• Priority 5 is assigned to the Switch’s Q2 queue.
• Priority 6 is assigned to the Switch’s Q3 queue.
• Priority 7 is assigned to the Switch’s Q3 queue.

The Switch uses strict priority for Scheduling. Strict priority-based scheduling, any packets residing in the higher priority queues are transmitted first.

Front-Panel Components

Note: The Switch illustrations used for this manual depict only the model DGS-1016D Switch.

On the front panel of the Switch, you will see the following.

• LED status indicators
• 16 Auto-Negotiating 10/100/1000Mbps ports on the DGS -1016D
• 24 Auto-Negotiating 10/100/1000Mbps ports on the DGS -1024D

LED Indicators

The LED indicators of the Switch include a Power status indicator, one Link/Act indicator for each port as well as one speed 100/1000Mbps indicator for each port. When the Switch is powered on or restarted, it initiates a diagnostic function as part of the bootup process. The speed indicators are also used to display cable diagnostic information when the Switch boots up.

Cable Diagnostic.
Upon booting up the Switch, a Cable Diagnostic is used to detect three problems that may prevent successful connection. This feature operates only on ports that are connected to 1000Mbps devices. If there are problems on a port connected to a Gigabit Ethernet device (1000Mbps), try restarting the Switch and watch the speed (100/1000Mbps) LED indicators to determine is the problem is a fault in the cable or connecting hardware. For ports operating at 10 or 100Mbps, the LED indicators can be used for less specific troubleshooting.

The faults detected by the cable diagnostic for 1000Mbps operation are as follows:

• Open circuit – a lack of continuity between the pins at each end of the Ethernet cable or a disconnected cable.
• Short circuit – two or more conductors short-circuited.
• Connectivity is checked for each of the eight wires of a cable to ensure its capability for running 1000Mbps.

During the diagnostic, each port is scanned to determine if the Ethernet cable and connectors is in good working order. During the diagnostic process the speed LED for each port blinks green in sequential order. This port scan takes about 3 seconds. If a cable fault is detected, the corresponding port’s speed LED will light amber for 5 seconds. The Switch is then reset for normal operation. It takes about 2 seconds for the Switch to reset. The entire Cable Diagnostic process takes about 10 seconds from the time the Switch is powered on.

The table below summarizes Cable Diagnostic information.

NOTE:
The cable diagnostic function does not detect the length of Ethernet cabling. Remember that the length of cabling between two Ethernet devices may not exceed 100 meters (or 300 feet).

connected and a valid link is established. This will blink green when there is activity on the port.
100Mbps/1000Mbps| The speed indicator will light green if the corresponding port is connected and operating at 1000Mbps. An amber light indicates the port is operating at 100Mbps. If the port is connected (as indicated by the Link/Act indicator) and the speed indicator does not light, the port is operating at 10Mbps.

• CSMA/CD – Channel access method used by Ethernet and IEEE 802.3 standards, in which devices transmit only after finding the data channel clear for some time. When two devices transmit simultaneously, a collision occurs and the colliding devices delay their retransmissions for a random amount of time.
• data centre switching – The point of aggregation within a corporate network where a switch provides high-performance access to server farms, a high-speed backbone connection, and a control point for network management and security.
• Ethernet – A LAN specification developed jointly by Xerox, Intel, and Digital Equipment Corporation. Ethernet networks operate at 10Mbps using CSMA/CD to run over cabling.
• Fast Ethernet – 100Mbps technology based on the Ethernet/CD network access method.
• Flow Control – (IEEE 802.3x) A means of holding packets back at the transmit port of the connected end station. Prevents packet loss at a congested switch port.
• forwarding – The process of sending a packet toward its destination by an internetworking device.
• Full-duplex – A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link.
• Half-duplex – A system that allows packets to be transmitted and received, but not at the same time. Contrast with full-duplex.
• IP address – Internet Protocol address. A unique identifier for a device attached to a network using TCP/IP. The address is written as four octets separated with full stops (periods) and is made up of a network section, an optional subnet section and a host section.
• IPX – Internetwork Packet Exchange. A protocol allowing communication in a NetWare network.
• LAN – Local Area Network. A network of connected computing resources (such as PCs, printers, servers) covering a relatively small geographic area (usually not larger than a floor or building). Characterized by high data rates and low error rates.
• latency – The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port.
• line speed – See baud rate.
• main port – The port in a resilient link that carries data traffic in normal operating conditions.
• MDI – Medium Dependent Interface. An Ethernet port connection is where the transmitter of one device is connected to the receiver of another device.
• MDI-X – Medium Dependent Interface Cross-over. An Ethernet port connection where the internal transmit and receive lines are crossed.
• MIB – Management Information Base. Stores a device’s management characteristics and parameters. MIBs are used by the Simple Network Management Protocol (SNMP) to contain attributes of their managed systems. The Switch contains its own internal MIB.
• multicast – Single packets copied to a specific subset of network addresses. These addresses are specified in the destination-address field of the packet.
• protocol – A set of rules for communication between devices on a network. The rules dictate format, timing, sequencing, and error control.
• resilient link – A pair of ports that can be configured so that one will take over data transmission should the other fail. See also the main port and standby port.
• RJ-45 – Standard 8-wire connectors for IEEE 802.3 10BASE-T networks.
• RMON – Remote Monitoring. A subset of SNMP MIB-II, which allows monitoring and management capabilities by addressing up to ten different groups of information.
• RPS – Redundant Power System. A device that provides a backup source of power when connected to the Switch.
• server farm – A cluster of servers in a centralized location serving a large user population.
• SLIP – Serial Line Internet Protocol. A protocol that allows IP to run over a serial line connection.
• SNMP – Simple Network Management Protocol. A protocol originally designed to be used in managing TCP /IP internets. SNMP is presently implemented on a wide range of computers and networking equipment and may be used to manage many aspects of network and end-station operation.
• Spanning Tree Protocol – (STP) A bridge-based system for providing fault tolerance on networks. STP works by allowing you to implement parallel paths for network traffic, and to ensure that redundant paths are disabled when the main paths are operational and enabled if the main paths fail.
• stack – A group of network devices that are integrated to form a single logical device.
• standby port – The port in a resilient link that will take over data transmission if the main port in the link fails.
• switch – A device that filters, forwards, and floods packets based on the packet’s destination address. The Switch learns the addresses associated with each switch port and builds tables based on this information to be used for the switching decision.
• TCP/IP – A layered set of communications protocols providing Telnet terminal emulation, FTP file transfer, and other services for communication among a wide range of computer equipment.
• Telnet – A TCP/IP application protocol that provides virtual terminal service, letting a user log in to another computer system and access a host as if the user were connected directly to the host.
• TFTP – Trivial File Transfer Protocol. Allows you to transfer files (such as software upgrades) from a remote device using your switch’s local management capabilities.
• UDP – User Datagram Protocol. An Internet standard protocol that allows an application program on one device to send a datagram to an application program on another device.
• VLAN – Virtual LAN. A group of location- and topology-independent devices that communicate as if they are on a common physical LAN.
• VLT – Virtual LAN Trunk. A Switch-to-Switch link which carries traffic for all the VLANs on each Switch.
• VT100 – A type of terminal that uses ASCII characters. VT100 screens have a text-based appearance.
