Chapter 2: Overview

2. Overview: About the IE GIGA MC TX/SFP
The IE GIGA MC TX/SFP is an SNMP manageable standalone device providing two fixed 10/100/1000Base-T copper ports and 2 SFP ports. The SFP ports support fiber or copper SFPs. As a plug and play device, the IE GIGA MC TX/SFP provides several distinct modes of operation to support a wide range of applications. The IE GIGA MC TX/SFP provides OAM functionality with 802.3ah (LINK-OAM ah) and 802.1ag (SERVICE-OAM ag) supported on each port. It supports jumbo frame sizes of up to 10,240 bytes as well as AutoCross on the copper ports. Power options for the IE GIGA MC TX/SFP include both a standard low voltage wall transformer and a Power Block for Office Battery or a DC Power Supply connection. As an Industrial Ethernet device, it supports an extended temperature range of -40°C to +85°C. A console port and a DIP Switch bay provide configuration options.
The IE GIGA MC TX/SFP can be directly managed, because it contains onboard logic. Management capability is available if the device has firmware version 123-00A1 or higher, which can be downloaded from the Black Box site. iView2 is a free software, posted on the website under Support/Downloads. Please refer to page 12 for details.
The IE GIGA MC TX/SFP requires two small form-factor (SFP) modules which provide greater flexibility in the network environment. The hot-swappable nature of the SFPs, available in dual strand for Multi Mode and Single Mode, and single strand fiber types for Single Mode, allow for easy configuration and future upgrading as network demands evolve. The SFP modules must be MSA- compliant and both DDMI and non-DDMI are supported. The fiber SFP can support 100Mbps or 1000Mbps; while the copper SFPs support 10/100/1000Mbps and 1000Mbps.
SFPs are sold separately and meet Class 1 Laser Safety Standard.

3.1 Operations, Administration and Maintenance (OAM)
OAM is a general term used in network management and is typically applied to a series of standard protocols for installing, monitoring, and troubleshooting Metropolitan Area Networks.

LGC340A-R2

877-877-2269 | blackbox.com

Page 11

Chapter 3: Configuration

When applied to Ethernet ­ OAM is typically assumed to refer to the layer 2 (MAC layer), management protocols, specifically 802.3ah and 802.1ag. Layer 2 management protocols do not need higher level transport protocols to operate, OAM data is transferred in standard multicast Ethernet frames.

802.3ah OAM: (LINK-OAM)
802.1ag: (SERVICE-OAM)

Is a point-to-point protocol designed to verify a specific link between two directly connected devices (over copper or fiber), which support 802.3ah OAM. One device must be configured to be an active OAM device, the other a passive (typically the core switch would be the active device, the end device passive). 802.3ah OAM provides link status, remote fault detection and the ability to initiate a loopback circuit.
Often referred to as Connectivity Fault Management (CFM), is an end-to-end protocol designed to verify a specific network path between two devices that may well be in different geographical locations. CFM allows the network operator to administer, monitor and debug the network using continuity check (a heart beat message), link trace (similar to traceroot, but operating at the MAC layer) and finally loopback (can be likened to a layer 2 ping).

3.2 iView² Management Software

iView² is the Black Box management software that features a Graphical User Interface (GUI) and gives network managers the ability to monitor and control the manageable Black Box products.

iView² is available in several versions, including a WebServer version 3.0, and can also function as a snap-in module for HP OpenView Network Node Manager and other third party SNMP Management software.

iView2 supports Windows® Operating systems.
Please see the SNMP Management Module manual for software configuration options.

Chapter 3: Configuration

3.3 iView2 (iConfig view)
iView2 (iConfig view) is an in-band utility created by Black Box, used for SNMP configuration for Black Box’s SNMP-manageable devices.
The iView2 (iConfig view) feature allows the following to be performed:
· Set an IP address, subnet mask and default gateway
· Define community strings and SNMP Traps
iView2 (iConfig view) also includes an authorized IP address system and restricted access to MIB groups which are supported by Black Box’s manageable devices. These extra layers of security do not affect SNMP compatibility. iView2 (iConfig view) can upload new versions of the system software and new MIB information. It also includes diagnostic capabilities for faster resolution of technical support issues.

3.4 Configuration via DIP Switch Settings

The IE GIGA MC TX/SFP can be configured in one of the following ways via DIP Switch settings:

Configuration Description Method

4-Port Switch (default)

In this mode, the unit acts as a standard 4-port MAC-layer switch. In this configuration, IEEE802.3ah Passive is enabled on both fiber ports, and can be enabled on the RJ45 ports through the CLI.

Dual Converter mode

In this configuration, the unit functions as two independent (SFP to TX) media converters and traffic never passes between the two converters.

1+1 SFP Protection Non-Revertive mode

In this mode, the “SFP A” port (fiber or copper) is connected through the switch to the drop ports as the main link. The “SFP B” port (fiber or copper) is active into the MAC switch, but no connection inside the switch is made; in this way, the “SFP B” line is held as the standby line. The “SFP B” line is held in the LINK state for testing and line verification, but does not actively carry user data.

When a fault is detected on the active line, all customer traffic is switched to the “SFP B” port. With non-Revertive mode data is not resumed by “SFP A” port.

1+1 SFP Protection Revertive mode

In this mode, the “SFP A” port (fiber or copper) is connected through the switch to the drop ports as the main link. The “SFP B” port (fiber or copper) is active into the MAC switch, but no connection inside the switch is made; in this way, the

Chapter 3: Configuration

Configuration Method

Description
“SFP B” line is held as the standby line. The “SFP B” line is held in the LINK state for testing and line verification, but does not actively carry user data. When a fault is detected on the active line, all customer traffic is switched to the “SFP B” port. Once the “A” port is no longer in a fault condition, data is resumed on that port.

NOTE
Revertive and Non-Revertive modes can only operate on the ports with SFPs, not the fixed copper ports.

3.5.2.10

Rebooting the Unit

To reboot the IE GIGA MC TX/SFP, type reboot from the main screen or the command menu.

3.5.2.11

Enabling/Disabling DHCP

To toggle DHCP on the IE GIGA MC TX/SFP between enable and disable, press D and then Y. Press the Space Bar once to return to the main screen without making any changes.

DHCP Disable (Static IP Addressing)

DHCP is disabled in the default configuration. Initially, modules are assigned a Static default IP Address of 10.10.10.10. Changes to the Static IP Address can be added manually through iView2 (iConfig view) or a Console session. The changes will be initiated following reboot of the module.

DHCP Enable (Dynamic IP Addressing)
If a DHCP server is present on the network and DHCP is enabled, the DHCP client will initiate a dialogue with the server during the boot up sequence. The server will then issue an IP address to the management card. Once the new IP address is received, the SNMP Management Module will reboot so that the new IP address will take effect. Refer to About Serial Port Configuration for more information about Enabling/Disabling DHCP.

When there is no DHCP server on the network, use the serial configuration to manually set the IP addresses.

When DHCP is enabled, the IP address (default 10.10.10.10 or a previously used IP address, or user-configured) is saved. When DHCP is disabled, the saved IP address will be reinstated and the device will reboot.

DHCP servers give out lease times: devices renew their leases based on the administrator-specified time. If a device cannot renew its lease, and the lease expires, the device will be given the IP address 10.10.10.10 and will reboot.

3.5.3.5 Bandwidth (bw) Displays settings for Bandwidth configuration.

Chapter 3: Configuration

SFP A/B Ports Ingress Bandwidth Limit (CIR)
Max Burst Allocation size (BA) Ingress Burst Allocation
Egress Traffic Shaping

Monitors the traffic entering the unit (ingress), discarding traffic that exceeds a fixed Committed Information Rate (CIR) plus Burst Allocation (BA). Frames are not held in queue, they either meet the bandwidth limits and are accepted into the unit or they are dropped.
The BA size is specified in bits; the # of bits above the bandwidth limit before packets are thrown away.
Bandwidth Limiting can be set at Ingress of each port individually by setting the MAX Bandwidth Limit in bits/Sec. and the BA in bits. Traffic in excess of the Bandwidth limit plus BA for any time interval will be dropped. This function utilizes an advanced “Leaky Token-Bucket” algorithm to provide typical resolution under 5% of the set values at all data rate and frames sizes.
Egress Traffic shaping actively controls the transmitter and hard limits the maximum frame rate that can be sent. Frames can be delayed in the internal buffers of the unit, waiting their turn to be sent. If the internal buffers are full, excess traffic will be dropped.

TX1/2 Ingress Bandwidth Limit (CIR)
Max Burst Allocation size (BA)

Monitors the traffic entering the unit (ingress), discarding traffic that exceeds a fixed Committed Information Rate (CIR) plus Burst Allocation (BA). Frames are not held in queue, they either meet the bandwidth limits and are accepted into the unit or they are dropped.
The BA size is specified in bits; the # of bits above the bandwidth limit before packets are thrown away.

Ingress Burst Allocation
Egress Traffic Shaping
OSI Level Used in Calculations (Open Systems Interconnect, referring to the seven layers for TCP/IP)

Bandwidth Limiting can be set at Ingress of each port individually by setting the MAX BW Limit in bits/Sec. and the BA in bits. Traffic in excess of the Bandwidth limit plus BA for any time interval will be dropped. This function utilizes an advanced “Leaky Token-Bucket” algorithm to provide typical resolution under 5% of the set values at all data rate and frames sizes.
Actively controls the transmitter and hard limits the maximum frame rate that can be sent. Frames can be delayed in the internal buffers of the unit, waiting their turn to be sent. If the internal buffers are full, excess traffic will be dropped. The Unit Rate Control can be used to alleviate this.
Choose Layer 1, 2 or 3 for the counter, this will determine how my bytes from the Ethernet frame are to be included in the calculations.

Layer 1: Layer 2: Layer 3:

Preamble + DA to CRC + IFG Frames DA to CRC Frames DA to CRC ­ 18 (- 4 if frame is tagged)

Explanations:

Unit Rate Control Enable/Disable

Preamble = 8 bytes

DA

= EtherNet Destination Address

CRC

= EtherNet Checksum

IFG

= 12 bytes

Allows the end user to globally configure all

Bandwidth settings when enabling Unit Rate Control

(Flow Control). If the END device connected to the

port also has Flow Control enabled, this will ensure

packets will not be dropped.

LGC340A-R2

Chapter 3: Configuration
OSI NOTES The Bandwidth Limit functions can be adjusted to only count the Layer 1, 2, or 3 portions of the physical line rate. Layer 1 is used to relate Bandwidth to the physical line rate where a 100BaseT Ethernet line can carry a MAX bandwidth of 100Mbps. Layer 2 may be more useful when the Ethernet Frame may be carried over several different physical protocols such as SONET or SDH. Only the bandwidth required by the Ethernet frame is counted, making this a more consistent number over different protocols. Layer 3 counting could be used when a relationship to the actual customer data or line payload is required. If a 10 Mbps customer file needs to be sent in one second, then a minimum bandwidth limit of 10Mbps would need to use Layer 3 counting to allow this.
It must be noted that only Layer 1 counting is not affected by the size of the Ethernet frame. At 64 byte Ethernet frames, the MAX bandwidth the line can support at Layer 2 is only 76.2% of the line rate. This maximum falls to 54.8% of the line rate when counting is further limited by only counting Layer 3 payload data.

Chapter 6: Troubleshooting

6. Troubleshooting
If a fiber connection cannot be established, perform the following to make sure that the fiber transceivers on the IE GIGA MC TX/SFP are not over/under driving the fiber receivers:
1. Make sure the fiber wavelength on both connected devices match (i.e. both are 1310 nm single-mode fiber).
2. Make sure the twisted-pair port speed on the IE GIGA MC TX/SFP matches that of the end devices connected to the IE GIGA MC TX/SFP Configure the IE GIGA MC TX/SFP and its link partner to Auto Negotiation or, if using Force mode, be sure speed and duplex match.
3. IE GIGA MC TX/SFP allows the end user to assign a VLAN tag to all management traffic (SNMP and telnet). It is important to understand that IF using telnet or iView2 to assign a VLAN tag to management traffic then as soon as this setting is saved the connectivity will be lost until the PC becomes a member of the VLAN which was assigned to management traffic.
If a VLAN tag has been assigned to management traffic and the end user cannot re-establish a connection to the device via iView2 or telnet, directly connect a PC to the device via the serial cable and review/modify the changes made (reference section on serial port config).

Chapter 8: Fiber Optic Cleaning Guidelines
8. Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to- diagnose problems in an installation.
2. Dust caps are installed at Black Box to ensure factory-clean optical devices. These protective caps should not be removed until the moment of connecting the fiber cable to the device. If you need to disconnect the fiber device, reinstall the protective dust caps.
3. Store spare caps in a dust-free environment such as a sealed plastic bag or box so that when reinstalled they do not introduce any contamination to the optics.
4. If you suspect that the optics have been contaminated, alternate between blasting with clean, dry, compressed air and flushing with methanol to remove particles of dirt.

Chapter 9: Electrostatic Discharge Precautions
9. Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in modules or stand alone units, containing electronic components. Always observe the following precautions when installing or handling these kinds of products.
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or component. If the wrist strap is not available, maintain grounded contact with the system unit throughout any procedure requiring ESD protection.
3. Hold the units by the edges; do not touch the electronic components or gold connectors.
4. After removal, always place the boards on a grounded, static-free surface, ESD pad or in a proper ESD bag. Do not slide the modules or stand alone units over any surface.
WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to accepted industry practices.
