Gigabit Interface Converters

A gigabit interface converter (GBIC) (see Figure 3) is a hot-swappable input/output (transceiver) device that plugs into a module's Gigabit Ethernet port, linking the port with the fiber-optic network. The following GBIC types are supported:


Figure 3   Gigabit Interface Converter


Note      Cisco 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard.

Note      Due to interoperability issues, Cisco does not support GBICs purchased from third-party vendors.

For GBIC installation information, refer to the "GBIC Handling Guidelines and Installation" section.

For GBIC cabling distance information, refer to the "GBIC Cabling Distances" section.

Safety Recommendations

Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement.

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the appendix "Translated Safety Warnings" in the Catalyst 5000 Series Module Installation Guide.

Use the following guidelines to ensure your safety and protect the equipment. This list does not include all potentially hazardous situations during installation, so be alert.

Note      Power supplies in the Catalyst 5002 switch do not have on/off switches.

Only trained and qualified personnel should install or replace this equipment.
  • Always turn all power supplies off (the position marker zero), and unplug all power cords before installing or removing a chassis.
  • Keep the chassis area clear and free of dust during and after installation.
  • Keep tools and chassis components off the floor and away from foot traffic.
  • Avoid wearing jewelry and securely fasten any loose clothing that could get caught in the chassis.
Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.
Ultimate disposal of this product should be handled according to all national laws and regulations.

Basic Electrical Safety Guidelines

When working with electrical equipment, exercise these basic safety guidelines:

  • Never install equipment that appears to be damaged.
  • Locate the emergency power-off switch for the room in which you are working before beginning any procedures that require access to the chassis interior.
  • Disconnect all power and external cables before installing or removing a chassis.
  • Do not work alone when potentially hazardous conditions exist.
  • Never assume that power has been disconnected from a circuit; always check.
  • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
  • Examine your work area carefully for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Do not work on the system or connect or disconnect cables during periods of lightning activity.

Telephone Wiring and Network Cabling Safety Rules

Use the following safety rules when working with any equipment that is disconnected from a power source but still connected to telephone wiring or other network cabling:

  • Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
  • Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
  • Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic boards or components are improperly handled. ESD can result in complete or intermittent failures of electronic components.

Guidelines for preventing ESD damage are as follows:

  • Always use an antistatic wrist or ankle strap and ensure that it makes good skin contact.
  • If you use the wrist strap with an alligator clip, connect the alligator clip to one of the captive installation screws on the chassis, an installed module, or a power supply. If you use the wrist strap with a banana-plug connector, insert the banana-plug connector into the grounding receptacle on the rear of the chassis.
  • Handle supervisor engine modules and switching modules by the metal carrier edges only; the metal carriers have electromagnetic interference (EMI) shielding. Never touch the printed circuit boards or connector pins.
  • After removing a module, place it component-side up on an antistatic surface or in a static-shielding bag. If you plan to return the module to the factory, immediately place it in a static-shielding bag.
  • Avoid contact between the modules and clothing; the wrist strap protects the module from ESD voltages on the body, but ESD voltages on clothing can still cause damage.
  • Handle modules without metal carriers by the edges only.
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Installation and Configuration

All Catalyst 5000 series switches support hot swapping, which lets you install, remove, replace, and rearrange switching modules without turning off the system power. When the system detects that a switching module has been installed or removed, it runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.

Only trained and qualified personnel should install or replace this equipment.
Invisible laser radiation can be emitted from the aperture ports of the single-mode products when no fiber-optic cable is connected. Avoid exposure and do not stare into open apertures. This product meets the Class 1 Laser Emission Requirement.

Port Availability Restrictions for the Gigabit Ethernet Switching Module (WS-X5403)

Depending on the system and placement of the Gigabit Ethernet switching module in the system's backplane, not all of the module ports may be active. Table 6 lists the Catalyst 5000 series switches and the Gigabit Ethernet switching-module ports that are available when the module is installed in that switch.

Note      The use of the Gigabit EtherChannel switching module in Catalyst 5000 series switches using Supervisor Engine I or II is supported with Gigabit EtherChannel switching module software release 4.3(1) when used with supervisor engine software release 4.3(1).

Tools Required

You need a flat-blade screwdriver to remove any filler (blank) switching modules and to tighten the captive installation screws that secure the modules in their slots. Whenever you handle switching modules, you should use a wrist strap or other grounding device to prevent ESD damage. See the "Preventing Electrostatic Discharge Damage" section.

Removing Switching Modules

To remove a switching module from a Catalyst 5000 series switch, perform these steps:

During this procedure, wear grounding wrist straps to avoid ESD damage to the module. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
To prevent ESD damage, handle switching modules by the carrier edges only.
Step 1   Disconnect any network interface cables attached to the ports on the switching module you intend to remove.

Step 2   Loosen the captive installation screws, as shown in Figure 4.


Figure 4   Ejector Levers and Captive Installation Screws


Step 3   Place your thumbs on the left and right ejector levers and simultaneously pull the levers outward to release the module from the backplane connector. Figure 4 shows a close-up of the right ejector lever.

Step 4   Grasp the switching module with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.

Step 5   Carefully pull the switching module straight out of the slot, keeping one hand under the carrier to guide it.

Step 6   Place the switching module on an antistatic mat or antistatic foam, or immediately install it in another slot.

Step 7   If the slot is to remain empty, install a switching-module filler plate (part number 800-00292-01) to keep dust out of the chassis and to allow airflow through the switching-module compartment.

Always install a switching-module filler plate in empty switching module slots to allow cool air to flow across the modules.

Installing the Gigabit Ethernet Switching Module (WS-X5403)

To install the Gigabit Ethernet switching module (WS-X5403) in a Catalyst 5000 series switch, perform these steps:

During this procedure, wear grounding wrist straps to avoid ESD damage to the module. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
To prevent ESD damage, handle switching modules by the carrier edges only. Also, when removing or inserting a module, always wear an ESD wrist strap connected to the Catalyst 5000 series switch ESD wrist strap connector.
Step 1   Take the necessary precautions to prevent ESD damage, as described in the section "Preventing Electrostatic Discharge Damage."

Step 2   Choose a slot for the new switching module. See Table 6 for restrictions. Ensure that you have enough clearance for any interface equipment that you will connect directly to the switching module ports. If possible, place switching modules between empty slots that contain only switching-module filler plates.

Step 3   Loosen the captive installation screws securing the switching-module filler plate (or the existing switching module) to the desired slot.

Step 4   Remove the switching-module filler plate (or the existing switching module). Save the switching-module filler plate for future use.

Note If you are removing an existing switching module, place one hand carefully under the carrier to support the switching module as you slide it out of the chassis. Place the removed module in an antistatic bag or on an antistatic surface.

Step 5   To install the new module, hold the switching-module front panel with one hand, and place your other hand under the carrier to support the switching module. Do not touch the printed circuit boards or connector pins.

Step 6   Align the edges of the switching-module carrier with the slot guides on the sides of the switch chassis as shown in Figure 5.

Note Use the same procedure for all the Catalyst 5000 series switches.


Figure 5   Installing the Gigabit Ethernet Switching Module in the Chassis


Step 7   Pivot the two module ejector levers out away from the faceplate as shown in Figure 5.

Step 8   Carefully slide the switching module into the slot until the notches on both ejector levers engage the chassis sides.

Step 9   Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers, as shown in Figure 6, to fully seat the switching module in the backplane connector.


Figure 6   Module Ejector Lever Operation


Always use the ejector levers when installing or removing switching modules. A module that is partially seated in the backplane can cause the system to halt and subsequently crash.

Note If you perform a hot swap, the console displays the message "Module n has been inserted." This message also appears if you are connected to the Catalyst 5000 series switch through a Telnet session.

Step 10   Use a screwdriver to tighten the captive installation screws on each end of the switching-module faceplate.

Step 11   If not already done, install the GBICs. See the "GBIC Handling Guidelines and Installation" section for details.

Note If you are connecting the 1000BaseLX/LH (WS-X5486) GBICs to an MMF network, you must install a mode-conditioning patch cord. See the "Mode-Conditioning Patch Cord" section for details.

Step 12   Attach network interface cables or other devices to the interface ports. See the "Connecting GBICs to the Gigabit Ethernet and Gigabit EtherChannel Ports" section for details.

Step 13   Check the status of the module. See the "Checking the Interface Status" section for details.

Installing the Gigabit EtherChannel Switching Module (WS-X5410)

To install the Gigabit EtherChannel switching module (WS-X5410), perform these steps:

During this procedure, wear grounding wrist straps to avoid ESD damage to the module. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
To prevent ESD damage, handle switching modules by the carrier edges only. Also, when removing or inserting a module, always wear an ESD wrist strap connected to the Catalyst 5000 series switch ESD wrist strap connector.
Tip 

Because of the GEM's two-slot design, this module is more difficult to insert and remove than single-slot modules. Use care when inserting and removing the Gigabit EtherChannel switching module. Insertion and removal should be done in a single, smooth motion.

Step 1   Take the necessary precautions to prevent ESD damage, as described in the section "Preventing Electrostatic Discharge Damage" section.

Step 2   Choose a slot for the new switching module. See Table 7 for restrictions. Ensure that you have enough clearance for any interface equipment that you will connect directly to the switching-module ports. If possible, place switching modules between empty slots that contain only switching-module filler plates.

Note The Gigabit EtherChannel switching module requires two empty slots.

Step 3   Loosen the captive installation screws securing the switching-module filler plates (or the existing switching modules) to the desired slots.

Step 4   Remove the switching-module filler plates (or the existing switching modules). Save the switching-module filler plates for future use.

Note If you are removing an existing switching module, see the "Removing Switching Modules" section.

Step 5   To install the new module, hold the switching-module front panel with one hand, and place your other hand under the carrier to support the switching module. Do not touch the printed circuit boards or connector pins.

Step 6   Align the edges of the switching-module carrier with the slot guides on the sides of the switch chassis, as shown in Figure 7.

Note Align the edges of the switching-module carrier with the slot guides in the lower of the two empty slots.

Step 13   Check the status of the module. See the "Checking the Interface Status" section for details.

GBIC Handling Guidelines and Installation

This section describes how to install, remove, and maintain GBICs.

GBIC Handling Guidelines

Follow these GBIC handling guidelines:

  • GBICs are static sensitive. To prevent ESD, see the "Preventing Electrostatic Discharge Damage" section.
  • GBICs are dust sensitive. When the GBIC is stored or when a fiber-optic cable is not plugged in, always keep plugs in the GBIC optical bores.
  • The most common source of contaminants in the optical bores is from debris picked up on the ferrules of the optical connectors. Use an alcohol swab or Kim-Wipe to clean the ferrules of the optical connector.

Installing GBICs

To prevent premature failure of the GBIC, do not remove or insert the GBIC unnecessarily. GBICs have a lifetime of 100 to 500 removals and insertions.
When removing or inserting a GBIC, always wear an ESD wrist strap connected to the Catalyst 5000 series switch ESD wrist strap connector.

Note      GBICs are hot-swappable in the Gigabit Ethernet and Gigabit EtherChannel switching modules.

To install a GBIC, perform these steps:

Step 1   Remove the GBIC from its protective packaging.

Step 2   Verify that the GBIC is the correct type for your network by checking the part number. The number indicates whether it is 1000BaseSX, 1000BaseLX/LH, or 1000BaseZX.

Note Three GBIC styles are available: WS-G5484 (1000BaseSX), WS-G5486 (1000BaseLX/LH), and WS-G5487 (1000BaseZX).

Step 3   Grip the sides of the GBIC with your thumb and forefinger; insert the GBIC into the slot on the front of the Gigabit Ethernet or Gigabit EtherChannel switching module (see Figure 9). GBICs are keyed to prevent incorrect insertion.

Note A maximum of 6 1000BaseZX GBICs are supported in a switch chassis.


Figure 9   Installing a GBIC in a Gigabit Ethernet Switching Module


Step 4   Slide the GBIC through the flap covering the slot opening. Continue sliding the GBIC into the slot until you hear a click. The click indicates that the GBIC is locked in the slot.

Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber-optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.

Step 5   When you are ready to attach the fiber-optic cable, remove the plugs from the GBIC. Save the plug for future use.

Note If you are connecting the 1000BaseLX/LH (WS-X5486) GBICs to an MMF network, you must install a mode-conditioning patch cord. See the "Mode-Conditioning Patch Cord" section for details.

Class 1 laser product.

Connecting GBICs to the Gigabit Ethernet and Gigabit EtherChannel Ports

To connect GBICs to the Gigabit Ethernet or Gigabit EtherChannel ports, perform these steps:

Step 1   Remove the plugs from the GBIC optical bores; store them for future use.

Step 2   Remove the plugs from the SC connector (see Figure 10) on the fiber-optic cable. Insert the connector into the GBIC.

Note When you plug the SC connector into the GBIC, make sure that both the tx (transmit) and rx (receive) fiber-optic cables are fully inserted into the SC connector.

Note If you are using the LX/LH GBIC with MMF, you need to install a patch cord between the GBIC and the MMF cable. See the "Mode-Conditioning Patch Cord" section for details.

Do not remove the plugs from the GBIC optical bores or the fiber-optic cable until you are ready to connect the cable. The plugs protect the GBIC optical bores and cable from contamination.

Figure 10   SC Connector


Removing GBICs

To remove a GBIC, perform these steps:

Step 1   Disconnect the fiber-optic cable from the GBIC SC-type connector.

Step 2   Release the GBIC from the slot by simultaneously squeezing the plastic tabs (see Figure 11).


Figure 11   Removing a GBIC in a Gigabit Ethernet Switching Module


Step 3   Slide the GBIC out of the slot.

Step 4   Install the plugs in the GBIC optical bores, and place the GBIC in protective packaging.

Mode-Conditioning Patch Cord

When using the 1000BaseLX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord (Cisco product number CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on both the transmit and receive ends of the link. The patch cord is required for link distances greater than 984 feet (300 meters).

Note      For link spans of less than 300 meters, the patch cord can be omitted; however, using the LX/LH GBIC with MMF and no patch cord for very short link distances (tens of meters) is not recommended. The result could be an elevated bit error rate (BER).

Note      The patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable due to a problem in the center of some fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center by using the patch cord. At the output of the patch cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BaseLX. For a detailed description of this problem, refer to Appendix C, "Differential Mode Delay," in the Catalyst 5000 Series Supervisor Engine Installation Guide.

Note      Cisco Gigabit Ethernet products have been tested and evaluated to comply with the standards listed in the "Standards Compliance" section. Equivalent cables should also meet these standards.

Patch Cord Configuration Example

Figure 12 shows a typical configuration using the patch cord.


Figure 12   Patch Cord Configuration


Installing the Patch Cord

Plug the end of the patch cord labeled "To Equipment" into the GBIC (see Figure 13). Plug the end labeled "To Cable Plant" into the patch panel. The patch cord is 9.84 feet (3 meters) long and has duplex SC-male connectors at each end.


Figure 13   Patch Cord Installation


Checking the Interface Status

Check the status of the interfaces as follows:

  • Ensure that the Status LED cycles from orange to green when you apply power to the module.
  • If you perform a hot swap, the console displays the message "Module n has been inserted." This message also appears if you are connected to the Catalyst 5000 series switch through a Telnet session.
  • If this installation is for a replacement switching module, enter the show module or show port [mod_num/port_num] command to verify that the system has acknowledged the new interfaces and brought them up.

Configuring Flow Control on the Gigabit Ethernet Switching Module (WS-X5403)

The Gigabit Ethernet switching modules use flow control, which inhibits packet transmission to the Gigabit Ethernet module for a period of time. If the Gigabit Ethernet switching module's receive buffer becomes full, the module transmits a "pause" packet that tells remote devices to delay sending more packets for a specified period of time. The Gigabit Ethernet switching module can also receive "pause" packets from other devices.

To configure flow control, enter the set port flowcontrol {receive | send} mod_num/port_num {off | on | desired} command. Table 10 lists the flow-control tasks and commands.

Table 10   Gigabit Ethernet set port flowcontrol Commands

Task Command

Configuring Flow Control on the Gigabit EtherChannel Switching Module (WS-X5410)

Ports can be characterized by their ability to generate and respond to flow control frames (pause frames) as well as the pause behavior they require of their link partner.

The Gigabit EtherChannel module's Gigabit Ethernet ports respond to received pause frames. Upon configuration, these ports advertise a pause capability. The ports at the two ends of the link negotiate a mutually acceptable flow-control configuration.

A pause frame is never generated by the Gigabit EtherChannel module's Gigabit Ethernet ports.

In all cases, pause frames received on the module are processed internally and are not switched through the system.

To configure flow-control, enter the set port flowcontrol {receive | send} [mod_num/port_num] {off | on | desired} command. Table 12 lists the flow-control tasks and commands.

Table 12   Gigabit EtherChannel set port flowcontrol Commands

Task Command

Causes the local port to advertise that it will send flow-control frames1.

set port flowcontrol send mod_num/port_num on

Causes the local port to advertise that it will send flow-control frames if the attached device elects to receive them1 (default).

set port flowcontrol send mod_num/port_num desired

Turns off a local port's ability to send flow-control packets to a remote device.

set port flowcontrol send mod_num/port_num off

Requires a local port to be flow controlled by a remote device.

set port flowcontrol receive mod_num/port_num on

Causes the local port to operate with an attached device that is required to send flow-control packets or with an attached device that is not required to but may send flow-control packets.

set port flowcontrol receive mod_num/port_num desired

Turns off an attached device's ability to send flow-control packets to a local port (default).

set port flowcontrol receive mod_num/port_num off

1Even though the GEM never sends flow-control frames, this configuration option is useful if the attached device refuses to complete negotiation unless the local device advertises that it will send flow-control frames. For cases where the attached device is willing to accept flow-control frames, there is no adverse effect in advertising to that attached device that the local device intends to send them.

This example shows how to turn transmit flow control on:

Console> (enable) set port flowcontrol send 5/1 on
Port 5/1 flow control send administration status set to on
(port will send flowcontrol to far end)

Configuring Port Negotiation on the Gigabit EtherChannel Switching Module (WS-X5410)

Autonegotiation with Gigabit Ethernet behaves differently than autonegotiation with Ethernet or Fast Ethernet. To avoid link configuration problems, we recommend that you read and understand the information in this section and the information in the "Configuring Flow Control on the Gigabit Ethernet Switching Module (WS-X5403)" section.

Unlike 10/100 Fast Ethernet ports, autonegotiation with Gigabit Ethernet does not involve negotiating port speed. You cannot disable autonegotiation on Gigabit Ethernet ports by setting the port speed and duplex state. With Gigabit Ethernet, the link negotiation protocol is used to exchange flow-control behavior, remote fault information, and duplex information (even though the Catalyst 5000 series gigabit ports only support full-duplex operation). In Gigabit Ethernet, you can control whether the link negotiation protocol runs with the set port negotiation command.

Table 14 shows the four possible autonegotiation configurations for a link and the resulting link status for each configuration.

1Refers to the GEM's front panel port.

2Refers to the remote port at the other end of the gigabit link.

Both ends of the link must have the same setting. The link will not come up if the two ends of the link are set inconsistently (link negotiation enabled on one end and disabled on the other).

The link negotiation protocol is enabled by default. To enable or disable the link negotiation protocol on a port, perform this task:

Task Command

Enable or disable link negotiation protocol.

set port negotiation mod_num/port_num {enable | disable}

This example shows how to turn link negotiation off:

Console> (enable) set port negotiation 5/1 disable
Port 5/1 negotiation disabled.
Console> (enable)

To display the link negotiation protocol setting for the specified port, perform this task:

Task Command

Display the link negotiation protocol setting.
