Installing and Removing Ethernet Switching Modules
Installing an Ethernet Switching Module
The C6800-32P10G-XL Ethernet module illustrations are shown here as examples; the same installation procedure applies to other modules.
That there is
enough clearance to accommodate any interface equipment, such as pluggable
transceivers, installed directly on the module ports. If possible, install
modules between empty slots that contain only module filler plates.
That you have
adequate cable guides installed on the chassis to accept the additional network
interface cables for the new module.
That the captive
installation screws are tightened on all modules installed in the chassis.
This is to
ensure that the EMI gaskets on all of the modules are fully compressed in order
to maximize the opening space for the new or replacement module. If the captive
installation screws are loose, the EMI gaskets on the installed modules will
push adjacent modules toward the open slot, reducing the opening size and
making it difficult to install the module.
What to Do Next
Removing an Ethernet Module
During this
procedure, wear grounding wrist straps to avoid ESD damage to the module.
Invisible laser
radiation may be emitted from disconnected fibers or connectors. Do not stare
into beams or view directly with optical instruments.
Statement

Caution
Warning
| Step 1 | Attach an ESD grounding strap to your wrist and to ground. | ||
| Step 2 | Disconnect any network interface cables attached to the module. | ||
| Step 3 | Verify that the
captive installation screws on all of the modules in the chassis are tight.
This step ensures that the space created by the removed module is maintained. If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, reducing the opening size and making it difficult to remove the module. | ||
| Step 4 | Loosen the two captive screws on the module. Make sure that the two captive screws are completely unscrewed from the chassis. | ||
| Step 5 | Place your thumbs on the left and right ejector levers and simultaneously rotate the levers outward to unseat the module from the backplane connector. | ||
| Step 6 | Grasp the front edge of the module and slide the module part of the way out of the slot. Place your other hand under the module to support the weight of the module. Do not touch the module circuitry. | ||
| Step 7 | Place the removed module on an antistatic mat or in an antistatic bag, or immediately reinstall it in another slot. | ||
| Step 8 | Perform one of
the following steps:
If the slot is to remain empty and is adjacent to a module, you must install a module filler plate (Cisco part numbers SLOTBLANK-09 or WS-X6K-SLOT-CVR-E) to maintain proper air flow through the chassis. Do not install a blank slot cover (Cisco part number WS-X6K-SLOT-CVR) over the unused slot.
|
Installing Transceivers and Module Connectors
Some Ethernet modules require that pluggable transceivers be installed in the module port sockets. These transceivers are normally shipped separately from the module and must be installed after the module is installed in the chassis slot.

Attaching Network Interface Cables
Attaching Optical Network Interface Cables
Caution | Do not remove the plugs from the transceiver optical bores or the fiber-optic cable until you are ready to connect the cable. The plugs protect the transceiver optical bores and cable from contamination. |
| Step 1 | Remove the dust plugs from the network interface cable optical connectors. Save the dust plugs for future use. |
| Step 2 | Immediately
inspect and clean the optical connector's fiber-optic end-faces.
|
| Step 3 | Remove the dust
plugs from the transceiver optical bores.
If you are using the LX/LH GBIC with MMF, you need to install a patch cord between the GBIC and the MMF cable. The Read-Only WDM GBIC (WDM-GBIC-REC=) has only one optical bore (receive). |
| Step 4 | Immediately attach the network interface cable optical connector to the transceiver. Follow these guidelines: |
Mode-Conditioning Patch Cord
When using the long-wavelength and long-haul (LX and LH) GBIC with 62.5-micron diameter multimode fiber (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.
When an unconditioned laser source designed for operation on single-mode optical fiber (SMF) is directly coupled to an MMF cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable. This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.
A mode-conditioning patch cord is required for 1000BASE-LX and LH applications over FDDI-grade, OM1, and OM2 fiber-cable types. Mode-conditioning patch cords should not be used for applications over OM3 fiber cable (laser-optimized fiber cable). For more information about mode-conditioning patch cords, see the Use of Mode Conditioning Patch Cables in Gigabit Ethernet and 10 Gigabit Ethernet Laser-Based Transmissions bulletin available on Cisco.com.

 Note | We recommend that you use the LX and LH GBIC and MMF with the patch cord for short link distances of 33 to 328 feet (10 to 100 meters) because not using the patch could result in an elevated bit error rate (BER). |
The patch cord is required to comply with IEEE standards. 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 and LH GBIC complies with the IEEE 802.3z standard for 1000BASE-LX.
Installing the Patch Cord
Warning | Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 |
To install the patch cord, perform these steps:
1. Plug the end of the patch cord labeled To Equipment into the GBIC. See Figure 1.
2. Plug the end labeled To Cable Plant into the patch panel. See Figure 1.
DETAILED STEPS
Connecting Transceivers to a Copper Network
Caution | To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair Category 5 cabling. |
| Step 1 | Insert the
network cable RJ-45 connector into the RJ-45 connector on the transceiver.
When connecting to a 1000BASE-T-compatible switch or repeater, use four-twisted-pair, crossover Category 5 cabling. |
| Step 2 | Insert the other end of the network cable into an RJ-45 connector on a 1000BASE-T-compatible target device. |
Verifying the Installation
Verifying Newly Installed Modules
Enter the show module or show port [modnum/port_num] privileged EXEC command.
This verifies that the system acknowledges the new modules and has brought them online.
Enter the ping host user EXEC command to ping a host and check connectivity.
If the host is unresponsive, check the IP address of the switch and default IP route, if appropriate.
