Catalyst 2900 Series XL Modules Hardware Installation Guide
78-5912-03
Chapter 1 Overview
Cabling Guidelines
The 10/100 ports are numbered 1X through 4X. The X indicates that the pins on
the port connector are internally crossed. If you are connecting to a device with
ports marked with an X, such as another switch or hub, use a crossover cable. If
you are connecting to devices with ports not marked with an X, such as a PC,
workstation, or server, use a straight-through cable.
For the connector pinouts and schematics, see the section “10/100 Module
Cabling” in Appendix B, “Connectors and Cables.”
Note Always observe the following general rules when connecting
devices: Use a straight-through cable to connect two ports when one
is designated with an X; use a crossover cable to connect two ports
when both are designated with an X.
100BaseFX Modules
The 100BaseFX ports use 50/125- or 62.5/125-micron multimode fiber-optic
cabling with duplex SC connectors. When set to run in full-duplex mode,
100BaseFX module ports can connect to compatible devices over distances of up
to 2 kilometers. For connector and schematic information, see Appendix B,
“Connectors and Cables.”

Installation
This chapter describes how to install, connect, and remove the Catalyst 2900
series 10/100, 100BaseFX, 1000BaseX, and 1000BaseT modules.
These modules can be installed while the switch is running and require no
configuration. A power-on self-test (POST) verifies that the module is running
properly before any packets are forwarded.
You can manage module ports the same way you manage fixed ports on the
switch. The web-based Switch Manager is a graphical user interface for
monitoring and controlling port features, and you can use the console port or
Telnet to access the Cisco IOS command-line interface.
Inspecting the Packing List
Before you install a 10/100, 100BaseFX, 1000BaseX, or 1000BaseT module,
ensure that the following items are included in the package:
• Catalyst 2900 series XL module
• Cisco Information Packet
• One CD-ROM containing the Flash image to upgrade the software for the
Catalyst 2900 series switch and the corresponding documentation.
If anything is missing, contact your Cisco Systems customer service
representative.

Avoiding Electrostatic Discharge
Before you install the module, ground yourself by touching a piece of metal to
avoid electrostatic discharge (ESD). You should also take the following
precautions to prevent damage to the board:
• Keep the module in its antistatic shielded bag until you are ready to install it.
• Handle the modules by the edges.
• Do not touch the components, pins, leads, or solder connections.
Installing a Module
The switch expansion slots are numbered 1 (left) and 2 (right). You can install
either of the modules into either slot. Blank faceplates on the Catalyst 2924M XL
switch cover the slots, as shown in Figure 2-1

Installing a Module
Caution When installing a 100BaseFX or 1000BaseX module, do not remove
the rubber plugs from the fiber-optic port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs
and caps protect the fiber-optic port and cable from contamination
and ambient light.
To remove a faceplate, follow these steps:
Step 1 Loosen the thumbscrews attaching the faceplate to the switch.
Step 2 Remove the faceplate from the switch, and store it for future use. Figure 2-1
shows a Catalyst 2924M XL switch with an empty expansion slot.

Step 3 Slide the module into the slot card-guides until you feel it touch the back of the
unit.
Step 4 Push the module firmly until it snaps into place.
Step 5 Tighten the thumbscrews on the module faceplate. The module begins running
POST when the thumbscrews are tightened.
Note The installation is not complete until the thumbscrews are
tightened.
Step 6 Ensure that the STATUS LED is green (module operational).
Step 7 If the module is not operational, reseat it. If the module still is not operational,
contact Cisco Systems for a replacement.
Handling a GBIC
Following are the Gigabit Interface Converter (GBIC) handling guidelines:
• GBICs are static sensitive. To prevent ESD damage, follow appropriate board
and component handling procedures.
• GBICs are dust sensitive. When storing a GBIC 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 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 a Module
Installing a GBIC
1000BaseX modules are shipped without GBICs installed.
Note GBICs are hot-swappable in 1000BaseX modules.
Caution Before you install the GBIC, ground yourself by touching a piece of
metal to avoid electrostatic discharge.
To install a GBIC, do the following:
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 a 1000BaseSX, 1000BaseLX/LH, or
ZX.
Step 3 Grip the sides of the GBIC with your thumb and forefinger, and insert it into the
slot on the front panel of the 1000BaseX module, as shown in Figure 2-2.

Using a Patch Cord with the GBICs
When using the LX/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 for link distances greater than 984 feet
(300 meters).
Note You must use the patch cord to comply with the IEEE 802.3z
standards. 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).

Default Settings for the 1000BaseX and 1000BaseT modules
The 1000BaseX and 1000BaseT modules have the same default settings as the
10/100 and 100BaseFX modules, with the following exception:
• port cost value
The Spanning Tree Protocol (STP) uses port path costs to determine which
port to select as a forwarding port. Ports attached to faster media (such as
1000BaseX) have lower numbers assigned to them by default, and ports
attached to slower media have higher numbers assigned. The default port cost
value for 1000BaseX and 1000BaseT ports is 4.
Removing a GBIC
To remove a GBIC, do the following:
Step 1 Disconnect the network fiber cable from the GBIC SC connector.
Step 2 Release the GBIC from the slot by simultaneously squeezing the two plastic tabs
(one on each side of the GBIC).
Step 3 Slide the GBIC out of the Gigabit Ethernet module slot. A flap drops down to
protect the Gigabit Ethernet module connector.
Step 4 If the GBIC is defective, dispose of the product.
Warning
Ultimate disposal of this product should be handled according to
all national laws and regulations.

Removing a Module
Removing a Module
To remove a module, follow these steps:
Step 1 Disconnect the cable from the module port.
Caution Catalyst 2900 series modules are “hot swappable,” provided that you
disconnect the cable from the module port before removing the
module from the switch. Removing the module before disconnecting
the module port cable(s) can result in a reboot or crash of the switch.
Step 2 Loosen the thumbscrews attaching the module faceplate to the switch.
Step 3 Remove the module by grasping the thumbscrews and pulling the module out of
the slot.
Caution Replace the rubber plugs in the fiber-optic connector on the module
and the rubber caps on the fiber-optic connector on the cable. The
plugs and caps protect the fiber-optic connectors from
contamination and ambient light.
Step 4 Replace the blank faceplate to cover the empty expansion slot.
Step 5 Tighten the thumbscrews on the faceplate.
Power-On Self-Test
When a module is inserted into the expansion slot, the port LEDs on the module
turn amber. After the module thumbscrews are tightened, the LEDs turn off and
then turn green. Starting from the left-most LED, the LEDs turn off in turn as
POST completes successfully. When all the LEDs are off, the LEDs blink green
and begin normal operations.
If a module fails POST, the expansion slot LED (1 or 2) on the switch turns amber.
All POST failures are fatal. Call Cisco Systems if a module fails POST.

Table 3-1 Common Problems and Their Solutions
Symptom Possible Causes Corrective Action
Port LED is
amber.
Thumbscrews have not been
tightened.
Tighten thumbscrews.
Spanning Tree Protocol is
checking for loops.
Wait for Spanning Tree Protocol to complete
its search. The LED turns green when
Spanning Tree Protocol completes its check.
Port is initializing, it was disabled
by management or an address
violation, or it was blocked by
Spanning Tree Protocol.
Use Visual Switch Manager or the IOS
command-line interface to check the status of
the port and to enable it.
Port LED is
alternating
between green and
amber.
Port is experiencing error frames.
This could be due to a duplex
mismatch caused by
autonegotiation, collisions, CRC
errors, or alignment errors.
Check the duplex settings on both devices.
Check the speed settings on both devices
except when using a gigabit Ethernet module.
You cannot change the speed on the gigabit
Ethernet modules. If one parameter is
manually set, manually set all of them, or set
both devices to autonegotiate speed and
duplex. See the Catalyst 2900 Series XL
