Installation

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:

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:

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

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.


Figure 2-1: Catalyst 2924M XL Switch with an Empty Expansion Slot


After you have removed the faceplate, follow these steps to install a module in the empty expansion slot.

Warning Class 1 laser product.
Warning Avoid exposure to the laser beam.

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:

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.

Note GBICs are keyed to prevent incorrect insertion.
Warning Class 1 laser product.
Warning Avoid exposure to the laser beam.

Step 4 When you are ready to attach the network interface fiber-optic cable, remove the plug from the GBIC, and save it for future use.

Connecting to Module Ports

Insert a connector according to the type of module (100BaseFX, 10/100/1000BaseT, or 1000BaseX), as follows:

Insert the RJ-45 connector until it snaps into place, as shown in Figure 2-3.
Remove the rubber plugs from the fiber-optic port on the module and store them for future use. Insert the connector in the fiber-optic receptacle, as shown in Figure 2-5.
Note The port status LED is amber while Spanning Tree Protocol discovers the topology and searches for loops. This takes about 30 seconds. The port status LED then turns green.

Note Always use a straight-through cable when connecting to a PC, server, or workstation. Use a crossover cable to connect to another switch or hub. See the section "10/100 Module Cabling" in "Connectors and Cables."

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).

Patch Cord Configuration Example

Following is a typical configuration example:


Figure 2-6: Patch Cord Example


Installing the Patch Cord

Figure 2-7 shows the connectors on the patch cord. Connect the end of the patch cord labeled "To Equipment" into the GBIC. Connect 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 2-7: Patch Cord Cabling


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:

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

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.

Note If you power up a Catalyst 2912MF XL, Catalyst 2916M XL, or Catalyst 2924M XL switch with modules installed, the module ports are the last to run POST.
