Chapter 1 Product Overview Front-Panel Description Table 1-1 Expansion Modules (continued) Module Type Model Number 1000BASE-T 1Ethernet Gigabit WS-X2932-XL WS-X2931-XL ATM WS-X2971-XL WS-X2972-XL WS-X2951-XL WS-X2961-XL 1. The Ethernet Gigabit module supports several Gigabit Interface Converter (GBIC) devices. For a complete list and the minimum software release required, refer to the Release Notes for the Catalyst 2900 Series XL and Catalyst 3500 Series XL Switches. These modules automatically configure themselves when you insert them in module slots and tighten the thumb screws. A power-on self-test (POST) verifies that the module is working properly before it starts forwarding packets. Note Modules WS-X2914-XL and WS-X2922-XL support 2048 MAC addresses. If you install one of these modules in a 2924M XL or Catalyst 2912MF XL switch (both supporting 8192 MAC addresses), the module fails POST. You can start the module by restarting that switch. After the restart, the switch address capacity is reduced to 2048 MAC addresses. Refer to the Catalyst 2900 Series XL Modules Installation Guide and the Catalyst 2900 Series XL ATM Modules Installation and Configuration Guide for detailed information on expansion modules for Catalyst 2900 series XL switches. LEDs 78-6461-04 You can use the switch LEDs to monitor switch activity and its performance. Figure 1-5, Figure 1-6, and Figure 1-7 show the location of the LEDs and the Mode button that you use to select a port mode. Changing a port mode changes the information provided by each port LED.
