The Catalyst 2900 series XL switches are workgroup Ethernet switches that supply autosensing 10BaseT or 100BaseT connections on all ports. These switches-also referred to as the Catalyst 2900 series-can be deployed as backbone switches aggregating 100BaseT traffic from other switches and hubs or in mixed configurations connecting hubs, switches, servers, and desktops.
The Catalyst 2924M XL and the Catalyst 2912MF XL models have two high-speed expansion slots for the Catalyst 2900 series XL hot-swappable modules. Each module port is internally switched to all other Catalyst switch ports and is managed through the switch management interfaces.
The Catalyst 2900 series XL modules automatically configure themselves when you insert them in expansion slots and tighten the thumb screws. A power-on self-test (POST) verifies that the module is working properly before it starts forwarding packets.
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, which support 8192 MAC addresses, the module will fail POST. You can start the module by restarting the switch with the module installed. After the restart, the addressing capacity of the switch is reduced to 2048 MAC addresses.
Modules WS-X2914-XL-V, WS-X2922-XL-V, and WS-X2924-XL-V support 8192 MAC addresses. If you install one of these modules in a Catalyst 2916M XL model, which supports 2048 MAC addresses, the module reduces its address capacity to 2048 MAC addresses.
