Cisco Systems, Inc. WS-X2922-XL-V Switch Module

The Cisco WS-X2922-XL-V Switch Module is a two-port 100BASE-FX fiber expansion card for Catalyst 2900 XL-series switches, adding two independent 100 Mbps fiber Ethernet ports to extend your LAN over fiber. Designed for installation in compatible 2900 XL chassis such as WS-C2912-XL, WS-C2924-XL, WS-C2924C-XL, WS-C2924M-XL, and WS-C2912MF-XL, it plugs into an available expansion slot and identifies itself with part number 800-04281-02, Revision A0 (WSX2922XLV). The module supports VLAN-enabled interswitch links via ISL and IEEE 802.1Q trunking, aligning with classic Layer-2 deployments that require VLAN isolation or trunked uplinks. Typical applications include fiber-based uplinks between access and distribution switches, adding 100BASE-FX fiber paths to existing 2900-series networks, or connecting servers and storage devices at 100 Mbps where copper would be impractical. By providing two dedicated 100BASE-FX ports, the WS-X2922-XL-V enables flexible fiber deployment and traffic segmentation within the Catalyst infrastructure.
