Detailed Product Description

2900 Series XL switch modules are high-performance, field-installable expansion cards that enable users to grow their networks, minimize network downtime, and migrate to new technologies as their needs change. The Catalyst 2900 XL modules support virtual LAN (VLAN) trunking with standards-based 802.1Q and Inter-Switch Link (ISL) protocols, enabling superior functionality for end-to-end network management.

Each Catalyst 2912MF XL, Catalyst 2916M XL, and Catalyst 2924M XL switch contains two slots and supports a broad range of expansion modules.

The Catalyst 2900 XL switch modules are the ideal solution for workgroups and individual users who need increased performance and expandability at an affordable price. The switch modules provide 10Base-T/100Base-TX, 100Base-FX, 1000Base-X (TX, SX, LX/LH), 1000Base-T, and Asynchronous Transfer Mode (ATM) connectivity to servers and network backbones. These ATM modules are ideal for deployment at the access layer in a campus environment, as an uplink to a high-speed ATM backbone. Deployment as a link on a metropolitan-area network or directly on a SONET/SDH ring is not recommended for this product.
