Catalyst 2900 Series XL

OVERVIEW

The Cisco Catalyst® 2900 series XL is a full line of 10/100 autosensing Fast Ethernet switches from the leader in networking that combines outstanding performance, ease of

use, and integrated Cisco IOS series XL includes ﬁve models, each with different port densities, conﬁguration options, andpricingtomeet a broad range of network design requirements. Availablein Standard and Enterprise Editions, the software embedded in Catalyst 2900 series XL switches is upgradeable so your investment is protected if your network grows or changes.

The 24-port Catalyst 2924M XL switch is an excellent aggregation device, as well as the perfect solution for providing dedicated 10- or 100-Mbps bandwidth to individual users. The 12-port Catalyst 2912MF XL switch is ideal for aggregating small and mid-sized campus networks over 100BaseFX ﬁber connections. The two versatile module slots of the Catalyst 2912MF XL and Catalyst 2924M XL provide expansion capabilities, higher-speed connectivity, and support for feature modules, allowing you the ﬂexibility to upgrade your network and preserve your initial investment. The 12-port Catalyst 2912 XL, 24-port Catalyst 2924 XL, and Catalyst 2924C XL switches are ideal for deliveringlow-cost, high-performance, and10- or 100-Mbps bandwidth to individual users and servers.

extended distance (up to 2 kilometers) with ﬁber-optic cabling. The Catalyst 2924M XL switch accepts 10BaseT/ 100BaseTX and 100BaseFX expansion modules today and a broader range of uplink modules in the future. All Catalyst 2900 XL products support the aggregation of multiple ports

via Fast EtherChannel bandwidth connections between switches, servers, and other key network stations.

High-Performance Desktop Connectivity (10/100 to the Desktop)

The Catalyst 2912 XL, Catalyst 2924 XL, Catalyst 2924C XL, and Catalyst 2924M XL can all be deployed as high-performance solutions to provide 10/100 bandwidth directly to the desktop. The Catalyst 2912 XL and Catalyst 2924 XL offer the lowest price per port in a ﬁxed conﬁguration. The Catalyst 2924C XL contains two 100BaseFX ports for networks that need to deploy high-performance 100-Mbps desktop connectivity over an

Enterprise Workgroup and Server Aggregation

The Catalyst 2924M XL will be deployed in wiring closets to aggregate workgroup networking devices such as Fast Ethernet hubs, Ethernet hubs and switches, and workgroup servers. Fast EtherChannel technology allows customers to logically ‘bond” multiple Fast Ethernet links, creating a high-capacity uplink to the corporate or campus backbone. Future high-speed modules will allow customers the ﬂexibility to upgrade their networks and preserve their initial investment in the Catalyst 2924M XL.

Workgroup and Server Aggregation for Small to Medium-Sized Networks

The24-port Catalyst2924M XL may be used as a ﬂexible, scalable,network backbonefor a small to medium-sized business (SMB). The switch is a effective solution for aggregating network resources and delivering dedicated 10- or 100-Mbps connectivity to individual users and workgroups in an SMB. Two high-speed uplink slots enable users to add up to eight additional 100BaseFX or 10BaseT/100BaseT ports.
