Cisco Catalyst 2900 LRE XL switches (12 and 24 ports) are based on the Cisco Catalyst 2900 Series XL 3.2-Gbps switch architecture, and include all Enterprise-class features (all ports) available in Catalyst 2900 XL switches. Now, service providers can use the industry-leading Catalyst switch platform to address a broad range of wiring environments beyond Category 5 cabling.The Catalyst 2924 LRE XL has 24 Long-Reach Ethernet ports and four 10/100 Ethernet ports. This switch is one rack-unit (1RU) high, 13-inches deep, and can be either mounted on a wall or placed on a rack. In addition, Cisco LRE switches feature integrated LRE technology, which means that they do not require an external modem pool. The result is a compact, cost-effective form factor that allows service providers and building owners to build high densities with a minimum footprint.
