Front-Panel Description Chapter 1 Product Overview 10/100 Ports The 10/100 switch ports (see Figure 1-2 and Figure 1-4) can connect to any compatible network device up to 328 feet (100 meters) away: • 10BASE-T-compatible devices, such as workstations, Cisco IP Phones, and hubs through standard RJ-45 connectors and Category 3, 4, or 5 cabling • 100BASE-TX-compatible devices, such as high-speed workstations, Cisco IP Phones, servers, hubs, routers, and other switches through standard RJ-45 connectors and Category 5 cabling Note A Category 5 cable is required for 100BASE-TX traffic. A port operating at 10BASE-T can use Category 3 and 4 cables. When connecting the switch to workstations, servers, routers, and Cisco IP Phones, be sure that the cable is a straight-through, twisted-pair cable. When connecting the switch to switches or hubs, use a crossover cable. Pinouts for the cables are described in Appendix B, "Connectors and Cable Specifications." The 10/100 switch ports can be explicitly set to operate in any combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. These ports also can be set for speed and duplex autonegotiation, compliant with IEEE 802.3U. When set for autonegotiation, the port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best connection (that is, the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly. The 10/100 ports on the Catalyst 2900 XL switches provide protocol support for Cisco IP Phones and per-port priority override. Refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide for more information about these features. Cisco IP Phones-connected to the 10/100 port-must be connected to an AC power source. Unlike the 3524-PWR XL switch, the Catalyst 2900 XL switches do not provide inline power. For more info on the Catalyst 3524-PWR XL switch, refer to the Catalyst 3500 Series XL Hardware Installation Guide. Catalyst 2900 Series XL Hardware Installation Guide 1-6 78-6461-04
