The 10/100 switch ports (see
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
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
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.
