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-TcanuseCategory3and4cables.
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.
