10/100 Ports
The 10/100 ports use RJ-45 connectors and twisted-pair cabling. The ports can
connect to these devices:
•
10BASE-T-compatible devices, such as workstations and hubs, through
standard RJ-45 connectors and two twisted-pair cabling. You can use
Category 3, 4, or 5 cabling.
•
100BASE-TX-compatible devices, such as high-speed workstations, servers,
hubs, routers, and other switches, through standard RJ-45 connectors and two
or four twisted-pair, Category 5 cabling.
Note
When connecting the switch to workstations, servers, and routers, be sure that
the cable is a twisted-pair straight-through cable. When connecting the switch
to hubs or other switches, use a twisted-pair crossover cable. Pinouts for the
cables are described in
Appendix B, “Connectors and Cables.”
The 10/100 ports can be explicitly set to operate in any combination of half
duplex, full duplex, 10 Mbps, or 100 Mbps. They can also be set for speed and
duplex autonegotiation, compliant with IEEE 802.3U. In all cases, the cable
length from a switch to an attached device cannot exceed 328 feet (100 meters).
