Connecting to the Network
The Cisco IP Phone 7912G has two RJ-45 ports labelled “10/100 SW” and
“10/100 PC.” Each port supports 10/100 Mbps half- or full-duplex connections to
external devices. The Cisco IP Phone 7905G has one RJ-45 port labeled
“10 BASET.” This port supports 10 Mbps half- or full-duplex connections to
external devices. You can use Category 3 or 5 cabling for 10-Mbps connections,
but you must use Category 5 cabling for 100 Mbps connections. Cisco
recommends that you use full-duplex mode on all ports (set at the switch) to avoid
collisions.
Use the 10BASET port on the Cisco IP Phone 7905G or the 10/100 SW port on
the Cisco IP Phone 7912G to connect a phone to the network. You must use a
straight-through cable on these ports. A phone can also obtain inline power over
these connections.
Use the 10/100 PC port on the Cisco IP Phone 7912G to connect a network device,
such as a computer, to the phone. You must use a straight-through cable on this
port.
