Connecting to the Network

The Cisco IP Phone 7912G has two RJ-45 ports labelled “network” and “access.” The Cisco IP Phone models 7902G/7905G have one RJ-45 port. Each port supports 10/100 Mbps half- or full-duplex connections to external devices. You can use either Category 3 or 5 cabling for 10-Mbps connections, but you must use Category 5 for 100 Mbps connections. On both the network port and access port, use full-duplex mode to avoid collisions.

See Figure 3-1 for the connection ports available on the back of the Cisco IP Phone models 7902G/7905G. See Figure 3-2for the connection ports available on the back of the Cisco IP Phone 7912G

Using the Network Port

Use the network port to connect the phone to the network. You must use a straight-through cable on this port. The phone can also obtain inline power from the Cisco Catalyst switch over this connection. See the “Providing Power to the Cisco IP Phone” section on page 2-9for details.
