Connecting to the Network

The Cisco SIP IP phone has two RJ-45 ports that each support 10/100 Mbps half- or full-duplex Ethernet
connections to external devices—network port (labeled 10/100 SW) and access port (labeled 10/100
PC). You can use either Category 3 or 5 cabling for 10 Mpbs connections, but use Category 5 for 100
Mbps connections. On both the network port and access port, use full-duplex mode to avoid collisions.
Network Port (10/100 SW)
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 Catalyst switch over this connection. See the
"Connecting to Power" section on page 1-11
Access Port (10/100 PC)
Use the access port to connect a network device, such as a computer, to the phone. You must use a
straight-through cable on this port.
