Network and Access Ports
The back of the Cisco Unified IP Phone 7912G has two RJ-45 ports. The network
port is labelled “10/100SW” and the access port is labeled “10/100PC.” The back
of the Cisco Unified IP Phone 7905G has one RJ-45 network port.
The two ports on the Cisco Unified IP Phone 7912G each support 10/100 Mbps
half- or full-duplex connections to external devices. The speed and connection
type are set through auto-negotiation. The single port on the Cisco Unified IP
Phone 7905G supports 10 Mbps half-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.
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 Unified IP Phone” section on page 2-9 for details.
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.
