Cisco 7975G Installation Guide

Network and Access Ports
The back of the Cisco Unified IP Phones includes these ports:
•
Network port: Labeled 10/100 SW on Cisco Unified IP Phones 7970G, 7965G, and 7945G, and
10/100/1000 SW on the Cisco Unified IP Phones 7975G and 7971G-GE.
•
Access port: Labeled 10/100 PC on Cisco Unified IP Phones 7970G, 7965G, and 7945G, and 10/100/1000
SW on the Cisco Unified IP Phones 7975G and 7971G-GE.
Each port supports 10/100 or 10/100/1000 Mbps half- or full-duplex connections to external devices.
•
For the Cisco Unified IP Phones 7975G, 7971G-GE, and 7970G, you can use either Category 3 or 5
cabling for 10 Mbps connections, but you must use Category 5 for 100 and 1000 Mbps connections (the
Cisco Unified IP Phone 7970G does not support 1000 Mbps).
•
For the Cisco Unified IP Phones 7965G and 7945G, you can use either Category 3, 5, 5e, or 6 cabling
for 10 Mbps connections, but you must use Category 5, 5e, or 6 for 100 Mbps connections.
Use the SW 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 a switch over this connection. See Cisco Unified IP Phone
Power for details.
Use the PC access port to connect a network device, such as a computer, to the phone. You must use a
straight-through cable on this port.
Handset
The handset is designed especially for use with a Cisco Unified IP Phone. The handset includes a light strip
to indicate incoming calls and voice messages.
To connect a handset to the Cisco Unified IP Phones 7975G, 7965G, or 7945G, plug the cable into the handset
and into the Handset port on the back of the phone.
To connect a handset to the Cisco Unified IP Phones 7971G-GE or 7970G, remove the hookswitch clip from
the cradle area, as shown in the following figure. Then plug the cable into the handset and into the Handset
port on the back of the phone.
