Installing the Cisco IP Phone Models 7905G and 7912G

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.

Caution Do not cover or block the air vents on the back side of the Cisco IP Phone. Overheating can cause permanent damage to the unit.

Caution If you plan to power your phone locally (instead of receiving power through the Ethernet connection), use only a Cisco 48 volt power supply designed to work with a Cisco IP Phone.

Note Do not use hooded cables with the Cisco IP Phone models 7905G and 7912G because they can cause the phone to rock.

Procedure

Step 1 Use a Category 3 or 5 straight-through Ethernet cable to connect the 10BASET port on the Cisco IP Phone 7905G or the 10/100 SW port on the Cisco IP Phone 7912G to an Ethernet port.

Step 2 Connect the handset to the handset port.

Ensure that the end of the cord with the longer uncoiled section is connected to the body of the phone.

Step 3 Connect a Category 3 or 5 Ethernet cable to the 10/100 PC port on the back of the Cisco IP Phone 7912G (optional).

Use a crossover Ethernet cable to connect from the access port to another Ethernet device (such as a router or desktop computer) without using a hub. Otherwise, use a straight-through Ethernet cable.

The Cisco IP Phone 7905G does not have a 10/100 PC port.
