48 VDC, 0.2 A—when using the in-line power over the network cable

Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE

The phone can receive power from IEEE 802.3af-compliant data switches (Class III)

The phone can be powered locally with a power adapter (Cisco part number CP-PWR-CUBE-3=) and the appropriate power cord (power requirements for the power adapter: 100-240 VAC, 50-60 Hz, 0.5 A)

Cables

Category 3/5/5e for 10-Mbps cables with 4 pairs
Category 5/5e for 100-Mbps cables with 4 pairs
Category 5e/6 for 1000-Mbps cables with 4 pairs

Note Cables have 4 pairs of wires for a total of 8 conductors.

Distance Requirements

As supported by the Ethernet Specification, it is assumed that the maximum cable length between each Cisco Unified IP Phone and the switch is 100 meters (330 feet).


Cable Specifications

RJ-9 jack (4-conductor) for handset and headset connection.

RJ-45 jack for the LAN 10/100BaseT connection

(labeled 10/100 SW on the Cisco Unified IP Phones 7962G, 7942G, 7961G and 7941G

labeled 10/100/1000 SW on the Cisco Unified IP Phones 7961G-GE and 7941G-GE).

RJ-45 jack for a second 10/100BaseT compliant connection

(labeled 10/100 PC on the Cisco Unified IP Phones 7962G, 7941G, 7961G and 7941G

labeled 10/100/1000 PC on the Cisco Unified IP Phones 7961G-GE and 7941G-GE).

48-volt power connector.

Network and Access Port Pinouts

Although both the network and access ports are used for network connectivity, they serve different purposes and have different port pinouts.

The network port is labeled 10/100 SW or 10/100/1000 SW on the Cisco Unified IP Phone.

The access port is labeled 10/100 PC or 10/100/1000 PC on the Cisco Unified IP Phone.
