100-240 VAC, 50-60 Hz, 0.5 A—when using the AC adapter
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)
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.
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).
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 Phone 7962G, 7942G, 7961G and 7941G; labeled 10/100/1000 SW on the Cisco Unified IP Phone 7961G-GE and 7941G-GE).
RJ-45 jack for a second 10/100BaseT compliant connection (labeled 10/100 PC on the Cisco Unified IP Phone 7962G, 7941G, 7961G and 7941G; labeled 10/100/1000 PC on the Cisco Unified IP Phone 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.
Network Port Connector
Table D-2 describes the network port connector pinouts.
