Network and Computer Port Pinouts

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

The Network port is the 10/100/1000 SW port on the Cisco Unified IP Phone.

The Computer (access) port is the 10/100/1000 PC port on the Cisco Unified IP Phone.
