AC/DC adapter port (DC48V) for power connector. For redundancy, you can use the AC adapter
even if you are using inline power from Cisco Catalyst switches. The Cisco IP 7960G/7940G
phone can share the power being used from the inline power and external power source. If either
the inline power or the external power goes down, the phone can switch entirely to the other power
source.

Power supply with AC plug.

Power cable with wall socket plug for connecting to power.

Network port (10 and 100 SW) RJ-45 to connect the phone to the network supporting 10- or
100-Mbps half- or full-duplex Ethernet connections to external devises. You can use either
Category 3 or Category 5 cabling for 10-Mpbs connections, but use Category 5 for 100-Mbps
connections. To avoid collisions, use full-duplex mode. You must use a straight-through cable on
this port. The phone can also obtain inline power from the Cisco Catalyst switch over this
connection.
