Cable Specifications
The following cables are required to connect the Cisco SIP IP phone:
•RJ-11 for the handset connection
•RJ-45 jack for the LAN connection (labeled "10/100 SW").
•RJ-45 jack for a second 10Base-T compliant connection (labeled "10/100 PC").
•48-volt power connector. The diameter of the center pin in the phone power jack (Switchcraft 712A) is .1 inches (2.5 mm). The center pin is positive (+) voltage. The miniature power plug required to mate with the power jack on the phone is a Switchcraft 760 or equivalent.
Connections Specifications
The Cisco SIP IP phone has two RJ-45 ports that each support 10/100 Mbps half- or full-duplex connections to external devices—the network port and access port. You can use either Category 3 or 5 cabling for 10 Mpbs connections, but use Category 5 for 100 Mbps connections. On both the LAN-to-phone port (left RJ-45 port facing the back of the phone) and PC-to-phone port (right port), use full-duplex to avoid collisions. Use the LAN-to-phone port to connect the phone to the network a LAN-to-phone jack. Use the PC-to-phone port to connect a network device, such as a computer, to the phone.
