Power to IP Phones

Ports and Power Supplies

Table 2-1 shows the number of IP phones that can be supported with the 1050W,

1300W, and 2500W power-enabled line cards on a Cisco Catalyst 6509 with the

Policy Feature Card (PFC).

External Patch Panel Power

If the switch does not have a power-enabled line card, or one is not available for

the switch being used, then a Cisco power patch panel (Figure 2-6) can be used.

The power patch panel can be inserted in the wiring closet between the Ethernet

switch and the Cisco IP Phone.

Figure 2-6 Cisco Power Patch Panel

The patch panel has a 250W power supply and draws its power from a 110 VAC

source. It can accommodate 48 ports and is capable of supplying power to each of

the 48 ports at 6.3W per Cisco IP Phone model 7960. We recommend an

uninterruptible power supply (UPS) for backup in the event of a power failure.
