We have a 4500 with a Polycom 560 phone what will not power up with inline power. I have confirmed all the power settings and am not able to figrue out why this phone will not power on with POE.

Hi
That card only supports Cisco Pre-Standard PoE.
:
----------------------------------
IEEE 802.3af
Although the IEEE draft for power over Ethernet standards are not yet fully defined, the Cisco Catalyst 4006 chassis, auxiliary power shelf, and PEM are ready to support delivery of up to 15.4 watts per Ethernet port. New inline power line cards supporting both the IEEE 802.3af standard and Cisco inline power implementation will be available when the standard is ratified. For IEEE 802.3af compliance, an existing Cisco 48-port 10/100 Inline Power line card (part number WS-X4148-RJ45V) must be replaced with a new IEEE 802.3af-compliant line card.
-----------------------------------
Basically for non-Cisco devices (unless they claim to support Cisco pre standard PoE) you need a standards based 802.3af card. This means replacing your line card.
If you just have this one device or a small number power bricks may be a cheaper solution.

Any idea what blade that would be?
