PoE problem with 3560-48 port

I am trying to power a door entry system which is 802.3af compliant (clas 3) from a 48 port 3560. It works on a 24 port version and on an HP switch but it will not work with the 48 port variant. The error log says "power Imax error". Looking at the documentation, although the switch cannot support all 48 ports at the full 15.4W, it should be able to intelligently manage power delivery to support up to 24 devices (I only need it to support 1), but this is not happening. Does anyone have any thoughts on this problem?

Thank you.


Re: PoE problem with 3560-48 port

The cause of this Message is output in the following condition.

1. Either IEEE 802.3af power device or Cisco power device is detected.

2. Power is given to the device, but link is not up with (5 or 10 seconds), and power thenwill be removed and this error message is generated.

These features have been added to Cisco IOS Release 12.1(19)EA1c .

Ability to provide power to connected Cisco prestandard and IEEE 802.3af-compliant powered devices from all Catalyst3750-24PS, 3750-48PS, 3560-24PS, and 3560-48PS switch 10/100 Ethernet ports if the switch detects that there is no power on the circuit.
