48 port 3560 PoE problems

Hi

Am trying to power a class 3 device off a 48 port 3560 PoE version
(obviously!) It's a door entry system and is compliant with 802.3af.

According to Cisco literature, the switch has intelligent power management
which will automatically deliver the required power to each port as
required. This is within the total power budget of 370W so you could not
power more than 24 class 3 devices at 15W per device.

However, I cannot get this class 3 device to work on the 48 port switch
although it will work on the 24 port version and it does work on HP switches
as well.

Has anyone come across this problem and do you know of any solutions?

Thanks.

Yes, it is a PS model. It powers Cisco IP Phones no problem..

Yes, that is what I was saying above - as long as you are within the power
budget, you should be able to plug any device into any port.

Actually, I want to do the opposite - to configure the port to allow a high
powered device to connect to it, not to prevent this from happening.
