I've got a C2960PD-8TT-L that is supposed to be able to take PoE over it's 10/100/1000 port (which also bears the label 'PoE Input'). I'm trying to power it from a C3524-PWR-XL and it is not working. I've tried about everything at this point. It works fine with a 48v brick plugged into the AC input on the back but I can't get it to come up with PoE. I've tried the 3524 switch (which powers an Aironet and a 7960 phone just fine) and an external PoE injector with no success. If it's powered from the wall, the 3524 is showing it as ILP-Device unknown.
Is there some trick I'm missing here?
Thanks in advance for any help.
