I have a bit of a strange one here!
We have a location with a bunch of Aruba 2930M's with redundant power supplies, and a 5400zl with redundant supplies and a PoE card in it. There are a bunch of devices hanging off already (CCTV cameras, intercoms, UBNT AP's) and they all get powered up just fine. We have an elevator interface (Butterfly MX relay box) that looks like it wants to take power but won't, the poe light flashes on for about half a second ever few seconds. If we put a standard PoE injector inline it powers up just fine, and if I plug it into a Cisco SG300 with PoE it runs without any issues or special config.
I have tried forcing the class, forcing the wattage, and every other PoE setting I can find in the cli, even tried legacy mode, and nothing will let this device power up. The device is supposed to be 802.3af compliant
Config guide
The customer has some of these units installed in other buildings and I am trying to get one of my guys to track one down and see how it is hooked up and what type of switch it is hanging off.
Has anybody else seen issues with an Aruba switch not playing nice with PoE?
