We have a number of 1524's at a customer site and one of them is not powered up and the power injector has the AP Power light on and the Fault light on solid. A picture is attached. Has anyone seen this? We have swapped out injectors and the injector is plugged into a UPS that is powering other Cisco gear without an issue.
What other type of equipment are you powering on this power injector now? I think these injectors don't use standard PoE (slightly higher voltage). Have you tried using the bad injector on another 1524? Also, are you running any PoE device off of the 1524 PoE port?
