We are about to deploy the Aruba IAP-105s firm wide to the tune of about 200 APs. I have been having issues with my pilot group where the IAP-105 suddenly fail. Fail in the sense that they no longer are able to pull Power from the switch. The switch reports
ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/15: Power Controller reports power Imax error detected
which basically means the switch sees the device trying to pull more power than it can support. Now I have 10 other APs connected the same type of switch running the same IOS. The failures have no pattern. Today I had a 4th one fail in this manner. Once they fail they will work only if they are powered externally.
I had a second one fail today as well. This was the one that I used to replace the failed one. I did plug it back into the same port and it failed about an hour later. I have had APs fail on other ports so it isn't isolated to a single port or switch. However, the second one to fail today will work if it is connected to a Cisco 3750-x which supports up to 30mw of power per port.
I have changed switches, cables, IOS on the switch and the IAP.
Anyone having similar issues or know of anyone that is.
