Is there any way to detect receiving power from another PoE source in Aruba Mobility Access Switch?
Yes, starting from ArubaOS 220.127.116.11, a new alarm, Inline Power Detected On <slot/port/module> is introduced in the Mobility Access Switch to indicate that an interface is receiving power from another PoE source. This major alarm is indicated by the Status LED in the front panel with a blinking amber. You can view the active alarms using the show alarms command.
The following sample indicates that the interfaces GE0/0/1 and GE0/0/13 are receiving power from another PoE source:
