See below for meaning of message. I suggest thay you check with a cable tester that all wires in your cabling systems are correctly paired.

Error Message ILPOWER-5-IEEE_DISCONNECT: Interface [chars]: AC disconnect

Explanation This message means that the powered device is no longer connected to the switch or that the connected powered device is being powered by an external AC power source. No power is on the switch PoE port. [chars] is the interface.

Recommended Action No action is required.
