Cause

PoE device will not power up

Resolution

There are two ethernet ports on most PoE injectors, however only one port provides power to the PoE device.

  1. To correctly power up the PoE device, plug an ethernet cable into the OUT port of the PoE injector.
  2. Plug the opposite end of the cable into the PoE device's ethernet connection port or NIC.
