Like the ENH200/ENH202/ENH500, the ENS202EXT has two Ethernet ports: LAN (PoE) and LAN. The proprietary PoE injector for the ENS202EXT must be connected to the LAN (PoE) port to power the AP.
In this case, the user did not connect the PoE injector to the ENS202EXT LAN (PoE) port. The ENS series LAN (PoE) port placement is different from the ENH series. Facing the back panel of the ENH200/ENH202/ENH500, the LAN (PoE) is on the left while facing the back panel of an ENS series AP/Bridge the LAN (PoE) is on the right.
