Remote power troubleshooting
The LED marked IN will illuminate when the PoE injector is receiving power from the PSU. The LED
marked OUT lights up green when an Ethernet connection is recognized by the Digi EX15.
If the IN LED is not illuminated check the following:
n Ensure that the PSU is plugged into an AC power outlet and is receiving power.
n Ensure that the PSU power plug is correctly connected to the POE injector cable power input
socket.
If the OUT LED is not illuminated after connecting to the Digi EX15, verify the integrity of the Ethernet
cable.
Note The PoE injector must be connected to LAN port 1 on the Digi EX15 for the device to properly
receive power.
