Resetting LEDs on power distribution unit
A red LED next to any of the 32 power output connectors indicates a short circuit in the building wiring
or the terminal equipment. To reset the LED:
1 Disconnect the terminal equipment from the wall jack.
2 If the LED goes off, the terminal equipment is faulty and must be replaced. If the LED is still lit,
find and repair the short circuit in the building wiring.
3 Reconnect the terminal equipment to the wall jack and retest terminal equipment operation.
