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.
