Power supply fuse

The fuse protects the DC input from reverse voltage on the -48 VDC input. If you apply reverse
voltage to the G650 Media Gateway and the 655A power supply, the 655A fuse blows open to
protect the 655A power supply from damage. The fuse is located on each end of the rear
surface of the 655A power supply
supply on page 26). The DC input protection fuse and a spare fuse are located in the two fuse
positions.
If the G650 Media Gateway does not operate on DC input only, inspect the fuse. Remove the
655A power supply from the G650 Media Gateway and inspect the protection fuse.
Avaya ships a spare fuse with the power supply.
