SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J3 determines whether local faults (as shown by the Local Fault indicator)

FRAME STATUS:
To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LEDs and on the Frame's Fault Tally output) install this
jumper in the ON position (default).
When this jumper is installed in the OFF position local faults on this module will not
be monitored.
