SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper determines whether local faults (as shown by the Local Fault indicator) will
be connected to the 7700FR frame's global status bus. Each of the cards of the module pair has a frame
status jumper. Be sure to change both jumpers to the same state.
FRAME STATUS:
To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's 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.
