8.1. SELECTING WHETHER LOCAL FAULTS ON THE BOARD
WILL BE MONITORED BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J4, on the bottom board, determines whether local faults (as shown by
the Local Fault indicator) on the bottom board will be connected to the 7700FR frame's global status
bus.
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.
