ROPRIETARY
If the system is booting, check error logs and
run diagnostics.
· If 24V is present, then the simulator mode
may be caused by problems with GFI board or
cable. Check if the Fan Tray, under the Card
Rack, is running (Fan Tray uses 24V to run).
Fan Tray running means 24V is present.
If not running, try isolating the problem by
removing all cards in the Card Rack, except
the GFI.
Observe the LEDs in the Card Rack.
If no lights are observed, disconnect GFI and
connect another board. Observe LEDs.
If the Fan Tray is not running, go to isolate the
Backplane.
· If 24V is not present, see:
Power Supply Troubleshooting Flow Chart" on
page 7-211.
