Back End Processor (BEP) Troubleshooting

NOTE: When troubleshooting procedures refer to the GFI, this should be the MRX Board in a MRX
Configuration system. Troubleshooting procedures for a GFI Configuration MPS are essentially
the same for MRX.

System not booting up (or partially booting)
Collect error Logs and send them to the OLC to be evaluated. See:
"Collecting a Screen Capture with Logs" on page
to give as much detail as possible about the occurrence of the problem and the
date and time it showed up. On the scan screen, press
ALT + D.
• In the event of a Hard Drive failure, see:
(or partially booting)" on page
• Perform BEP Diagnostics. Run several loops of BEP diagnostics.
• If Cause / Symptom occurs frequent enough at the site, take the system to the
Minimum Configuration and see if the Cause / Symptom goes away.
Lock-ups and system errors may occur from high temperatures in the Card
Rack due to: a clogged air filter under the fan tray, clogged screens on the fan
tray assembly, clogged air intake to the BEP, bad fans in the BEP, and/or a
clogged, rear filter under the main power supply.
Inspect and clean all of the above.
If the filters were dirty or possibly clogged, reboot the system after cleaning the
screens/filters and monitor for reoccurrence of the problem. Also, check Card
Rack temperatures in the "logfile-TempMon.txt" file for abnormally high
operating temperatures. Readings between 65 and 80 degrees C can cause
lockups while readings of 80 degrees C or above will cause shut-downs. Also
check the BEP CPU temperature for operating temperatures greater than 45
degrees C.
If after cleaning the ai r filters, lock-ups and system errors contin ue to occur from
high temperatures in the Card Rack, components will need to be replaced.
If problems persist, reload Base Image and Application Software. See:
"Loading the Software" on page
