7-9-4-5 Main Power Supply Troubleshooting Flow Chart Procedures (cont'd)
7-9-4-5-3 New PS and Backplane Test Procedure
Order a new Power Supply and Backplane.
With the system powered-down and the rear panel Main Power Switch off, install the new Backplane.
Power-up the system, wait for simulator mode and measure the voltage at TC-3. If the voltage measured
is between 23V and 25V, the test passes. Return the new Power Supply to service.
If the voltage at TC-3 is not in the acceptable range, power-down the system. Turn the rear panel Main
Power Switch off and install the new Power Supply. Power-up the system, wait for simulator mode and
measure the voltage at TC-3. If the voltage measured is between 23V and 25V, the test passes. Return
the new Power Supply to service. If the voltage is not in the acceptable range, the test fails.
With the system powered-down and the rear panel Main Power Switch off, re-install the old Backplane.
Power-up the system, wait for simulator mode and measure the voltage at TC-3. If the voltage measured
is between 23V and 25V, the new Backplane can be returned to service. If not, re-install the new
Backplane.

Remaining Parts Procedure

With the system powered-down and the ON/OFF Button LED OFF, install the Fan Tray. Power-up the
system. If the fans don't run or the GFI power LED is OFF, replace the Fan Tray and repeat this step.
If the fans are running and the GFI power LED is ON, go to the next step.
With the system powered-down and the ON/OFF Button LED OFF, install the next card in the rack.
Power-up the system and check all power LED's on the cards. If any power LED's go out on any of the
installed cards and/or 24V at TC-3 is no longer present, replace the card you installed and go to the
beginning of this step. If all card LED's are ON, repeat this step for the next card to re-install, until all
cards are in place. If you find that all cards need to be replaced, stop. It is very unlikely that all cards
would be faulty. The problem is more likely the Power Supply. Replace the Power Supply and go to
"START" on the Troubleshooting Flow Chart.

Troubleshooting log files:

Applies to Main Power Supply Part Numbers 5205052, 5205052-2 and 5205052-3/-4 and
5205054-3.
When the system is able to boot up to some degree, the log files may give you more information about
voltage status.
The Main Power Supply has a log file that stores the last 10 Power Supply events in non-volatile
memory. During a normal system startup, the Power Supply may record 3 or 4 events in the log. The
log is circular, so the oldest entry will be over-written first. The Power Supply does not have a real time
clock. The Power Supply gets the date and time from the BEP. If an event is recorded in the log before
the Power Supply reads the date and time, the date and time fields will be filled with 0.
When the application software starts, the Power Supply Log is copied into logfile.txt. Possible log entries
are:
