Task / Conclusion
Measure test connector, pin 12 and ground
5Vstb.
Test connector pin (24V) to see if system turns
ON.
- Use the Power ON/Off button on the
Motherboard.

1. BEP PS
2. EPS
3. BEP

to OP Panel.
- Main Power Supply Fan failure may cause
this problem. Use a mirror to look at the fans;
check if they try to rotate at boot up (two
people may be needed to test this).

If the fans do not move, tip the Main PS and
gently move each fan with a screw driver to
move them from their current position.
Sometimes removing the PS is enough
movement to move the fans.
If the Main PS powers up after the fans are
moved, you will see a failure message in the
Log Files. See:
7-9-4-6 "Main Power Supply
Logs" on page 7-214.
If the fans do not mo ve after this step, the Main
PS needs replacement.
NOTE: This is a rare occurrence. Monitor site
for future occurrences.
