Did the System LED on the Front Panel Turn On?
Answer Possible Reasons
Yes, If the system LED is green, and the power
green supply LED is amber:
A power supply problem may exist. The


power supply may not be connected or
inserted properly, may have a damaged
connector, or it may have failed.
The power supply backplane may need to


be replaced.
Nonvolatile RAM (NVRAM) may be


corrupted.
The system ROM may be corrupted.


If both the system LED and the power supply
LED are green, then a processor board, system
board or I/O board is failed.
IMPORTANT: Slots one and two in memory bank one must be populated when performing ROMPaq
disaster recovery.

The Next Step
If system LED is on then you may
assume that the following is true:
AC power is connected to the power


supply and providing adequate
power.
The power supply 14 pin signal


header cable is connected properly.
The cable connection between the


system and backplane is good.
The connection between the system


board and power switch is good.
1. Verify installation of the power
supplies and check all connections.
2. You may try clearing NVRAM. If it is
necessary to clear NVRAM, see
Appendix D for the correct switch
setting and procedure.
3. You may try performing ROMPaq
disaster recovery to replace a
corrupted system ROM image. If it
is necessary to perform ROMPaq
disaster recovery, see Appendix D
for the correct switch settings.
Refer to the Compaq Servers
Troubleshooting Guide for
procedures on ROMPaq disaster
recovery.
