Use the information in Table 2-2 to troubleshoot power supply problems.

Cause Possible
Solution
Power supplies are not
connected properly.
Check for loose connections. Refer to
“Loose Connections” in this chapter for
more information.
Power supplies are not
working.
If the power supplies have LEDs, be sure
that they indicate that each power supply
is working properly. Refer to your
server-specific user documentation for
details on LEDs.
If LEDs indicate a problem with a power
supply, replace the power supply.
Power is not working
properly or power-related
errors are occurring.
Server does not boot.
System does not have
enough power.
Be sure that the system has enough
power, especially if you recently added
hardware. Additional power supplies may
need to be added. Check the system
information from the Integrated
Management Log (IML) and use your
server-specific user documentation for
product-specific information. Refer to
“Integrated Management Log” in
Chapter 4.
System Power Module
Some servers use one or more System Power Modules (SPMs) to distribute direct
current to system components. If your system uses SPMs, use Table 2-3 to
troubleshoot SPM problems.
