Troubleshoot Hardware Faults
The CMOD Fault Remind Test Circuit
The CMODs have an internal test circuit that you can use to locate failed DIMMs and verify
a failed CPU after removing the CMOD from the server. The DIMM and CPU Fault Remind
circuits hold an electrical charge for 10 minutes after power is removed from the server,
allowing enough time to remove the CMOD and use the circuit.

and Processor (FRU)” on page 161

Troubleshooting System Cooling Issues
Maintaining the proper internal operating temperature of the server is crucial to a the health of
the server. To prevent server shutdown and damage to components, address over temperature
and hardware related issues as soon as they occur. If your server has a temperature fault, the
cause of the problem might be:
■
“External Ambient Temperature Too High” on page 68
■
■
“Hardware Component Failure” on page 69
External Ambient Temperature Too High
If the ambient temperature in the server space is too high, the cool air that is pulled into the
server cannot cool the server sufficiently to prevent the internal temperature from rising. This
can cause poor performance or component failure.
Action
: Check the ambient temperature of the server space against the environmental
specifications for the server. If the temperature is not within the required operating range,
remedy the situation immediately.
Prevention
: Periodically check the ambient temperature of the server space to ensure that it
is within the required range, especially if you have made any changes to the server space (for
example, added additional servers). The temperature must be consistent and stable.
Airflow Blockage
The server cooling system uses fans to pull cool air in from the server front intake vents and
exhaust warm air out the server back panel vents. If the front or back vents are blocked, the
