Troubleshooting Hardware Faults Using Oracle ILOM
Once AC power is connected to the system (providing standby power), the System Fault
Remind circuit energy storage capacitor takes about 10 minutes to charge to 63% (which should
be sufficient to turn on the indicator) and about 20 minutes to be fully charged. When you push
down on the Fault Remind button, its power indicator should show green when the circuit has
enough power to identify faulted components.
For information about how to use the circuits to identify failed components, see
Failed Memory Riser Card, DIMM, or CPU” on page 86
.
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-related fault,
the cause of the problem might be one of following:
■
“External Ambient Temperature Too High” on page 52
■
■
“Internal Pressures Compromised” on page 53
■
“Hardware Component Failure” on page 53
External Ambient Temperature Too High
Server component cooling relies on the movement of cool ambient air pulled into the server
from its external environment. If the ambient temperature of the server's external environment
is too high, cooling does not occur, and the internal temperature of server and its components
increases. This can cause poor server performance or a failure of one or more components.
Action
: Check the ambient temperature of the server space against the environmental
specifications for the server (see the
Installation Guide
). 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.
