a fan failure).
Ensure that none of the following conditions exist:
•
A cooling fan has been removed or has failed.
•
System cover, air shroud, memory module blank, or
back filler bracket is removed.
•
Ambient temperature is too high.
•
External airflow is obstructed.
If the problem persists, see the Getting help section.
Electrical indicator The indicator turns solid amber if the
system experiences an electrical error
(for example, voltage out of range, or
a failed power supply unit (PSU) or
voltage regulator).
Check the System Event Log or system messages for the
specific issue. If it is due to a problem with the PSU,
check the LED on the PSU. Reseat the PSU. If the
problem persists, see the Getting help section.
Memory indicator
The indicator turns solid amber if a
memory error occurs.
Check the System Event Log or system messages for the
location of the failed memory. Reseat the memory
module. If the problem persists, see the Getting help
section.
PCIe indicator
The indicator turns solid amber if a
PCIe card experiences an error.
Restart the system. Update any required drivers for the
PCIe card. Reinstall the card. If the problem persists, see
the Getting help section.
NOTE:
For more information about the
