Description
Condition
Corrective action
Drive indicator
The indicator turns solid amber if
there is a drive error.
•
Check the System Event
Log to determine if the drive
has an error.
•
Run the appropriate Online
Diagnostics test. Restart the
system and run embedded
diagnostics (ePSA).
•
If the drives are configured
in a RAID array, restart the
system, and enter the host
adapter configuration utility
program.
Temperature indicator
The indicator turns solid amber if
the system experiences a
thermal error (for example, the
ambient temperature is out of
range or there is 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
Getting help
.
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
Getting help
.
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
Getting help
.
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
Getting help
.
