Hard drive 
indicator
The indicator flashes amber 
if there is a hard drive error.
Check the System Event Log to determine 
the hard drive that has an error. Run the 
appropriate Online Diagnostics test. Restart 
the system and run embedded diagnostics 
(ePSA). If the hard drives are configured in a 
RAID array, restart the system and enter the 
host adapter configuration utility program.
Electrical 
indicator
The indicator flashes 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.
Temperature 
indicator
The indicator flashes amber 
if the system experiences a 
thermal error (for example, a 
temperature out of range or 
fan failure).
Ensure that none of the following 
conditions exist:
• A cooling fan is removed or has failed.
• System cover, memory module blank, 
or back filler bracket is removed.
• Ambient temperature is too high.
• External airflow is obstructed.
