Status LED indicators
The status LED indicators on the system front panel display error status during system startup.
NOTE:
No status LED indicators are illuminated when the system is turned off. To start the system, plug it into a
working power source and press the power button.
NOTE:
Status LED indicators are always off and only turn solid amber if any error occurs.

Description
Condition
Corrective action
Hard drive
indicator
The indicator turns solid amber if
there is a hard drive error.
Check the System Event Log to determine if the hard
drive 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.
Temperature
indicator
The indicator turns solid amber if the
system experiences a thermal error
(for example, the ambient
temperature is out of range or fan
failure).
Ensure that none of the following conditions exist:
•
A cooling fan has been removed or has failed.
•
System cover, air shroud, EMI filler panel, 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.
