Table 4. Status LED indicators and descriptions
Icon 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 congured in a RAID array, restart the system, and
enter the host adapter conguration 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.
• Ambient temperature is too high.
• External airow is obstructed.
If the problem persists, see Getting help.

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 specic 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
