ambient temperature is out of
range or there is a fan failure).
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 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.
Ensure that none of the following conditions exist:
● A cooling fan has been removed or has failed.
● System cover, air shroud, or back filler bracket is removed.
● Ambient temperature is too high.
● External airflow is obstructed.
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.
