output. See the Getting help section in this
document.
HDD indicator The indicator blinks amber if a hard
drive experiences an error.
See the System Event Log to determine the HDD
that has an error. Run the appropriate Online
Diagnostics test. Restart system and run embedded
diagnostics (ePSA). If the HDDs are configured in a
RAID array, restart the system and start the host

Electrical
indicator
The indicator blinks amber if the
system experiences an electrical
error (for example, voltage out of
range, or a failed PSU or voltage
regulator).
See the System Event Log or system messages for
the specific issue. If it is because of an issue with the
PSU, check the LED on the PSU. Reseat the PSU by
removing and reinstalling it. If the issue persists, see
the Getting help section in this document.
Temperature
indicator
The indicator blinks 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, cooling shroud, EMI filler panel,
memory-module blank, or back-filler bracket is
removed.
● Ambient temperature is too high.
● External airflow is obstructed.
See the Getting help section in this document.

memory error occurs.
See the system event log or system messages for the
location of the failed memory. Reinstall the memory
device. If the issue persists, see the Getting help
section in this document.

card experiences an error.
Restart the system. Update any required drivers for
the PCIe card. Reinstall the card. If the issue persists,
