Health indicator The indicator turns solid blue if the
system is in good health.
None required.
The indicator flashes amber:
● When the system is turned on.
● When the system is in standby.
● If any error condition exists. For
example, a failed fan, PSU, or a
hard drive.
Check the System Event Log or system messages
for the specific issue. For more information
about error messages, see the Dell Event and
Error Messages Reference Guide at Dell.com/
openmanagemanuals > OpenManage software.
The POST process is interrupted without any video
output due to invalid memory configurations. See the
Getting help section.
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 the Getting help
section.
Temperature
indicator
The indicator flashes 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, 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.
Memory indicator The indicator flashes 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.
