Table 3. Diagnostic indicators
Icon Description Condition Corrective action
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.
