System diagnostics and indicator codes
This section describes the diagnostic indicators on the system front panel that displays the system status during system startup.
Topics:
• Status LED indicators
• System health and system ID indicator codes
• iDRAC Quick Sync 2 indicator codes
• iDRAC Direct LED indicator codes
• LCD panel
• NIC indicator codes
• Power supply unit indicator codes
• Drive indicator codes
• Using system diagnostics
Status LED indicators
NOTE: The indicators display solid amber if any error occurs.
Figure 230. Status LED indicators
Table 85. 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 configured in a RAID array,
restart the system, and enter the host adapter
configuration 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.
● System cover, air shrouds, or back filler bracket
has been removed.
● Ambient temperature is too high.
● External airflow is obstructed.
If the problem persists, see the Getting help section.
