through the iLO 3 MP serial text interface, or through Secure Shell, or through the web GUI on the
iLO 3 MP LAN.
You can now determine which area of the system requires further analysis. For example, if the symptom
was "system will not power-up", the initial troubleshooting procedure might indicate a issue with the DC
power rail not coming up after the power switch was turned on.
You have now reached the point where the failed CRU has been identified and needs to be replaced.
Perform the specific removal and replacement procedure, and verification steps.
NOTE:
If multiple CRUs are identified as part of the solution, a fix cannot be guaranteed unless all identified
failed CRUs are replaced.
You might have to perform specific recovery procedures to finish the repair. For example, if the system
board is replaced, you need to restore customer specific information.
Should a failure occur, the System Insight Display LEDs, SEL and FPL help you identify the issue or
CRU:
• LEDs. The front panel LEDs and LAN LEDs of the server change color and blink to help identify
specific issues.
• The System Event Log (SEL) provides detailed information about the errors identified by the LEDs.
• The Forward Progress Log (FPL) provides details about the boot progress of the server.
The System Insight Display LEDs are cleared after the issue is corrected or the CRU is replaced and by
cycling AC power.
If the LEDs, SEL and FPL do not give you enough information to identify the issue, Hewlett Packard
Enterprise also provides diagnostic tools with each operating system (see Troubleshooting tools on
page 91 for more details).
NOTE:
Always check the iLO 3 MP SEL in the case of a blinking yellow or red front panel LED, before
replacing any hardware. The default display mode is Keyword mode. You can also view the error
messages in Text mode.

Recommended troubleshooting methodology

The recommended methodology for troubleshooting a server error or fault is as follows:
Procedure
1. Consult the system console for any messages, emails, etc., pertaining to a server error or fault.
2. View the front panel LEDs (power, SID, and system health), either locally, or remotely through the iLO
3 MP vfp command.
3. Compare the state of the server LEDs (off; flashing or steady; red, green, or amber) with the LED
states listed in the LED Panel State Table in this section.
4. Go to the step number of the Basic Low End Troubleshooting Table, as specified in the right column of
the LED Panel State Table, located in the row which corresponds to your front panel LED display
state.
