For information on LED locations and states, see Front panel LEDs on page 94.
• The SEL provides detailed information about the errors identified by the LEDs.
For server alerts of levels 3-5, the attention condition on the server LED can only be cleared by cycling
DC power.
If the LEDs and SEL do not give you enough information for you to identify the issue you are
experiencing, Hewlett Packard Enterprise also provides diagnostic tools with each operating system (see
Troubleshooting tools on page 92 for more details).
NOTE:
Always examine the iLO 3 MP SEL in the case of a blinking yellow or red front panel health LED,
before replacing any hardware.
Executing recommended troubleshooting methodology
The recommended methodology for troubleshooting a server blade error or fault is as follows:
Procedure
1. Consult the system console for any messages, emails, and so on, pertaining to a server blade error or
fault.
2. View the front panel LEDs (power and health), locally or remotely through the iLO 3 MP vfp
command.
3. Read the symptom/condition information in the left column of
Table 10.
4. Perform the actions specified in the Action column.
For more details, see the appropriate subsection of this chapter, where this information is provided in the
Action column. The Action you are directed to perform might be to access and read one or more error
logs (the event log and/or the FPL).
You can follow the recommended troubleshooting methodology, and use Table 10 and Table 11 or go
directly to the subsection of this chapter which corresponds to your own entry point. Table 9 provides the
corresponding subsection or location title for these different entry points (for example, to start by
examining the logs, go directly to Errors and error logs on page 103).
