Recommended Troubleshooting Methodology - HP AB464-9003F Service Manual

Should a failure occur, the front panel LEDs, the diagnostic panel LEDs, and the system event
log (SEL) will help you identify the problem or FRU:
LEDs. The front panel LEDs and LAN LEDs of the server change color and blink to help
identify specific problems.
The System Event Log ( SEL) provides detailed information about the errors identified by
the LEDs.
For system alerts of levels 3-5, the attention condition on the system LED can be cleared by
accessing the logs using the slcommand, available in the MP Main Menu. To access the iLO 2
MP from the console serial port, enterCTRL-B or ESC-( .
If the LEDs and SEL do not give you enough information for you to identify the problem you are
experiencing, Hewlett Packard Enterprise also provides diagnostic tools with each operating
system. See
NOTE: Always check the iLO 2 MP system event logs (SEL) in the case of a blinking yellow
or red front panel LED, before replacing any hardware.

While we do suggest that you follow the recommended troubleshooting methodology, and use
the troubleshooting information in this guide, you may elect to go directly to the information which
corresponds to your own entry point of choice.
