If not, contact your reseller.
Step 5. Use the EFI shell command info io to check the SCSI drives.
Identifying and Diagnosing Hardware Problems
Should a failure occur, the server LEDs, the diagnostic LEDs, and the SEL help you identify the problem:
• LEDs. The server LED, LAN LED, and diagnostic LEDs on the display panel of the server change color
and blink in different patterns to help identify specific problems. LEDs on the front and rear panels of the
server display LAN activity.
• The SEL provides detailed information about the errors identified by the LEDs.
If the LEDs and SEL do not give you enough information for you to identify the problem you are experiencing,
HP also provides diagnostic tools with each operating system.

Power and System LEDs

The power and server LEDs indicate the state of the server. When the server LED is blinking yellow or red, a
problem exists.
NOTE When the optional iLO MP card is installed, the four diagnostic LEDs on the display panel are
disabled.

Table 5-2 details the LED states that exist for servers having an optional iLO MP card installed.
