a. Power off the server using the power switch and unplug the AC power cords
and any cables.
b. Disconnect the power distribution cable between the drive cage and the
power distribution module and then reconnect it.
c. Verify that the SCSI interface is correctly installed from SCSI A channel
connector on the system board to the connector on the SCSI cage.
d. Ensure that the SCSI bus is loaded properly.
e. Reconnect the AC power cords and any cables. Restart the server to
determine whether the LEDs now become illuminated during the boot. If not,
contact your reseller.
4. If the LED indicator on a single disk drive is not illuminated during boot, the disk
drive might be installed incorrectly, or its lightpipes might be damaged.
Check the lightpipe on the disk drive as follows:
a. Remove the disk drive.
b. Inspect the lightpipes for damage. If a lightpipe is damaged, contact your
reseller.
CAUTION:
you inspect them or when you reinsert the disk drive.
c. Reinstall the disk drive.
d. Restart the server to determine whether the LED now becomes illuminated
during the boot. If not, contact your reseller.
5. Use the EFI shell command info io to check the SCSI drives.

Identifying and Diagnosing Hardware Issues

Should a failure occur, the server LEDs, the diagnostic LEDs, and the SEL help you
identify the problem.
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, Hewlett Packard Enterprise 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
flashing 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.

Systems with the Optional Management Processor Installed

Table 19 details the LED states that exist for servers having an optional iLO MP card
installed.
The lightpipes are fragile. Be careful not to damage them when
