Identifying and Diagnosing Hardware Problems
Should a hardware failure occur, the system LED and the SEL helps you identify the problem:
•
LEDs. The lights on the front bezel of the server change color and flash in different patterns
to help identify specific hardware problems. LEDs on the rear panel of the server display
LAN status.
•
SEL. The SEL provides detailed information about the errors identified by the LEDs. Use
the iLO MP to view the SEL.
Troubleshooting Using LEDs
If you suspect a hardware failure, the power and system LEDs, located on the front control panel,
will help you identify the problem. The following sections describe their functions. Additional
LEDs are provided on the system board (See
“System Board LEDs” (page 119)
). You may want
to back up your data or replace a component before it fails.
The boot process is monitored by the iLO MP. With the current iLO MP functionality, the four
diagnostic LEDs are disabled (always off). You can monitor server operation from a console
using the iLO MP.
Figure 5-1
shows the control panel LEDs.
