Note any LEDs that are lit, and then close the drawer.
Look at the system service label on the top of the server, which gives an overview of internal components
that correspond to the LEDs on the EasyLED panel. This information and the information in “EasyLED”
on page 20 can often provide enough information to diagnose the error.
3. Remove the server cover and look inside the server for lit LEDs. Certain components inside the server
have LEDs that will be lit to indicate the location of a problem.
Remind button
You can use the remind button on the EasyLED panel to put the system-error LED on the operator
information panel into Remind mode. When you press the remind button, you acknowledge the error but
indicate that you will not take immediate action. The system-error LED flashes while it is in Remind mode
and stays in Remind mode until one of the following conditions occurs:
• All known errors are corrected.
• The server is restarted.
• A new error occurs, causing the system-error LED to be lit again.
EasyLED switch
The EasyLED switch allows you to review error indications after the server has been powered down.
Press and hold the EasyLED switch, located on the system board, to see the LEDs that were lit before
you removed power from the server. The LEDs will remain lit for as long as you press the switch, to a
maximum of 25 seconds.
EasyLED LEDs
The following table describes the LEDs on the EasyLED panel and suggested actions to correct the detected
problems.
Note: Check the system-error log or IMM system event log for additional information before replacing a FRU.
