The following illustration shows the LEDs on the indicator panel, located inside the
server.
Component LEDs
In addition to the indicator panel or display, individual LEDs are located on or near the
failing components. The LEDs are either on the component itself or on the carrier of the
component (memory card, fan, memory module, CPU).
The LEDs are amber, except for the power supplies. For the power supplies, two green
LEDs (ac power good and dc power good) indicate the fault condition for the power
supply.

1. Replace the failing component with the new component.
2. Log in as root user.
3. At the command line, type diag.
4. Select Task Selection.
