Intelligent Diagnostics Module

This topic provides information about the Intelligent Diagnostics Module (hereinafter referred to as the IDM)
and the diagnostic LEDs on the module. Many errors are first indicated by a lit error LED on the diagnostic
panel of the server. If an LED is lit, one or more LEDs elsewhere in the server might also be lit to direct you to
the source of the error. See "System board LEDs" on page 40.
The following illustration shows the location of the IDM and the diagnostic LEDs on the IDM panel.
Depending on the model, your server might look slightly different from the illustration in this topic.

When the power supply error LED is lit in amber, it indicates that there is a power supply problem. To identify
the failing power supply, check the status LED near the power cord connector on the redundant power
supply. When the status LED is lit in green, it indicates that the power supply is working correctly. When the
status LED is lit in amber, it indicates that the power supply is likely to fail or has failed.
