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 41.
The following illustration shows the location of the IDM and the diagnostic LEDs on the IDM panel in the
front of the server. Depending on the model, your server might look slightly different from the illustrations in
this topic.
