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. PSU Mem CPU ID PSU Mem CPU Figure 9.
