Intelligent Diagnostics Module
This topic provides information about the Intelligent Diagnostics Module (hereinafter referred to as 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 46.
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 or system fan error LED is off, it indicates that the power supply or
system fan is working correctly. When the ambient temperature limit LED, memory module status LED,
or microprocessor status LED is off, it indicates that the server, memory module, or microprocessor
is operating at a normal temperature.
• When one error LED is lit in amber, it indicates potential errors. Check the information in the following
table for potential errors and corresponding solutions.
