Diagnostic module
This topic provides information about the diagnostic module and the diagnostic LEDs on the panel of the
module. To locate the diagnostic panel, see “Front view of the server” on page 16.
Your server comes with one of the following diagnostic modules:
• Intelligent Diagnostics Module (IDM)
• Intelligent Diagnostics Module Premium (IDM Premium)
Many errors are rst 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 49.
Intelligent Diagnostics Module (IDM)
The IDM is available in some models to provide basic diagnostic functions. The following illustration shows
the diagnostic LEDs on the IDM panel.

1 Power supply error LED 4 Memory module status LED
2 Ambient temperature limit LED 5 Microprocessor status LED
3 System fan error LED
1 Power supply error LED
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 LED is lit in green, it indicates that the hot-swap redundant power supply is working
correctly. When the LED is lit in amber, it indicates that the hot-swap redundant power supply is likely to
fail or has failed.
2 Ambient temperature limit LED
When this LED is lit in amber, it indicates that the ambient temperature is below 7°C (44.6°F) or over 40°C
(104°F), which is not proper for server operation.
3 System fan error LED
When the system fan error LED is lit in amber, it indicates that the system fan(s) are operating slowly or have
failed. To identify the failing system fan(s), check the status LEDs on the system board. See “System
board LEDs” on page 49
