Lenovo 2577, 2593 Diagnostic module, Intelligent Diagnostics Module IDM, Power supply error LED

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 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 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

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.
