System fan sensors error message description

Error messages can be generated by the following chassis fan sensors.

Note: The "x" in the code represents the actual error condition.

Platform and sensor code	Sensor description
ENV00460x	Power distribution board fan (PwrDstBd#1).
ENV00461x	System fan 3.
ENV00462x	System fan 2.
ENV00463x	System fan 1.
ENV00464x	Processor fan 1 (proc Fan 1).

The following table lists the error messages that can be generated by the chassis and CPU fan sensors. The corrective action for this error message grouping is below the error message description.

Note: "[d]" in the sample error message represents one of the two fan sensors.

If "x" is...	Sample error message	Description
1	[d] does not read	Cannot read [d] sensor.
2	[d] is in critical high state	[d] speed read exceeds critical high threshold.
3	[d] is in warning high state	[d] speed read exceeds warning high threshold.
4	[d] is in warning low state	[d] speed read exceeds warning low threshold.
5	[d] is in critical low state	[d] speed read exceeds critical low threshold.
6	[d] expected high interrupt did not occur	Missing interrupt when the [d] speed exceeds warning high threshold.
7	[d] expected low interrupt did not occur	Missing interrupt when the [d] speed exceeds warning low threshold.

Corrective action

The following table lists the corrective action that can be taken for error messages generated by the fan sensors.

Error message	Corrective action
ENV004611-ENV004637	Replace the motherboard.
ENV004601-ENV004607 ENV004641-ENV004647	Check for fans spinning. If they are not, Replace the fans. If the problem remains, replace the motherboard.
