Fan sensor error message description

Error messages can be generated by the fan sensors for existence and status. The corrective action for all fan sensor error messages is below all the error message descriptions.

Fan sensors for existence

Error messages can be generated by the hotswap fan sensors to indicate the existence of the fan module within the chassis.

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

Platform and sensor code	Sensor description
ENV00641x	Hotswap Fan 1.
ENV00642x	Hotswap Fan 2.
ENV00643x	Hotswap Fan 3.

The following table lists the error messages that can be generated by the fan module sensors.

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

If "x" is...	Sample error message	Description
1	[d] does not read	[d] module is not responding.
2	[d] is in bad state	[d] module is missing.

Fan sensors for status

Status error messages can be generated by the following baseboard fans within each fan module and the power supply fans within each power supply module.

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

Platform and sensor code	Sensor description
ENV00644x	Baseboard Fan 1.
ENV00645x	Baseboard Fan 2.
ENV00646x	Baseboard Fan 3.
ENV00647x	Baseboard Fan 4.
ENV00648x	Baseboard Fan 5.
ENV00649x	Baseboard Fan 6.
ENV00670x	PS Fan 1 (Power supply fan 1).
ENV00671x	PS Fan 2 (Power supply fan 2).
ENV00672x	PS Fan 3 (Power supply fan 3).
ENV00673x	PS Fan 4 (Power supply fan 4).

The following table lists the error messages that can be generated by the baseboard and power supply fan sensors.

Note: "[d]" in the sample error message represents one of the six baseboard fan sensors or one of the four power supply 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.
8	[d] can�t be speeded up	[d] cannot be speeded up by the system.
9	[d] can�t be slowed down	[d] cannot be slowed down by the system.
