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
ENV00761x	Hotswap Fan 1.
ENV00762x	Hotswap Fan 2.
ENV00763x	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
ENV00764x	Baseboard Fan 1.
ENV00765x	Baseboard Fan 2.
ENV00766x	Baseboard Fan 3.
ENV00767x	Baseboard Fan 4.
ENV00768x	Baseboard Fan 5.
ENV00769x	Baseboard Fan 6.
ENV00790x	PS Fan 1 (Power supply fan 1).
ENV00791x	PS Fan 2 (Power supply fan 2).
ENV00792x	PS Fan 3 (Power supply fan 3).
ENV00793x	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.
