When syslog messages display a change in fan speed, you can identify which sensors triggered the change by checking show chassis
and show fan-threshold command output and looking for sensors with temperatures near threshold boundaries. The following table lists
the associations between the show chassis , show fan-threshold , and fan-threshold commands .
NOTE
A "thermal block" refers to the group of high and low thresholds for all fan speed levels.

The temperature threshold information for the various modules. The
module parameter indicates the following:
The current setting of the low and high temperature thresholds for the low,
medium, medium-high, and high fan speeds.

NOTE
As indicated in Table 44, the low fan speed for each module
does not have a default low temperature threshold value, nor
can you configure this value. The "-1" value that appears in the
Fan Speed Low field for each module is a Brocade internal
value only.
