The output displays the following information.
TABLE 43 Temperature threshold information for modules and fan speeds
This field... Displays...
Thermal Sensor Control Block
(THERMAL_SENSOR_TEST_RULE_module) The temperature threshold information for the various modules. The
module parameter indicates the following:
• MP - The active management module
• STANDBY_MP - The standby management module
• SNM - The switch fabric module
• LP - An interface module
Fan Speed Low or Med or Med-Hi or Hi 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.
State = 0 (FAN_STATE_LOW) For Brocade internal use only.
max_ts_shut_off_count For Brocade internal use only.
shut_off_count = 0 0 0 0 0 0 0 0 For Brocade internal use only.
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.

block)
