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.Table 36 lists the associations between the
show chassis, show fan-threshold, and fan-threshold commands.
A "thermal block" refers to the group of high and low thresholds for all fan speed levels.
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.
