TABLE 43 Temperature threshold information for modules and fan speeds (continued)
This field... Displays...
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.
