The display shows the following information:
Changing the temperature polling interval
By default, the BigIron RX Series system reads the temperature sensor on each module every 60
seconds. To change the interval at which the system reads the temperature sensors on each
module, enter a command such as the following at the global CONFIG level of the CLI:
BigIron RX(config)# temp-poll-period 120
Syntax: temp-poll-period <seconds>
For the <seconds> parameter, you can specify a value from 30 – 120. You can also specify 0,
which disables the system from polling the temperature sensor on each module.
Manually setting the fan speed
Typically, the management module, in conjunction with default settings of low and high
temperature thresholds, determines the speed of the two four-speed fans. (For information about
changing the low and high temperature thresholds, refer to
“Changing temperature thresholds for
modules and fan speeds” on page 117.) If desired, you can manually set the speed of the fans. The
set-fan-speed command in the Privileged EXEC level of the CLI allows you to manually set the speed
of the fans.
For example, to set the speed of fan 0 to medium-high, enter the following command:
BigIron RX(config)# set-fan-speed med-hi
Syntax: set-fan-speed <fan-speed>
For the <fan-speed> parameter, you can specify the following:
auto – The system is adjusted by the monitoring system.
hi – The system sets the fan speed to high.
TABLE 21 Temperature threshold information for modules and fan speeds
This field... Displays...
Thermal Sensor Control Block
(THERMAL_SENSOR_TEST_RULE_<mod
ule>) 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 20 on page 118, 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
shut_off_count = 0 0 0 0 0 0 0 0 For Brocade internal use only.
