Managing the cooling system 5 The display shows the following information: TABLE 21 Temperature threshold information for modules and fan speeds This field... Displays... Thermal Sensor Control Block (THERMAL_SENSOR_TEST_RULE_) Fan Speed Low or Med or Med-Hi or Hi State = 0 (FAN_STATE_LOW) max_ts_shut_off_count shut_off_count = 0 0 0 0 0 0 0 0 The temperature threshold information for the various modules. The parameter indicates the following: • MP - The active management module • STANDBY_MP - The standby management module • SNM - The switch fabric module • LP - An interface module 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. For Brocade internal use only. For Brocade internal use only. 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 For the 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 For the parameter, you can specify the following: auto - The system is adjusted by the monitoring system. hi - The system sets the fan speed to high.
