Changing the Chassis Temperature Polling Interval
The software reads the temperature sensor and polls other hardware sensors according to the value set for the
chassis poll time, which is 60 seconds by default. You can change the chassis poll time using the CLI.
To change the chassis poll time, enter a command such as the following at the global CONFIG level of the CLI:
ServerIron(config)# chassis poll-time 200
Syntax: chassis poll-time <value>
The <value> can be 0 – 65535.
Managing Fan Settings and Temperature Sensors
The ServerIron 4G Series has two three-speed fans that operate at hi speed. Both fans operate simultaneously
at the same speed. If one fan fails, it does not affect the operation of the other fan.The fans can operate at speeds
of low, medium, and high.
Displaying Management Module CPU Usage
You can display the amount of the management module’s CPU in use. To do so, enter the following command at
any level of the CLI:
Syntax: show cpu
The CPU Usage (%) field shows the percentage of management module CPU used by each task.
The total CPU usage may not add up to 100 percent. The total may not include resources used by the
management processes.
A problem could exist If the CPU usage is distributed unevenly to one task, other than the idle task, for a prolonged
period. If this situation occurs, contact Foundry’s technical support for assistance.
