Usage Guidelines

Fanless mode is supported only on ICX 7150-24P and ICX 7150-48P devices.

Fanless mode can be enabled only if the PoE power allocation is less than or equal to 150W. If the PoE power allocation is more than 150W, PoE load must be reduced by removing PoE interfaces manually or by unplugging PoE devices.

When fanless mode is enabled, the fan speed is set to zero RPM.

Fanless mode is enabled from the active console.

Even if fanless mode is configured on a switch, fans will be turned on temporarily during boot up or reboot and will be turned off after the boot up.

The no form of the command resets the fan speed to auto and reinstates the PoE budget to the default value.

Examples

The following example enables fanless mode on the device. 

device(config)# chassis fanless 1

The following example enables fanless mode on all supported units of stack. 

device(config)# chassis fanless all
