Fanless Mode Support on the ICX 7150

Fanless mode enables the device to operate with the fans disabled while providing a PoE budget of 150 watts. That is, when fanless mode is enabled, the fan speed is set to zero RPM, thus allowing the device to operate silently.
Note: 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.

Fanless mode does not depend on the variations in the PoE power allocation and is not triggered based on the thermal policy. Fanless mode must be enabled manually using the chassis fanless command. If fanless mode is disabled, the fan speed is reset to auto and the PoE budget is reinstated to the default value. In a stacking configuration, fanless mode can be enabled only from an active console, and cannot be enabled from any member units, including standby units.

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