Low-Power Mode EM Policy Profile for Noise Reduction

The Low-Power Mode Environment Management (EM) Policy Profile feature reduces the operational noise levels of MX10004 and MX10008 chassis when you use 100G ports for the LC9600 line card. By enabling this mode, you can lower the default minimum fan speed from 60% to 44%, addressing the need for quieter environments. We recommend to enable this feature only when you use 100G optics. This feature is particularly beneficial in acoustically sensitive premises such as data centers, where maintaining low noise levels is essential without compromising cooling efficiency.

To enable low-profile mode EM policy profile, use the following CLI command:

set chassis fpc-empolicy-profile low-power-mode

After enabling this configuration, you can use the show chassis temperature-thresholds or show chassis fan command to view the updated fan speed details.
