Enhanced Cooling Mode (ECM) — Is a feature in the CMC that allows increased cooling capacity for the servers installed within the
PowerEdge VRTX chassis. Example uses for ECM are operation in a high ambient environment or using servers with high power (≥120W)
CPUs installed. The increased cooling capacity is achieved by allowing the four chassis blower modules to run at a higher speed. As a result,
the system power consumption and noise level may be increased when ECM is enabled.
When enabled, ECM will only increase the cooling capacity to the server slots within the chassis. It is also important to note that ECM is
not designed to provide increased cooling to the servers at all times. Even with ECM enabled, the higher blower speeds will only be seen
when the increased cooling is needed. Examples of this situation include high levels of server utilization or stress, and high ambient
temperatures.
By default, ECM is o. When ECM is enabled, the blowers have the capability to deliver approximately 20% more airow per blade.
To set the ECM mode, go to Chassis Overview > Fans > Setup. On the Advanced Fan Congurations page, in the Blower
Congurationtable, from the Value drop-down menu corresponding to Enhanced Cooling Mode, select an option appropriately.
For more information about the ECM feature, see the Online Help.
