Using the Medium Fan Offset setting for example, increases the speed of fans 1–6 by 50% of its maximum speed. The

increase is above the speed already set by the system for cooling on the basis of installed hardware configuration.

With any of the Fan Offset options enabled, the power consumption will be increased. The system will be louder with the

Low offset, noticeably louder with the Medium offset, and significantly louder with the High offset. When the Fan Offset

option is not enabled, the fan speeds will be reduced to the default speeds required for system cooling for the installed

hardware configuration.

To set the offset feature, go to Chassis Overview → Fans → Setup. On the Advanced Fan Configuration page, from the

Value drop-down menu corresponding to Fan Offset, select appropriately.

For setting up these features by using RACADM commands, user the following command:

racadm fanoffset [-s <off|low|medium|high>]

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 off. When ECM is enabled, the blowers have the capability to deliver approximately 20% more airflow

per blade.

To set the ECM mode, go to Chassis Overview → Fans → Setup. On the Advanced Fan Configuration page, from the

Value drop-down menu corresponding to Enhanced Cooling Mode, select appropriately.
