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 Configurations
page, in the Fan Configuration table, from the Value drop-down menu corresponding to Fan Offset,
select an option appropriately.
For more information about the Fan Offset feature, see the Online Help.
For setting up these features by using RACADM commands, user the following command:
racadm fanoffset [-s <off|low|medium|high>]
For more information about the fan offset-related RACADM commands, see the Chassis Management
Controller for PowerEdge VRTX RACADM Command Line Reference Guide available at dell.com/support/
Manuals.
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 Configurations
page, in the Blower Configurationtable, 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.
