Dell Chassis Management Controller Version 6.0 for PowerEdge M1000e User’s Guide

Configuring Enhanced Cooling Mode for Fans Using Web Interface

1. In the system tree, go to Chassis Overview, and then click Fans > Setup.
   The Advanced Fan Configurations page is displayed.

   NOTE If ECM is disabled and all the fans in the chassis do not support ECM, then the Setup tab to access the Advanced Fan Configurations page is not displayed.
2. In the Fans Configuration section, from the Enhanced Cooling Mode drop-down menu select Enable or Disable.
   For more information about the field descriptions, see the CMC Online Help.

   NOTE

   The Enhanced Cooling Mode option is available for selection only if:

   • All the fans in the chassis support ECM feature. In this case, you can enable or disable the ECM mode.
   • ECM is already enabled and the fan configuration is changed to Mixed Mode or all fans do not support ECM mode. In this case, the ECM mode can be disabled, but cannot be enabled again until all fans in the chassis support ECM.

   NOTE The Enhanced Cooling Mode and the Apply options are grayed out if:

   • ECM mode is already disabled and fan configuration consists of unsupported fans along with supported fans. The information section displays a message listing the fans that are incompatible with ECM feature.
   • ECM mode is already disabled and Max Power Conservation Mode (MPCM) is enabled. The information section displays a message that ECM is not supported when MPCM is enabled.

   For more information see the CMC Online Help.

   If the ECM feature is disabled, you cannot enable the feature again until all fans in the chassis support ECM.

3. Click Apply.
   An operation successful message is displayed after the ECM option is successfully enabled or disabled. The ECM mode does not get enabled if:

   • The extra power required for supported fans is not available.
   • Any of the fans in the chassis does not support ECM.
   • MPCM is already enabled.

   An alert message with the reason for ECM not getting enabled is displayed .

   NOTE If you try to enable MPCM when ECM is enabled, the ECM mode changes to enabled but unsupported state.
