Configuring Enhanced Cooling Mode for Fans
The Enhanced Cooling Mode (ECM) feature provides additional cooling support using the third
generation M1000e fans. The Enhanced Cooling Mode (ECM) for fans is available only when all nine fan
slots are populated with the new third generation M1000e fans. The new third generation M1000e fans
provide:
• Superior cooling to the installed blades compared to previous M1000e fan generations, when the
ECM feature is enabled.
• Cooling equivalent to previous generations of M1000e fans at the same power, when the ECM feature
is disabled.
ECM mode is recommended for:
• Blade server configurations with high Thermal Design Power (TDP) processors.
• Workloads where performance is a critical.
• Systems deployed in environments where the inlet temperature exceeds 30°C [86°F].
,
NOTE: In the Enhanced Cooling Mode (ECM), the new generation fans provide superior cooling
features when compared to current generation fans of M1000e chassis. This increased cooling is
not always needed and comes at the expense of higher acoustics (where the system can sound up
to 40% louder) and increased system fan power. You can enable or disable the ECM feature on the
basis of cooling required for a chassis.
By default, the ECM feature is disabled on a chassis. The ECM enabling and disabling operations are
recorded in the CMC logs. The ECM mode state is maintained after CMC failovers and chassis AC power
cycles.
You can enable or disable the ECM feature using the CMC Web interface or the RACADM CLI interface.
Configuring Enhanced Cooling Mode for Fans Using Web Interface
To configure Enhanced Cooling Mode (ECM) for fans using CMC 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.
