Viewing Information and Health Status of Fans

CMC, which controls fan speeds, automatically increases or decreases fan speeds based on system wide events. CMC generates an alert and increases the fan speeds when the following events occur:
  • CMC ambient temperature threshold is exceeded.
  • A fan fails.
  • A fan is removed from the chassis.
  • NOTE: During updates of CMC or iDRAC firmware on a server, some or all of the fan units in the chassis spin at 100%. This is normal.

To view the health status of the fans, in the CMC Web interface, do any of the following:

  1. Go to Chassis Overview > Properties > Health . The Chassis Health page is displayed. The lower section of chassis graphics provides the rear view of the chassis and contains the health status of the fan. Fan health status is indicated by the overlay of the fan subgraphic. Move the cursor over the fan subgraphic. The text hint provides additional information on the fan. Click the fan subgraphic to view the fan information on the right.
  2. Go to Chassis Overview > Fans > Properties . The Fans Status page provides the status and speed measurements in revolutions per minute, or RPMs, of the fans in the chassis. There can be one or more fans.
    • NOTE: In the event of a communication failure between CMC and the fan unit, CMC cannot obtain or display health status for the fan unit.
    For more information, see the CMC Online Help.
