Fan Status/Speed
The Environmental Module adjusts the speed of the four system cooling fans
based on the external ambient temperature. Fan speed increases to ensure
adequate system cooling as ambient temperature rises; conversely, it decreases as
ambient temperature falls. If the ambient temperature sensor Ñ or the
Environmental Module itself Ñ fails, a switch increases the fan system to full
speed.
The Fan Status/Speed Þeld displays the current operating speed of each fan as a
percentage of maximum operating speed. The current operating speed and status
is color-coded as shown in the table below.
It also allows you to administratively set the fans to full operating speed or auto
speed (controlled by ambient temperature level sensor). To do so:
1. Click on the appropriate fan speed selection: Auto or Full.
Power Subsystem

for the MMAC-Plus chassis, as well as the power subsystem status:
