In the Fans & Temperature section, select one of the following radio buttons.
•
Off . The fans are off and produce no noise. You can only manually set the fans
in Off mode.
•
Quiet. The fans function from 25 to 75 percent speed and can reach 100 percent
speed. Quiet mode is the default mode. At 25 percent speed, the fans produce
minimal noise. Fan noise increases at 50 percent speed and even more so at
75 percent speed. At 100 percent speed, the fans produce considerable noise.
•
Cool. The fans consistently function at 100 percent speed and produce
considerable noise. In Quiet mode, the switch might automatically change back
and forth between Cool mode and Quiet mode until a temperature, PoE budget,
or traffic load condition returns within thresholds.
The fan setting changes immediately. However, depending on the switch model, if
the temperature detected by the temperature sensor exceeds its threshold, a PoE
budget is exceeded, or a traffic load condition is exceeded, the switch automatically
overrides your manual setting.
