Description
Note
This command only applies to the AT-8524POE switch.
This command displays the status of the fan control feature and the
cooling fans in the switch. The fan control feature automatically adjusts the
speed of four of the switch’s five cooling fans based on the ambient
temperature of the room or wiring closet where the unit is installed and the
load requirements of the PoE devices connected to the ports on the unit.
When the feature is disabled, all fans operate at their highest possible
speed. When enabled, fan speed is based on the temperature and the
PoE load requirements. To activate this feature, refer to “SET SYSTEM
FANCONTROL” on page 68.
Figure 8 illustrates the information displayed by this command.
