Usage Guidelines

Only the USG6510E/6510E-POE/6530E does not support this command.

This command is used in routine maintenance of the device. When you view that the temperature of the device is abnormal, you can use the command to judge whether the fan normally registers or whether the speed mode needs to be changed.
