Usage Guidelines

Usage Scenario

During routine maintenance or when a fault occurs on a device, you can run the display voltage command to check whether the voltage of the device is within a normal range and locate the fault.

Precautions

For the voltage scope in which the device works properly, refer to the Hardware Description. If the output of the display voltage command indicates that the current working voltage of the device is out of the scope, adjust the working voltage to ensure the proper running of the device.

For the voltage scope in which the device works properly, refer to the Hardware Description. If the output of the display voltage ipu command indicates that the current working voltage of the device is out of the scope, adjust the working voltage to ensure the proper running of the device.

Example

The actual command output varies according to the device. The command output here is only an example.
