Example for Switching a Fit AP with Factory Defaults to the Fat Mode by One Command

Example for Switching a Fit AP with Factory Defaults to the Fat Mode by One Command

Applicable Scope

This example is applicable to APs with factory defaults. APs work in Fit mode by default.


With factory defaults, the local configuration of an AP is not modified, and the AP has not obtained the new configuration from an AC.

Applicable version: V200R007, V200R008, V200R009 and V200R010

Applicable model: AP5050DN-S, AP2051DN, AP2051DN-S, AP2051DN-E, AP1050DN-S, AD9431DN-24X, AP2050DN, AP2050DN-S, AP2050DN-E, AP4050DN-HD, AP4050DN-E, AP7050DN-E, AP7050DE, AD9430DN-12, AD9430DN-24, AP6150DN, AP6050DN, AP8130DN, AP8030DN, AP4050DN, AP4051DN, AP4151DN, AP4050DN-S, AP8050DN, AP8150DN, AP8050DN-S, AP4051TN, AP6052DN, AP7052DN, AP7152DN, AP7052DE, AP8050TN-HD, AP8082DN, AP8182DN,

Networking Scenario

To use a new AP independently provide Wi-Fi coverage, you need to switch the AP to the Fat mode and deploy services through the web platform or other way.

Connect the AP to a PC through an Ethernet cable in a proper mode, as shown in Figure 4-11.

When the AP supports DC power supply and works with a power adapter, connect the AP to the AC directly through an Ethernet cable. If the AP does not support DC power supply or no adapter is available, supply PoE power to the AP. In this case, connect the AP to the PC through a PoE device.

Quick Configuration

This section helps you quickly configure an AP, without the need to read the entire document. If you are not familiar with the product or operation, read the detailed guidance in the following sections.




Prepare the environment: Configure the IP address of the PC and STelnet, check network connectivity between the AP and PC, and observe indicator states.


Check AP information: On the PC, log in to the AP through STelnet to check the version and working mode of the AP.


Start the switching: Run the ap-mode-switch fat command in the system view to switch the working mode of the AP. The AP then restarts.


Verify the switching: Log in to the AP again and check the working mode of the AP.

Configuration Procedure

  1. Prepare the environment.

    The following is used as an example. Prepare your environment based on site requirements.




    Operating system: Windows 7

    STelnet client: PuTTY (third-party software)

    Warning: The system will reboot and start in fat mode of V200R007C20SPCa00. Continue? (y/n)[n]:y
    Info: system is rebooting ,please wait.................

  4. Verify the switching.

    # Log in to the AP to view AP information. The AP is working in Fat mode.

    login as: admin
    Further authentication required
    Info: Current mode: Fat (working independently).
    Warning: The default country code is CN. Ensure that AP radio attributes comply

An error message is displayed when you run a mode switching command.

[Huawei] ap-mode-switch fat
Error: The fat mode does not exist. To switch to the fat AP mode, run the ap-mode-switch fat tftp/ftp/sftp command. 

The AP is not in factory defaults and therefore cannot be switched to the Fat mode by one click. In this case, switch the working mode of the AP using SFTP. For details, see the related sources.
