  1. Start a TFTP server and the console session.

    Download the boot image ap1g2-k9w7-tar.default to the "Base Directory" set in a running Tftp64 server (Ensure the PC firewall allows incoming and outgoing connections to the TFTP server on port 69).
    Plug in a serial cable to "CONSOLE" port of the access point from PC COM1 port
    Open PuTTY and select "Serial" connection type, leave baud rate (Speed) and other settings as default.
    Plug in an ethernet cable into an ethernet port of a PC from either (a) the ethernet port of the access point, or (b) the "To Switch" port of a running power injector device.
    Manually set the ethernet PC interface IP to the same subnet as the default IP of the Access Point which is 10.0.0.1 and ensure the same IP is selected in the TFTP "Server interfaces" dropdown:
    PC ethernet interface IP settings Tftp settings

  2. Power on the access point.

    Press and hold down the "Mode" button:

  4. Copy all the output from the session into your records.

    Right-click PuTTY's titlebar, from that dropdown menu click on "Copy All to Clipboard"
    Open the file of record certifying the deconfiguration of this device and use CTRL V to paste all the output from PuTTY into that file. Formatting the text with a fixed-width font helps it look more readable.

  5. End the session.

    Turn off/unplug the device and close PuTTy and the TFTP server.
