How to Factory Reset Allied Telesis AT-9000/24 Switch

switch

I just got a Allied telesis AT-9000/24, and after connecting it and getting to web interface I noticed that the username and password has been changed. So is there a reset switch on the inside or do I need one of those rs-232 to usb convertors to access the terminal and reset it through that way?

The only things I noticed that could be connected as a reset switch said GND and RJ4. None of them sound like a reset switch to me and don't want to brick the switch by connecting them via a wire.

If required I can post some pictures of the board.

There doesn't appear to be any hardware method to reset the software to the factory default. According to the manual, you will need to connect to the switch and reset it through software:

Returning the AT-S84 Management Software to the Factory Default Values

This procedure returns all AT-S84 management software parameters to their default values and deletes all tagged and VLANs on the switch. The AT-S84 management software default values are listed in Appendix A, ”AT-S84 Default Settings” on page 319.

Caution

This procedure causes the switch to reboot. The switch does not forward network traffic during the reboot process. Some network traffic may be lost.

To return the AT-S84 management software to the default settings, perform the following procedure:

  1. From the Main Menu, type T to select Switch Tools.

    The Switch Tools Configuration Menu is shown in Figure 11 on page 50.

  2. From the Switch Tools Menu, type R to select System Reboot to start the reboot.

    The System Reboot menu is shown in Figure 12 on page 51.

  3. Type O to select Set Reboot Option.

    The following prompt is displayed:

    Select reboot option (F/I/N)>

  4. Type F or I to select one of the following:

    F (Factory Default)

    Resets all switch parameters to the factory default settings, including IP address, subnet mask, and gateway address.

    I (Reset to Defaults Except IP Address)

    Resets all switch parameters to the factory default settings, but retains the IP address, subnet mask, and gateway settings. If the DHCP client is enabled, it remains enabled after this reset.

    Note Option N is described in “Rebooting the Switch” on page 50.

  5. Type R to select Start Reboot Process.

    The following prompt is displayed:

    Are you sure you want to reboot the system (Y/N)>

  6. Type Y to start the reboot process.

    The switch returns its operating parameters to the default values and begins to reload the AT-S84 management software. This process takes approximately one minute to complete. You can not manage the device during the reboot. After the reboot is finished, you can log in again if you want to continue to manage the device.
