Recovering the Password of an AT

An AT device supports only one local user account, which can be a console, Telnet, or SSH account. If the password is lost, enter the Uboot view and recover the default user name and password.

• You must restart the device to enter the Uboot view, which results in service interruption. Back up service configuration and perform this operation in off-peak hours.
• Do not power off the device during the operation.

1. Use a serial cable to connect a PC to the device and restart the device. When the message "Press f or F to stop Auto-Boot" is displayed, press F and enter the password to enter the Uboot view.

   For details on how to connect a PC to the device with a serial cable, see Logging In to a Device Through the Console Port.

   The BootROM password may vary in different software versions. For details, see List of Default User Names and Passwords.

2. Run the defaultuser command to recover the default user name and password.

   ar7240> defaultuser
   Start setting whether to Change Password.....
   Current Bootup Change PW is N 
   Do you Want To Change The Default password, Y or N : Y
   ar7240>

3. Run the reset command to restart the device.

   ar7240> reset
   Resetting...

4. After the device restarts, use the default user name and password to log in and set a new user name and password. The following example sets the user name to huawei and password to huawei@123.

   <AT815SN> system-view
   [AT815SN] local-user huawei password cipher
   New Password(<8-16>/<56>): 
   Confirm Password:
   [AT815SN] quit

5. Run the save command to save the configuration so that the new password will not be lost after a system restart.
