Appendix A – Password Recovery Procedure
This chapter describes the procedure for resetting passwords on D-Link switches. Authenticating any user who
tries to access networks is necessary and important. The basic authentication method used to accept qualified
users is through a local login, utilizing a Username and Password. Sometimes, passwords get forgotten or
destroyed, so network administrators need to reset these passwords. This chapter explains how the Password
Recovery feature can help network administrators reach this goal.
The following steps explain how to use the Password Recovery feature on D-Link devices to easily recover
passwords.
Complete these steps to reset the password:
•
For security reasons, the Password Recovery feature requires the user to physically access the device.
Therefore this feature is only applicable when there is a direct connection to the console port of the device.
It is necessary for the user needs to attach a terminal or PC with terminal emulation to the console port of
the switch.
•
Power on the switch. After the runtime image and UART init are loaded to 100%, the switch will allow 2
seconds for the user to press the hotkey [^] (Shift + 6) to enter the "Password Recovery Mode." Once the
switch enters the "Password Recovery Mode," all ports on the switch will be disabled and all port LEDs will
be lit.
