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.
