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:
1.
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.
2.
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.
