PASSWORD RECOVERY PROCEDURE
This document 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 document will explain 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:
4. 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.
5. Power on the switch. After the boot image is 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.
6. In the “Password Recovery Mode” only the following commands can be used.
