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.
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.
Complete these steps to reset the password:
2. Power on the Switch. After the UART init 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.
