Appendix B – 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:

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 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.
