I've gotten hold of a D-Link DGS-3324SR that's going to replace my old dumb switch at home. Problem is that the seller can't remember the passwords, and D-Link give me the backdoor account without some kind of a reciept. Is there a way of resetting this thing without using the backdoor account, or a way to generate the backdoor password? D-Link said that it's a combo of the MAC and possible the name of the switch.

This appears to be the user manual to the device-

According to the manual, if you can do a hard reset on the device (by pressing a physical reset button), it should restart with no username or password. pg 25

Hey, thanks for the answer. There are no physical reset buttons on this device. I even checked inside for jumpers and whatnot. Where in the manual did you read this? (It's a beast) – alu Jul 6 '12 at 14:18
It talks about the username and password on pg 25 – Sepero Jul 6 '12 at 15:55

It is possible to reset this device, if you could manage to get it into a Stack as a slave device.

You need another D-Link DGS-3324SR with a higher Mac-Adresse or you have luck and the box priority is higher than your Commander Switch

This is the procedure to reset admin password with physical access to the switch.
Link to manual page 327

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 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.
Boot Procedure  V1.00.009

  Power On Self Test ........................................ 100% 
  MAC Address

  Please Wait, Loading V1.01.012 Runtime Image .............. 100%

In the "Password Recovery Mode" only the following commands can be used.
