Resetting a 3Com® SuperStack® II Switch 3300
I just bought an used 3Com® SuperStack® II Switch 3300. Is there a way to reset it? Since I don't know it's password and Im quite insecure that I would get it from the seller. Also I wonder what the default IP is if I reset it.
try connecting via serial console cable
from there you should be able to access the switch, and reset the defaults as well as the pasword

Is there a way using the ethernet interface instead of the console port?

1. firmware (for a Superstack II 3000 like I have) the url is http://support.3com.com/software/superstack_ii_switch_3300.htm ;
2. a null modem cable
3. a TFTP Server software you can download it from 3com called 3CServer (make sure you set the TFTP folder where the firmware file is located)
Once you have all this in hand do the following.
1. Connect the null-modem cable, configure Hyper Terminal for windows users to the com port you have connected, normal com setting N-8-1 none and VT100, connect to switch (login should appear if not don't worry console may be disable)
2. configure and start your TFTP Server
3. on the switch push the reset button 2 seconds
4. wait 3 seconds
5. push reset button again for 1 second
6. you should see the prompt after a few seconds at the prompt line type the following commands
F ls3k3_23.slx (firmware file name) "press enter"
B IPAddress of TFTP Server "press enter"
After firmware update the switch will reboot and the passwods will fall back to factory default.

There is no reset button on the switch
I have also SuperStack II 3300 and I am trying to reset it to factory default settings, because i don't know the password for admin or security -account (they have been changed by the previous owner). Also the seller did not know password to these accounts. At the moment i am using the switch with manager -account.
The problem is, that when I try to reset the switch in system-menu, there is no "initialize" and the switch don't recognize the command. There is just "reset" but it does not affect login names and passwords. Any ideas?
