How to reset a HP SuperStack 3 4200 26-port Switch

[kyecall]

I would like to reset a HP SuperStack 3 4200 26-port Switch, but I already forgot the IP of the switch.

I tried to use console to connect the switch,  and the connection set up is:

Speed: 9600

Data bits: 8

Stop bits: 1

Parity: None

Flow control: None

But also cannot connet the switch.

How can I reset this HP SuperStack 3 4200 26-port Switch?

Hi

The old 3Com products have:

Speed: 19200

Data bits: 8

Stop bits: 1

Parity: None

Flow control: None

Enter the Bootrom menu and delete the config file. that's it.

Already reset it. Cause the console cable need to use non modem cable.
