Hi, forgive the rudimentary question, but here is the issue I am facing.
I just got a brand new switch and was configuring this and somehow I am not able to get into this via telnet or console. I was hoping to get into ROMMON mode and just redo the config but I don't seem to be able to get this to come up. I have used control break using putty as the terminal but I don't seem to get anywhere like I have doing this on other Cisco devices. Any ideas or suggestions on how to get this back so I can just redo the config on it?

reboot the switch while holding the mode button (a few swconds, until the status light is steady)
release the mode button, you should see a promtk "switch>" - if not repeat the power cycle and hold the mode button longer than before.
enter: flash_init
enter: rename flash:config.text flash:config.old
(Do not use line editing commands like delete, cursor right or left etc...
you can easily mess up the filename - get it right the first time or better power-cycle again)
reboot again normally... you should see after a while the autoinstall-script "do you want to configure..." , quit the auto-install ("N" or "crtl-Z")
with the command "more flash:config.old" you can read the old startup config and use it as a base for your new (corrected) configuration.
