[rescue] How to "find" Cisco 3620?

[Thomas Gallaway]

I have similar things going on. Have a cisco 2900 10/100 switch and 
actually
the machine boots up but the console port just show's me crap. But then 
after
a minute or so the switch crashes and show's me a error message just 
perfectly
with no jibbrish. So I am assuming the switch itselfe is shot, and not 
just the
serial port as it has the ability to show me something usefull when it 
crashes.

But yes 9600/n/8/1 should do the trick. If not, good luck.
