[Beowulf] force factory rest of sfs7000 (topspin 120)

[Brock Palen]

We have a cisco sfs7000 (maybe still under support waiting on cisco)   
also known as a topspin 120, IB switch.

We cannot login with the password we (thought) had it set to. I have  
looked online and find little tonight about forcing the switch back to  
factory defaults without a login.

Serial console works fine, just can't login.  We can screw in firmware  
a little by stopping boot, just don't know what to do from there.  If  
anyone has directions how to force sfs7000 to factory defaults, or  
password recovery help would be great.
