Hello Peter:

You are right, it was a cabling setup problem. Actually, what we do was 
take a laptop HP 6550B with serial port, connect a cisco console cable 
directly to rj45 SERV MNGT port on T5220.

Worked like a charm, we were able to login via "root" "changeme", 
firmware upgrade and deploy system.

Those usb to serial cables such as Prolific can cause problems sometimes...
