RS1220 is a dual controller, 12 bay SAS or SATA storage array with Fibre channel connectivity.

USB port is a serial port and not a true USB port as such.

GUI default username and password are “admin” and “password”

Old (defaults?) IP's of the controller ports are
C0 (lower controller) 192.168.1.90
C1 (upper controller) 192.168.1.91
Port 9292

You need to specify the port address too so if you entered it into your browser it would look like

http://192.168.1.71:9292 and http://192.168.1.72:9292
