Are you sure this will work?  It looks to me, this thing is to connect  
SCSI devices to an iSCSI initiator.  I would think the bridge needs to  
be an initiator to connect to iSCSI storage.

You could rip the LED out of the ATTO and connect the sockets to the  
TT-LED, if you can live with it being on when there is no activity.   
Or glue some reversing logic to that.
