SP faulting

Hi, I'm posting this in a new thread because the one where I posted it in has had the original question answered.

I'm trying to attach a DAE2-ATA to a CX3-40f.

My CX has three buses already in use, and I would like to put this DAE2 on its own bus (BE 3) since its 2Gbps.

I have followed the procedure with NST, but everytime I plug the cable into the SP it faults. I don't even plug in the other end.

I'm wondering if its the cables, but I have tried two of them. I had to have them made by a third party cable vendor since the CX3 uses SFP on its end and the older DAE2's use HSSDC1 on the PRI port instead of HSSDC2.

If I plug in a SFP-HSSDC2 cable into the SP it is fine, but obviously that doesn't help me with the DAE2.

Please help. I need this ATA array to implement a backup to disk scheme.
