Two 192's Recognized but not...

[TCDet]

That's what I get for working on Sunday.
The below issue has been resolved.
I (Ooops) Attached the 192's to the last HDa card rather than the Core card.
Admin may delete this post after you get a nice chuckle.....
Hi.
I have system That was working.
Now I had to change out 1 G5 for a newly repaired one (Power-supply)
After changing cards and internal drives....
But up fine, Digi test Fine (HD3).
Restart, Launch Pro Tools (PT's8)
The two 192's don't seem to loop sync but seem to be recognized.
"Unable to find interface attached to first HD card..."
With both on and cabled (Unchanged from previously working Mac/System)
I click on OK to rescan.....
Now, both 192's LED's flash showing they're being seen but Sync-Loop never lights up.
• I check / reseat all sync cables
• Uninstalled and reinstalled Pro Tools 8 (then 8cs1) thinking PT's 8 Was install in the Loaner computer and my be missing something new.
Restart (Cold start with 192's off) wait until this same message appears. Power on #1 then #2 192, click on OK to rescan... Sill no go.
Just the SR & Sync Mode LED's flash on both units. Loop master not engaging.


Working pre loaner Mac: Dual 2.3 G5 PPC.
Hard drives (Internal) Main and Clone. OS 10.5.5
The system drives and HD3 cards Moved into the loaner Mac when my power supply died. All working and at the time I was in Leopard 10.5.4 PT's 7.4.2, Updated successfully to PT's 8 in the the Loaner Mac.
Newly repaired Mac: G5 Dual 2.7 PPC.
Swapped/ installed my internal drives and HD3 Cards.
Reconnected as described above.


? Could a lesser power-supply cause this?
The Apple store did not supply me with details on their repair.

Thoughts?
Thank you.

I'll try some alternate cables today and my go back and see if the loaner Mac is remains working.

Have you tried this with just one interface and swapping cables, to determine if it's a cable or interface that may be causing the problem?
