Jaime,

  I'm afraid that the bit about the wiring and connectors lost me? To what are
you referring?

As for extending the SCSI cable outside of the box, it's not really set up for
that (although it could be hacked to be that way in a lab). One of the major
issues would be getting the cable through a bulkhead and maintaining EMI rating
for the system. The internal SCSI is run through etch in the module to a cable
connector near the drive plate. From there it cables up to the drives. Not the
best orientation to use for going back outside of the system enclosure.

I hope that's a little clearer.

				Thanx,
				  AJ
