The Sun Blade 2000 has room for a tape drive and a DVD-ROM drive
(both 50-pin SCSI) inside, along with a floppy and/or a smart-card
reader. (Both of the last two if you don't have the tape drive
installed.) The cable includes the terminator at its end (just past the
DVD-ROM drive), so as long as you're using the standard cable, you are
fine as far as termination is concerned. BTW -- that SCSI bus is used
*only* for the DVD-ROM and the optional tape drive. The floppy and the
Smart Card reader both have their own cables going to the system board.
There is also an external SCSI bus -- 68-pin -- on the back.
This talks to *nothing* internal to the box.
And the two internal disks are FC-AL (Fibre Channel), not SCSI,
so they don't argue with either SCSI bus.
Assuming that the system sees the DVD-ROM drive, then the
internal SCSI bus is good.

What's the Sun barcode number for this? I can't seem to find a
Sony tape drive of any flavor in the FEH (Field Engineer's Handbook).
Assuming that we are talking about DAT drives, I find Archive, Conner,
Seagate, HP, and some autoloaders. No Sonys. (Perhaps look up the man
page for your drive on the Australian collection of Sun FEH pages.
O.K. A look for the model on Google shows that it is an AIT
drive, too new for the last printed FEH to cover.
This web site documents the switch settings:
================================================== ====================
http://stason.org/TULARC/pc/tape-dri...-SDX-300C.html
================================================== ====================
and it appears to be a 68-pin SCSI, so it would have to go in an
external housing.

Most of the switch elements and jumpers shown by the above web
site are "Factory configured -- do not alter". The remaining ones are:
(1) TERMPWR (jp1 pins 9 and 10)
(2) Compression enable (SW1/7)
(3) Parity enabled (SW1/8)

Oops! Not nearly as reliable as the Exabyte Mammoth and
Mammoth-2 drives, I guess. :-(
Good Luck,
