Gary,
According to the Spectralogic web site the 2K will support any generation of
AIT tapes and they added AIT-2 support at firmware level 1004.00, AIT-3
support at T1016.00, and AIT-4 support at T2201.00.
We have the Advanced Replacement support option (if there's a problem that
causes a major failure they send us a replacement 10K then we send the old
one back). So when we upgraded they sent us a 10K with AIT-4 and we sent
the old one back. The new library had both upgraded firmware and an
upgraded interface (from Fast Wide SCSI to Ultra2 Wide SCSI (LVD)). The
interface upgrade was necessary to get enough throughput for the AIT-4
drives. Our cost for the upgrade was around 11K but when we first started
exploring it around 16 months ago it was more like 16K.
I imagine for you to upgrade from AIT-1 to AIT-2 wouldn't require anything
more than a firmware upgrade but to go beyond that you'd need the interface
upgrade as well but check with Spectralogic to be sure.
Hope this helps.

Thanks Dave, for the reply. I've only run the tape cleaner through once
each time, and it's worth trying again before I assume hardware problems.
Can a Spectralogic 2000 jukebox be upgraded from AIT-1 to AIT anything else
without requiring new firmware or other changes besides the drives? (No
need to reply if you don't know, I'm adding this in case someone sees it
and knows...) -Gary
