Ah.  2-legged robots will work OK too.

If there isn't a cartridge assignment map, when the operators (who are paying 
attention!) put the cartridges in the I/O door, they use the library panel (or 
the web interface) to tell it  which logical lib to assign that batch of 
cartridges to, then you run a TSM checkin as usual.  

The exact sequence varies depending on whether you have "virtual" I/O slots 
enabled with ALMS, but it's documented in the Operator's guide. 
So you should get the same resulting function as with your 3494.

Operators paying attention when loading them ;-)

Using category codes there are 2-library manager servers. Since only one LM is 
used for offsite, 99.9% of tapes bring checked in are handled by it with bulk 
check-in.
