The following sections describe how to prepare the TL881 and TL891 DLT
MiniLibraries for shared SCSI bus use in more detail.

Bus Usage
A TL881 or TL891 DLT MiniLibrary tabletop model or a rackmount base
unit may be used standalone. You may want to purchase a rackmount base

______________________ Note _______________________
To achieve system performance capabilities, we recommend
placing no more than two tape drives on a SCSI bus, and also
recommend that no shared storage be placed on the same SCSI
bus with a tape library.
The topics in this section provide information on preparing the TL881 or
TL891 DLT MiniLibrary tabletop model or rackmount base unit for use
on a shared SCSI bus.
