Compaq TL881 MiniLibrary System Users Guide (May 1999)

Installation 3-25
10. If binding occurs, or if the module is not centered on the Pass-Thru
mechanism, loosen the four screws that secure the slides of the binding
module to the front rails and the four screws that secure the slides to the
rear rails, reposition the slides, then retighten the screws.
11. If necessary, repeat steps 6 and 7 until the module does not bind against
the slides or against adjacent modules.
12. Repeat steps 6, 7, and 8 for all of the remaining modules.
Interfaces and Cabling
Refer to Figure 3-15. The connections required depend on the type of module.
The Expansion Unit always has the SCSI connection to the host for the library
robotics. MiniLibrary Base Modules have a separate SCSI connection to the
host for each drive*, but the SCSI connectors for the robotics should not be
used. The portion of the library robotics that is located in the MiniLibrary Base
Modules is controlled by the Expansion Unit through a cable connected to the
Expansion Interface connector on each module. Each module has a separate
AC power connection.
*IMPORTANT: In principle it is possible to daisy-chain the SCSI connections for multiple
drives, to save SCSI controllers. Compaq strongly recommends against this practice
because it may severely limit the data throughput performance and reliability of the
library.
