Overview
This document provides instructions for the addition of sections to the Pass-
Through mechanism (“the mechanism”) in a TL881 MiniLibrary system. It is
intended to be used in conjunction with the Compaq Upgrade Kit, part number
120880–B31
IMPORTANT:
These procedures should be performed by a qualified service technician.
Mechanism Section Covers
The Pass-Through mechanism moves tape cartridges vertically between
TL881 MiniLibrary modules. Each module section is covered by an individual
sheet-metal enclosure. These covers protect the mechanism during shipping
and are an important safety shield during operation.
A separate detachable side plate is part of the cover assembly. During
installation the side plates should be removed on any mechanism sections
located behind a MiniLibrary module; this allows easy access to a cartridge
stranded in transit by a commercial power outage. The remaining portion of
the cover can be removed also from any section behind a module.
IMPORTANT:
Both parts of the covers must remain in place over any section of the
mechanism that is not behind a MiniLibrary module. Any gaps between modules should
remain completely covered.
