4. Referring to Figure 3-6, locate the tensioner ramp in the base section.
Compress the spring until the hole in the tensioner ramp is aligned with
a hole in the base section. Insert an 0.050" Allen wrench or a paper clip
through the holes. This sets the idler pulley for zero belt tension.
5. Referring to Figure 3-8, loosen the four screws on the belt block far
enough to pull the ends of the belt free of the block. Pull the belt free of
the motor drive assembly and the base section and set the belt aside.
6. Turn the Pass-Thru mechanism over and support it so that neither the
motor nor the flange at the bottom of the base assembly is touching the
work surface.
7. Referring to Figure 3-1 and Figure 3-4, remove the eight screws holding
a pair of tie bars in place. Separate the Pass-Thru mechanism at that
joint.
8. You may now add sections as needed and install a new belt as described
in the sections entitled Assembling the Pass-Thru Mechanism and
Installing the Belt.
Mechanical Installation of the Expansion and
MiniLibrary Base Modules
The Expansion Unit and MiniLibrary Base Module(s) may be rackmounted in
either a Compaq rack, a standard 19" EIA/RETMA rack (with a depth of 24-
30") or a StorageWorks (SW500, SW600, or SW800) metric rack using metric
conversion brackets. Both rack types require two initial steps:
1. Separating the rack-slides.
2. Attaching the mounting-brackets.
This section describes these common rackmount instructions, followed by
rack-specific rackmount instructions. The cabling and configuration
procedures for all rackmounted MiniLibraries are described in the section
entitled Interfaces and Cabling.
Follow the directions in the shipping container to unpack the module(s). Save
the packing materials for re-use in case you need to return the module(s) for
repairs.
The Expansion Unit and the MiniLibrary Base Module come with the basic
RETMA/Metric slide rack set installed on either side. Note that the Compaq
rackmount kit is packed with the unit. The slide is attached to the MiniLibrary
Base Module enclosure by means of three screws through the inner slide.
Remove the packing tape from the slides, and separate each set of slides as
follows:
