114 Library Installation and CRU Replacement
d. Next, install the shelf’s front studs in the rack’s front mounting holes.
e. If the studs do not reach the mounting holes, pull the front of the shelf toward you to extend it
to the necessary length. Hold the base of the shelf with one hand, and pull the extensible part
of the shelf with your other hand.
f. Fasten a thumbnut to the end of each stud. Secure the rack tightly, so that the ferrule fits snugly
within the hole in the rack.
4 Visually make sure that both shelves are level, and that they are aligned properly within the rack.
5 Make sure that all thumbnuts are fastened tightly. Some thumbnuts may have loosened during
installation.
Preparing Modules for Rack Installation
1 Power off your library and disconnect all power cords, network data cables, and module-to-module
cables.
2 Remove all tape cartridges, tape drives, and power supplies from the library modules. The modules are
much easier to lift into the rack without the additional weight of these components.
Extending the shelves can be difficult, but they are designed to be resized
by hand. Do not use tools to resize the shelves, and never take them apart.
