Appendix F
Unit Case Assembly
This appendix:
• Describes the unit case
• Describes how to install the unit case into a 19-inch rack.
F.1 Unit Case
The unit case design facilitates quick access to the interior strappings as well as
easy installation into a 19-inch rack.
F.2 Installation of the Unit Case into a 19-inch Rack
The height of the unit is 1U (1.75 in); the width of the unit is slightly less than half
the available mounting width. A rack adapter kit, RM-17, is available for installing
either a single unit or two units side by side in the 19-inch rack.
Disconnect AC power before opening the unit.
Installing a Single Unit
Rack adapter components for installing a single unit include one short bracket and
one long bracket. Each bracket is fastened to the side walls of the unit by two
screws (with flat washers) which are inserted into the two front holes on the side
wall (The unit is supplied with nuts already in place on the inner side wall). Note
that the short bracket fastens to the left side of the unit, and the long bracket to the
right side of the unit. See Figure F-1. Installing a Single Unit
Installing Two Units
Rack adapter components for installing two units include: two long side rails (one
for each unit) that slide into each other fastening the two units together, and two
short side brackets which hold the two units in the 19-inch rack. See Figure F-2.
.
Once the brackets are fastened to the side walls, the unit is ready for installation in
the 19-inch rack. Place the unit in the rack and fasten the brackets to the side rails
of the rack by means of the two screws situated on each side (not included in the
kit).
