Rack Installation Guide

Before You Begin
Before you begin installing your system in the rack, carefully read "Safety
Instructions" on page 5, as well as the safety instructions found in your
Product Information Guide for additional information.
CAUTION:
When installing multiple systems in a rack, complete all of the
procedures for the current system before attempting to install the next system.
CAUTION:
Rack cabinets can be extremely heavy and move easily on their
casters. They do not have brakes. Use extreme caution while moving the rack
cabinet. Retract the leveling feet when relocating the rack cabinet. Avoid long
or steep inclines or ramps where loss of cabinet control may occur. Extend
the leveling feet for support and to prevent the cabinet from rolling.
NOTE:
For instructions on installing the system itself, see "Installing the System
in the Rack" on page 18.
Important Safety Information
Observe the safety precautions in the following subsections when installing
your system in the rack.
CAUTION:
You must strictly follow the procedures in this document to protect
yourself as well as others who may be involved. Your system may be very large
and heavy and proper preparation and planning are important to prevent injury
to yourself and to others. This precaution becomes increasingly important when
systems are installed high up in the rack.
CAUTION:
Do not install rack kit components designed for another system.
Use only the rack kit for your system. Using the rack kit for another system may
result in damage to the system and personal injury to yourself and to others.
