Rack Installation Guide

Four-Post Rack Installation
Before attempting this installation, you should read through this entire procedure carefully.
Before You Begin
Before you begin installing your system in the rack, carefully read the safety instructions found at
the beginning of this guide, as well as the safety instructions found in your system’s 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 the casters. The cabinet has no
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.
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 becomes increasingly important
when systems are installed high up in the rack.
Rack Stabilizer Feet
CAUTION:
Installing systems in a rack without the front and side stabilizer feet installed could cause
the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore,
always install the stabilizer feet before installing components in the rack.
CAUTION:
After installing systems in a rack, never pull more than one system out of the rack on its
slide assemblies at one time. The weight of more than one extended system could cause the rack to tip
over and cause injury.
The stabilizer feet help prevent the rack from tipping over when a system or other component is
pulled out of the rack with the slide assemblies fully extended. Refer to the documentation
provided with the rack cabinet for instructions on installing and anchoring the stabilizer feet.
Recommended Tools and Supplies
You may need the following tools and supplies to install the system in a four-post rack:
• A #2 Phillips screwdriver (for installing VersaRails slide assemblies)
• Masking tape or a felt-tip pen, for use in marking the mounting holes to be used
