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 "Safety Instructions" as well as the
safety instructions found in your system’s System Information document 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 have 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.
NOTE:
For instructions on installing the system itself, see "Installing the System in the Rack."
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.
