Rack Requirements
CAUTION: The 42-U rack meets the specifications of American National
Standards Institute (ANSI)/Electronic Industries Association (EIA) standard
ANSI/EIA-310-D-92, Consumer Electronics Association (CEA) Standard CEA-310-E,
International Electrotechnical Commission (IEC) 297, and Deutsche Industrie Norm
(DIN) 41494.
Before You Begin
WARNING: Before you begin installing your rack, carefully read "Important
Safety Information", as well as the safety instructions that came with the rack.
WARNING: When installing multiple systems in a rack, complete all of the
procedures for the current system before attempting to install the next system.
WARNING: 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, rough surfaces, or ramps where loss of cabinet control may occur.
Extend the leveling feet for support and to prevent the cabinet from rolling.
WARNING: Avoid rolling the rack cabinet over rough surfaces. Hard impacts to
the casters could cause them to break, and the rack could become unstable and
tip over.
WARNING: Do not attempt to move your rack with components installed. If you
move a fully loaded rack on a slightly uneven floor surface, the rack may become
unstable and tip over.
Important Safety Information
Observe the safety precautions in the following subsections when installing
your system in the rack.
WARNING: 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.
WARNING: For stability, you must ensure that a minimum of 50 lbs. is installed in
the bottom 3-U spaces of the rack cabinet.
