Rack Installation Instructions

This installation guide provides instructions for trained service technicians installing a 48-unit (U) rack. Information includes assembling the rack, coupling two 48-U racks, and routing cables through the rack. The 48-U rack can be installed using the recommended tools.

Before attempting this installation, you should read through this entire procedure carefully.

Rack Requirements

CAUTION: The 48-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.
