• Always load the rack from the bottom up, and load the heaviest item in the rack first.
• Make sure that the rack is level and stable before extending a component from the
rack.
• Use caution when pressing the component rail release latches and sliding a component
into or out of a rack; the slide rails can pinch your fingers.
• After a component is inserted into the rack, carefully extend the rail into a locking
position, and then slide the component into the rack.
• Do not overload the AC supply branch circuit that provides power to the rack.
The total rack load should not exceed 80 percent of the branch circuit rating.
• Ensure that proper airflow is provided to components in the rack.
• Do not step on or stand on any system/component when servicing other
systems/components in a rack.
Installation Instructions
This installation guide provides instructions for trained service technicians installing one or
more systems in a rack cabinet. The RapidRails™ rack kit can be installed in all Dell™ rack
cabinets, and the VersaRails™ rack kit can be installed in most industry-standard rack
cabinets. The procedures for installing both RapidRails and VersaRails rack kits are similar.
One rack kit is required for each system to be installed in the rack cabinet.
CAUTION: Do not attempt to 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.
NOTE: If your system is a tower version, you must first convert the system to a rack version
using a tower-to-rack conversion kit. Instructions for installing this kit are included in this
document.
RapidRails Rack Kit Contents
The RapidRails rack kit consists of one pair of RapidRails mounting rails (see Figure 1-1).
