4-Post Rail Installation

This procedure describes how to prepare and install the rail assembly into the equipment rack
for 4-post installations.
To install the rail assembly for 4-post installations:
1. Assemble the slide rails:
a. Loosely attach Rail__C to Rail_A. The location and mounting method depends on
how far Rail_C must be extended to fit the rack. Use the following guidelines to
properly mount Rail_C to Rail_A:
• Approximate the installation length by lining up the front and rear mounting
faces against the vertical equipment rails.
• Install screws into the mounting points on the opposite ends on the slotted hole
on Rail_C. Be sure to use at least a total of (3) screws.

Note: If the Rail_A assembly is fully extended, you can retract it by activating the release
tab inside the rail.
2. Mount the slide rail assemblies into the four post rack.

Note: The rack screws used in this step are not included with the slide rail kit as they are
rack-specific. See your equipment rack installation guide for more information on screw
sizing.
a. Align the assembled Rail_A against the equipment rack and mount to the outside
face of the rack using (2) rack screws. Do not fully tighten! The Rail_A bracket will be
tightened after the appliance is secured in the rack.
