Installing a rack kit involves performing the following tasks in their numbered order: 

1. Removing the rack doors 

2. Select an installation location within the rack 

3. Installing the RapidRails slide assemblies in the rack 

4. Installing the system in the rack

5. Installing the cable-management arm

6. Routing cables

7. Replacing the rack doors

See the procedures for removing doors in the documentation provided with your rack cabinet.

You must allow 1 U (44 mm, 1.75 inches) of vertical space for each InfraStruXure Central Standard 
Edition system or 2 U (88 mm, or 3.5 inches) of vertical space for each InfraStruXure Central Enterprise 
Edition system you install in the rack. Rack cabinets that meet EIA-310 standards have an alternating 
pattern of three holes per rack unit with center-to-center hole spacing (beginning at the top hole of a 1-U 
space) of 15.9 mm, 15.9 mm, and 12.7 mm (0.625 inch, 0.625 inch, and 0.5 inch) for the front and back 
vertical rails (see Figure 1-3). Rack cabinets may have round or square holes. The RapidRails™ rack kit 
can be installed without tools in manufacturer’s rack cabinets that have square holes. VersaRails™ rack 
kits, which are designed for use with rack cabinets that have round holes, are available for purchase 
separately. 

1. At the front of the rack cabinet, position one of the RapidRails slide assemblies so that its mounting-

bracket flange fits between the marks or tape you placed on the rack (see below). The top mounting 
hook on the slide assembly’s front mounting bracket flange should enter the top hole between the 
marks you made on the vertical rails. 

2. Push the slide assembly forward until the top mounting hook enters the top square hole that you 

placed a mark just above on the vertical rail, and then push down on the mounting-bracket flange 
until the mounting hooks seat in the square holes and the push button pops out and clicks (see 

• Because of the size and weight of the rack cabinet doors, never attempt to remove or 

install them by yourself. 

• Store the two doors where they will not injure someone if the doors accidently fall over.
