Rack-Mount the Chassis
The rack is a standard Electronic Industries Association (EIA) rack. It is a 4-post-EIA-310-D, which is the
current revision as specified by EIA. The vertical hole spacing alternates at .50 inches (12.70 mm) to .625
inches (15.90 mm) to .625 inches (15.90 mm) and repeats. The start and stop space is in the middle of the
.50-inch holes. The horizontal spacing is 18.312 inches (465.1 mm), and the rack opening is specified as a

You need the following to install the chassis in a rack (4-post EIA-310-D rack):
• #1 Phillips screwdriver
• Firepower 4100 rack-mount kit that contains the slide rails, mounting ears, and screws
Slide rail assemblies work with 4-post racks and cabinets with square slots, round 7.1-mm holes and 10-32-inch
threaded holes on the rack post front. The slide rail works with front to back spacing of rack posts from 24 to
36 inches. The rack-mounting posts need to be 2 to 3.5 mm thick to work with the slide rail rack mounting.
Note
Internal obstructions between rails can make slide rail installation more complicated. Use racks that do not
have internal obstructions between rails for unhindered slide rail installation.
