Rack-mount the chassis using slide rails

This procedure describes how to install the Secure Firewall 6100 series in a rack using slide rails. It applies to all models of the Secure Firewall 6100 series. You use the pegs on the chassis to secure the slide rail. See Product ID numbers for a list of the PIDs associated with racking the chassis. You can install the optional cable management bracket on all models of the Secure Firewall 6100 series.

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 minimum of 17.75 inches (450 mm).

Slide rail assemblies work with four-post racks and cabinets with square slots, round 7.1-mm holes, #10-32 threaded holes, and #12-24 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.
