Installing Chassis Installation Brackets - Cisco cBR-8 Installation Instructions Manual

Procedure
Step 1 Mark and measure the distance between two holes on the left and right mounting rails.
The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).
Measure the pairs of holes near the bottom, middle and top of the equipment rack to ensure that the rack posts
Note
are parallel.
Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the equipment rack.
The space must be at least 17.7 inches (45 cm) to accommodate the chassis which is 17.45 inches (44.3 cm) wide and fits
between the mounting posts on the rack.
What to Do Next
Install chassis installation brackets.

Installing Chassis Installation Brackets

Each chassis is shipped with two chassis installation brackets in the accessory kit. These brackets aid in installing a chassis into a
19-inch rack and are used as a support base to vertically position and set the chassis before the rack mount screws are installed.
Procedure
Step 1 Determine the position in the rack where you want the chassis to be mounted. If you are mounting more than one chassis
in the rack, then start from the bottom or the center of the rack. Hold the chassis installation bracket where the chassis
bottom will be positioned vertically in the rack.
Step 2 Secure the chassis installation bracket to the front rails with rack mount screws.
