Installing the Cisco cBR in a Two-Post Rack
The procedure for front mounting a chassis in a two-post rack is similar to the procedure for front mounting
in a four-post rack, except that you cannot use the second chassis installation bracket.
Caution
If you are using a two-post rack, secure the rack to the floor surface to prevent tipping and physical injury,
and avoid damage to the component.
To mid-mount the chassis, follow these steps:
Step 1
Ensure that all screw fasteners on the installed components are securely tightened on the chassis.
Step 2
Ensure that your path to the rack is unobstructed.
If the rack is on wheels, ensure that the brakes are engaged or the rack is otherwise stabilized.
Step 3
(Optional) Install the chassis installation bracket into the rack to support the chassis during installation when you secure
it to the rack.
Step 4
With two or more people, lift the chassis (partially unloaded) into position between the rack posts and rest it on the chassis
installation bracket.
The chassis can be lifted using the two large side handles. You can also use the handles at the rear Power entry area or
by placing your hands under the chassis.
Step 5
After the rear weight of the chassis is resting on the installation bracket, one person can hold it in place while the second
person moves to the rear of the rack to help slide it into place and hold the weight while the rack mount screws are
tightened.
Step 6
Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.
Step 7
Hold the chassis in position against the mounting rails and do the following:
a) Insert a bottom screw into the rack mount ear on each side and use a hand-held screwdriver to tighten the screw to
the rack rail.
b) Insert a top screw into each side rack mount bracket and tighten the screw to the rack rail.
c) Insert a minimum of four screws per bracket on both sides of the chassis.
Step 8
Ensure that all screws on each of the side rack-mount brackets are tightened to the equipment rack before the chassis
installation bracket is removed from the rack.
