Installation Methods
The Cisco cBR-8 router can be either mounted on the rack at the front or in the middle. Also, you can mount
the router on a standard 19-inch-wide four-post equipment rack unit or a two-post rack unit.
The Cisco cBR-8 router is usually shipped fully loaded. The fully configured system weighs approximately
430 lb. You must remove the components from the chassis to make the chassis lighter for the rack installation.
Remove all power supplies, supervisor cards, line cards, rear PIC cards, and fan modules, before rack-mounting
to reduce the weight to approximately 117 lb. For instructions on how to remove the components, see the
monitoring sections.
Note
Make sure that you place the cards and modules in an anti-static bag until you install the chassis in the rack.
Note
Verifying Rack Dimensions
Before you begin
Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your
equipment-rack to verify that the rack conforms to the measurements shown in the following figure.
