Chapter 3 Installing the Router
Installing a Router
Installing the Chassis in a Rack
This section explains how to install Cisco 12006 and Cisco 12406 Routers in a
rack. This procedure assumes you have unpacked the router using the
Cisco 12006 and Cisco 12406 Router Unpacking and Repacking Instructions
(Document number 78-16104-xx) posted on the outside of the shipping container.
You mount the chassis in the equipment rack by setting the chassis in position
against the rack rails and then securing it to the rack or optional center-mount
brackets with screws through holes in the rack-mounting flanges on either side of
the chassis. To accommodate racks with different hole patterns in their rails, the
chassis rack-mounting flanges have two groups of eight oblong screw holes on
either side. (See Figure 3-3.) The mounting holes in the chassis flanges are spaced
so that one mounting hole in each hole group aligns with a hole in the rack rail or
optional center-mount bracket. By using the corresponding mounting hole (in the
same hole group) on the opposite side of the chassis, you can level the chassis in
the rack.
