Prerequisites for Attaching the Bottom-Support Rails
Before you can attach the bottom-support rails, you must fully install the rack or cabinet, and should, for
maximum stability, bolt the rack or cabinet to the concrete subfloor. If anything lighter than the Cisco
Nexus 7018 system is already installed in the rack, you should make sure that it is positioned above
where you will be installing the Nexus 7000 Series system. Also, you must have the bottom-support rail
kit, which ships with the Nexus 7000 Series accessory kit. The distance between the front and rear
mounting brackets on the rack or cabinet must be between 24 and 32 inches (61.0 and 81.3 cm).

You need the following tools and equipment to attach the bottom-support rails:

Attaching the Bottom-Support Rails
To maximize the stability of the rack, you should install the chassis as low as possible on the rack. Install
the first system at the bottom of the rack. If you install a second system in the same rack, install it
immediately above the lower system if there is enough vertical space. If you are planning to install
another system in the rack, make sure that the heaviest system is installed first at the bottom of the rack.
