Chapter 5 Installing a Cisco Nexus 7018 Chassis
Installing the Bottom-Support Rails on the Rack
• Description of the problem and how it affects the installation
Installing the Bottom-Support Rails on the Rack
The bottom-support rails hold the Cisco Nexus 7018 chassis on the rack or cabinet. To maximize the
stability of the rack, you must attach these rails at the lowest possible rack unit (RU).
The prerequisites, tools, and process for installing the bottom-support rails are included in the following
topics:
• Prerequisites for Attaching the Bottom-Support Rails, page 5-4
• Required Tools and Equipment, page 5-4
• Attaching the Bottom-Support Rails, page 5-4
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 Cisco Nexus 7000 Series system. Also, you must have the
bottom-support rail kit, which ships with the Cisco 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).
Required Tools and Equipment
You need the following tools and equipment to attach the bottom-support rails:
• Number 1 Phillips-head screwdriver with torque capability.
• Rack-mount kit (shipped with the accessory kit). Table 5-1 lists the items in the rack-mount kit.
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.
