Installing the Bottom-Support Rails on the Rack
You can use the following two types of bottom-support rails to install and hold a Cisco Nexus 7009 chassis
to its rack:
• Front-mount bottom-support rails
• Center-mount bottom-support rails (part number N7K-C7009-CMK)
Typically, you use the two front-mount bottom-support rails in the Bottom Support Kit (part of the Cisco
Nexus 7009 Accessory Kit or ordered separately as part number N7K-C7009-BSK). If you additionally ordered
the Center Mount Kit (part number N7K-C7009-CMK) for centering the chassis on a two-post rack, you will
receive an additional kit with two center-mount bottom support rails and two center-mount rail mounting
brackets. You must install either the front-mount bottom-support rails or the center-mount bottom-support
rails before installing the chassis.

If you are installing three Cisco Nexus 7009 chassis with front-mount brackets in a 42-RU rack and you can
safely position the bottom chassis at the lowest RU using a mechanical lift, you can fasten the chassis directly
to the rack or cabinet with the maximum number of screws. After you install the bottom chassis, you can slide
the additional chassis onto the fully installed lower chassis (without using additional bottom-support rails)
and then fasten the upper chassis to the rack. This process enables you to install three 14-RU Cisco Nexus
7009 chassis in a 42-RU rack. If you do not need to install three chassis in a 42 RU rack, we recommend that
you always install each chassis on its own set of bottom-support rails.
