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:
•
•
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.
Note 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.
Note When you install a Cisco Nexus 7009 chassis with center-mount brackets, you must always install the
chassis onto center-mount bottom-support rails.
Do not remove the center-mount brackets when a chassis is installed on them. They are required at all
