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, which is in the
accessory kit that ships with every Cisco Nexus 7009 chassis. If you ordered the chassis for an
installation that centers the chassis on its rack, the chassis will ship with two center-mount bottom
support brackets and two center-mount brackets in the Center Mount Kit. 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
Note
can safely position the bottom chassis at the rack 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 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 bottom-support rails.
When you install a Cisco Nexus 7009 chassis with center-mount brackets, you must always install the
Note
chassis onto center-mount bottom-support rails.
Caution Do not remove the center-mount brackets when a chassis is installed on them. They are required at all
times for holding a center-mount chassis to the rack.
