Chapter 3 Installing a Cisco Nexus 7009 Chassis
Installing the Bottom-Support Rails on the Rack
Attaching the Front-Mount Bottom-Support Rails
To maximize the stability of the rack, you should install the chassis as low as possible on the rack. Install
the heaviest chassis first at the bottom of the rack. If you install a second chassis in the same rack, install
it immediately above the lower chassis if there is enough vertical space.
To attach the front-mount bottom-support rails to a two- or four-post EIA rack, follow these steps:
Step 1 Position one of the two front-mount bottom-support rails at the lowest possible RU on the rack. If you
are installing a chassis above another Cisco Nexus 7009 chassis, position the rail 26.25 inches (66.7 cm)
(15 RU) above the bottom-support rails for the lower chassis as shown in
Figure 3-1 .
Note When installing the chassis without bottom-support rails, you can skip this step.
Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to
ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest
component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in
the rack.
