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 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:
To attach the front-mount bottom-support rails to a two- or four-post EIA rack, follow these steps:
SUMMARY STEPS
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
Front-Mount Bottom-Support Rails, on page
2. Use a Phillips screwdriver to screw in two or three (three are recommended if you have three screw holes)
M6 x 19 mm or 12-24 x 3/4 in. Phillips screws on the front end of each bracket (using a total of 6 screws
for both brackets) as shown in .
3. Align the crossbar to the lower back of the two bottom-support rails and use two M4 x 8 mm screws to
attach it to each rail (one screw for each rail).
