Installing a Cisco Nexus 7010 Chassis
Attaching the 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 system first at the bottom of the rack. If you install a second system in the same rack, install it
immediately above the lower system 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 bottom-support rails to a four-post EIA rack, follow these steps:
Step 1 Position one of the two adjustable bottom-support rails at the lowest possible RU. If you are installing a chassis above
another Cisco Nexus 7010 chassis, position the rail 36.75 inches (93.4 cm) (21 RU) above the bottom-support rails for
the lower chassis as shown in
so that it stretches from the outer edges of the front and rear vertical mounting rails. You can expand the rail so that its
mounting brackets are spaced between 24 to 32 inches (60.96 to 81.28 cm).
• 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. Statement 1006
