Installing a 2 (RU) Chassis in a Two-Post Rack
This section describes the rack installation for the Cisco Nexus 3000 series switch into a two-post rack.
You need to attach a right-angled bracket to each side of the chassis. This bracket centers the chassis and
secures it in place on a two-post rack.
Position the chassis near the top of the rack with the power supply and fan modules in the appropriate aisle
for their required airflow. If the fan modules have a blue coloring for port-side exhaust airflow, then you must
position the modules by the cold aisle. If the fan modules have a burgundy coloring for port-side intake airflow,
you must position the modules by the hot aisle.
Statement 1006— Chassis Warning for Rack-Mounting and Servicing
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.
Warning
Before you begin
• You must separately order the center-mount brackets if you are installing the chassis in a two-post rack.
These brackets do not ship with the chassis unless you specifically order them.
• You must have the following tools and equipment:
• Manual Phillips-head torque screwdriver
• Center-mount bracket kit
• Make sure that you have six customer-supplied rack-mount screws (typically M6 x 10 mm or the
appropriate screw for the vertical mounting rails on the rack).
• You have at least two people to install the chassis.
SUMMARY STEPS
1. Align one of the two center-mount brackets on the left or right side of the chassis and be sure that the
angled portion is facing the front of the chassis (see the following figure).
2. Use four M4 x 8 mm screws to attach the bracket to the chassis. Tighten each screw to 11 to 15 in-lb (1.2
to 1.7 N·m).
3.
Repeat Steps 1 and 2 to attach the second center-mount bracket to the other side of the chassis.
4. Use one person to position the chassis so that it is near the top of the rack with the fan and power supply
modules in the appropriate aisle and the center-mount bracket has its screw holes aligned to screw holes
on the two-post rack.
