Installing the Chassis
1
Three customer-supplied screws (typically M6 x 10
mm screws or the appropriate screws for the rack) to
hold each side of the chassis to the two-post rack.
Step 2
Use the second person to secure the three customer-supplied rack-mount screws (typically M6 x 10 mm or other appropriate
screws for the rack) on each center-mount bracket to attach the chassis to the rack. Tighten each screw to the appropriate
torque setting for the screws (for M6 x 10 mm screws, use 40 in-lbs [4.5 N·m] of torque).

Before you install the chassis, be sure that the rack is fully secured to the data center floor.

Attaching the Bottom-Support Rails to the Rack
The switch chassis that you are installing ships with two adjustable bottom-support rails that you can attach
to a four-post rack to hold the chassis. Each of these bottom-support rails has two pieces—one that slides into
the other so that you can adjust them to fit racks with front and rear mounting posts that are spaced less than
36 inches (91 cm). On each bottom-support rail, the rail half that slides into the other rail includes a chassis
stop that fits into the module end of the chassis. Depending on direction of the chassis airflow, you need to
position the rail half with the chassis stop so that the fan and power supply modules end up in the appropriate
aisle as follows:
• Port-side intake (burgundy coloring for fan modules) airflow requires that the bottom-support rail with
the chassis stop be located on the hot aisle side of the rack.
