Installing the Chassis

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).

Installing the Chassis in a Four-Post Rack

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

You must attach the bottom support rails to the rack and attach the mounting brackets to the chassis before

mounting the chassis in 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:
