5. 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).
DETAILED STEPS
Step 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).
Be sure to align four of the screw holes on the larger side of the bracket with the four screw holes near the center of the
left or right side of the chassis.

chassis and the longer side facing the front (port side)
of the chassis. Align four screw holes in the bracket
to four screw holes in the side of the chassis. 1
Step 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).
Step 3 Repeat Steps 1 and 2 to attach the second center-mount bracket to the other side of the chassis.
Step 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.
If these modules have a blue coloring for port-side exhaust airflow, then you must position the modules by the cold aisle.
If the modules have a burgundy coloring for port-side intake airflow, you must position the modules by the hot aisle.
