If the bottom-support rails are extended a long distance, they can bend outwards slightly when you install the
chassis and the chassis stops at the far end of the rails might not fit into the end of the chassis. If this happens,
press the side rails toward the sides of the chassis so that the chassis stops can go inside the chassis and hold
it in place on the rack. Note
Receiving hole on each side of the chassis for the
chassis stops on the bottom-support rails. 3 Slide the power-supply end of the chassis onto the
bottom-support rails so that the chassis locks onto the
chassis stops at the end of the rails. 1
Customer-supplied rack-mount screw (M6 x 10 mm
screw or other screw appropriate for the rack) used to
secure each side of the chassis to the rack. 4 Chassis stops for holding the chassis (positioned by
the aisle required for the fan and power supply
modules). 2
Step 2
Use a customer-supplied rack-mount screw (an M6 x 10 mm screw or other appropriate screw for the rack) to attach each
of the two mounting brackets on the chassis to the rack and tighten each screw to the appropriate torque setting for the
screw (for M6 x 10 mm screws, use 40 in-lbs [4.5 N·m] of torque).
