Installing the Chassis
Step 3
Use two customer-supplied screws (typically M6 x 10 mm screws) to attach the bottom-support rail half to the vertical
mounting rails on the rack post. 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).
Step 4
Slide the other half of the bottom-support rail onto the attached half of the rail set and use two customer supplied screws
(typically M6 x 10 mm screws) to secure that portion to the vertical mounting rails on 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).

Step 5 Repeat Steps 2 and 3 to attach the other expanding bottom-support rails to the other side of the rack.
Check the two installed bottom support rails to be sure that both have their chassis stops by the same aisle
Note
(either both by the hot aisle or both by the cold aisle) and that both rails are level and level with each other. If
they are not level, adjust the higher rail down to the level of the lower rail.
