Mounting brackets for 19-inch, 600-mm, and 23-inch racks are supplied.
2. Get into chassis lifting position.

If using a mechanical lift aid, at least two people are required. The chassis should
be center balanced.

Three people: Two in the front, and one positioned center chassis back.
•
Four people: Two in the front and two in the back, each positioned at a corner of
the chassis.
3. With the chassis front facing, grasp the chassis from the bottom, with all personnel
positioning their hands on the chassis in the positions stated in Step 1, to ensure proper
chassis balance.
4. At the same time, each person slowly lift the chassis and slide it onto the rack until
the chassis mounting brackets meet the rack posts.
5. Align the chassis mounting bracket holes with the rack post holes.
6. Insert each screw, loosely, through the lock washer then the flat washer, through the
bracket, and finally into the rack post holeone screw in the top bracket hole on each
side, and one screw in the bottom bracket hole on each side. When all the screws are
in place, tighten the screws into the rack post.
7. Verify that the chassis is properly placed in the rack, and check each screw to ensure
it is securely tightened.
