Mounting a chassis in a rack
Follow these steps to mount a PowerConnect B-MLXe Series chassis in a rack.
NOTE
You must provide standard #12-24 pan-head screws to mount each chassis in a rack. You will need a Phillips
screwdriver to perform this task.
1. Determine the position of each chassis in the rack. For example, place units with the fewest modules near the
top of the rack, units with more modules near the middle of the rack, and fully populated units near the bottom
of the rack.
2. Using the keyhole slots in the chassis mounting brackets as a guide, align one screw per rack post, as shown in
Figure 5 on page 13. On one side of the rack, the screw should align with the top hole in the mounting bracket.
On the other side of the rack, the screw should align with the bottom hole of the mounting bracket. When
tightening these screws, leave approximately 1/4-inch of clearance between the back of the screw head and the
rack post.

3. Starting with the chassis that will be in the lowest position in the rack, mount the chassis in the rack as shown in
the example of the 8-slot chassis in
Figure 6 . With two or more people lifting the chassis, slip the wide portion of
each keyhole slot over the corresponding mounting screw in the rack post.
