Step 4 Attach the rear rack-mounting brackets (part number: 700-47414-01) to the left and right sides of the plenum
base, using twelve 8-32 x 0.5 in. pan-head screws ((part number: 48-0828-01), six per bracket.
• If you are installing the chassis in a two-post rack, the rear rack-mounting brackets secure the plenum
to the rear of the rack-posts (Figure 150: Installing the Plenum in a Two-Post 19-Inch Rack, on page
142).
• If you are installing the chassis in a four-post rack, rotate the rear rack-mounting brackets by 180 degrees
and attach to both sides of the plenum. The rear rack-mounting brackets secure the plenum to the rear
rack-posts.
Step 5 Insert and tighten four customer-supplied screws to secure the plenum to the rear of the rack-post (two on
each side). These screws can vary in size and type depending on the rack that you use. Torque the screws to
the weight specified for your particular rack (see the figure below).
