Step4 Attach the left and right air baffles to the plenum base using the Cisco supplied M5x10mm screws (four
for each air baffle). The keyholes on each side of the plenum base will help to guide the air baffles into
position (Figure 2-11).
Step5 Position the air filter at the front of the plenum assembly using the two key locators. Insert and
hand-tighten the two captive screws to secure the air filter assembly to the plenum assembly
(Figure 2-12).
Step6 Position the cable management tray at the front of the plenum assembly (Figure2-13). Insert and
hand-tighten both captive screws to secure the cable management tray to the plenum assembly.
Step7 If you are installing the air plenum kit to a four-post rack:
a. Attach the rear adapter plates to the rear side of the plenum assembly.
b. Fasten the rear adapter plates with M3 x 10mm screws, three on each side (Figure2-8).
