Step2 Attach the left and right hinge brackets to the chassis using three screws (M4 thread) for each bracket.
Tighten the screws to a torque of 11in-lb (1.20 N-m). The L-shaped brackets should align with the holes
in the cable management tray from which you removed the screws.
Step3 Secure the L-shaped brackets to the chassis and cable management tray by re-inserting and tightening
the cable management tray screws you removed.
Step4 Align the exhaust air deflector at the rear of the chassis behind the top fan tray outlets (Figure2-84), and
use a screwdriver to tighten the two screws, one on each side of the deflector. The deflector’s
measurements are width 17.48” x height 4.72” x depth 5.21” and deflects the outgoing exhaust air.
