Step 2
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 11 in-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.
Step 3
Secure the L-shaped brackets to the chassis and cable management tray by re-inserting and tightening the
cable management tray screws you removed.
Step 4
Align the exhaust air deflector at the rear of the chassis behind the top fan tray outlets (see the below figure),
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.
