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.

After the chassis has been installed in the rack and all chassis accessories have been attached, you can install
the fan trays, power supply modules, RP cards, FCs and LCs. See Installing Cards and Modules in the Chassis
in the book Cisco ASR 9000 Series Aggregation Services Router Hardware Installation Guide for detailed
installation instructions.
