Install the Chassis
Step 1 Install two rack-mount brackets to the router as follows:
a) Determine which end of the chassis is to be located in the cold aisle as follows:
• If the router has port-side intake modules (fan modules with burgundy coloring), position the router so that the
ports are in the cold aisle.
• If the router has port-side exhaust modules (fan modules with blue coloring), position the router so that the fan
and power supply modules are in the cold aisle.
b) Position a rack-mount bracket on the side of the chassis with its four holes aligned to four of the screw holes on the
side of the chassis, and then use four M4 flat-head screws to attach the bracket to the chassis.
Note Cisco NCS 55A1-36H-S, NCS 5502, NCS 5502 SE: Remove the grounding cover label and align the
grounding cover plate with the grounding holes in the chassis and attach the rack mount brackets.
Note You can align four of the holes in the rack-mount bracket to four of the screw holes on the front side of
chassis or four of the screw holes on the rear side of the chassis. The holes that you use depend on which
side your chassis need to be put in the cold aisle.
