Install the Chassis

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 its

ports will be in the cold aisle.

• If the router has port-side exhaust modules (fan modules with blue coloring), position the router so that its fan

and power supply modules will be in the cold aisle.

b) With the bracket ears facing toward the center of the chassis, position a front rack-mount bracket on the side of the

chassis so that the four holes are aligned to four of the screw holes on the side of the chassis.

c) Use four M4 screws to attach the bracket to the chassis

d) Repeat Steps 1b and 1c with the other rack-mount bracket on the other side of the router.

Note

The following image shows the rack-mount brackets on the Cisco NCS 5501. The bracket installation is the

same for the Cisco NCS 5501-SE and Cisco NCS 55A1-24H.

Step 2

Install the router onto the 2-post rack as follows:

a) With two people, lift the router into position between the two rack posts.

b) Move the router until the rack-mount brackets come in contact with two rack posts.

c) Hold the chassis level while the second person inserts two screws (12-24 or 10-32, depending on the rack type) in

each of the two rack-mount brackets (using a total of four screws) and into the cage nuts or threaded holes in the

vertical rack-mounting rails.

d) Tighten the 10-32 screws to 20 in-lb (2.26 N.m) or tighten the 12-24 screws to 30 in-lb (3.39 N.m).
