Installing the Chassis

To install a Cisco Nexus 7018 chassis in a four-post rack or cabinet, follow these steps:
SUMMARY STEPS
1. To lighten the chassis, we recommend that you remove the fan trays from the chassis. The electronics on
these modules are well sealed from damage but you must still be careful not to damage their connectors.
To remove a fan tray, follow these steps:
2. Load the chassis onto a mechanical lift as follows:
3. Use the mechanical lift to move and align the rear of the chassis to the front of the four-post rack or
cabinet. Make sure that the bottom of the chassis is elevated to the height of the bottom-support rails or
no more than 1/4 inch (0.6 cm) above the bracket.
4. Use at least two persons to push the chassis half way onto the installed bottom-support rails as shown in
Figure 50: Moving a Cisco Nexus 7018 Chassis onto a Rack, on page 103
back of the chassis so that it does not get caught on anything as it is pushed into the rack.
5. Lower the lift until it is no more than 0.25 inches below the bottom support rails. This action ensures that
the chassis is not pointing downwards in a way that might get it caught on the expansion edge of the
bottom support rails.
6. With the chassis flat on the bottom support rails, use two persons to push evenly on each side of the chassis
until it is fully loaded onto the rack (the two mounting brackets on the front of the chassis come into
contact with the two vertical mounting rails on the front of the rack). Use a third person to guide the
chassis so that the rear of the chassis (the side being pushed into the rack) does not get caught on any
edges of the bottom support rails.
7. Make sure that the screw holes in the chassis mounting brackets align with the screw holes in the vertical
mounting rails.
8. Use a Phillips torque screwdriver to screw in nine M6 x 19-mm or 12-24 x 3/4-inch screws in each of the
two chassis mounting brackets (use a total of 18 screws for two mounting brackets) as shown in
51: Attaching the Cisco Nexus 7018 Chassis to the Rack, on page
of 40 in-lb [4.5 N·m] of torque.
You should also have at least two persons to push the chassis, which can weigh up to 700 pounds (318 kg)
or, if you remove all fan trays and power supplies, it can weigh up to 500 pounds (227 kg), onto and off the
mechanical lift and rack. We also recommend that you use a third person for guiding the chassis as it is being
pushed.
