Installing A Chassis In A Rack Or Cabinet - Cisco Nexus 7718 Hardware Installation Manual

Installing a Chassis in a Rack or Cabinet

Step 2 Attach the bottom-support rail to the rack or cabinet. Use a Phillips screwdriver to screw in four M6 x 19 mm
or 12-24 x 3/4 inch Phillips screws on each end of the rail (using a total of 8 screws for the rail) as shown in
the following figure. Tighten each screw to 40 in. lbs (4.5 N.m) of torque.

Step 3
Repeat the first two steps to attach the other bottom-support rail to the other side of the rack.
Note
What to Do Next
When the bottom-support rails are installed at the lowest possible RU and are level, you are ready to install
the chassis in the rack or cabinet.
Installing a Chassis in a Rack or Cabinet
To move a chassis to a rack, it is necessary to slide the chassis onto a mechanical lift, use that mechanical lift
to position the chassis in front of its place on the rack, slide the chassis from the lift to the rack, and then bolt
the chassis to the rack. You can make the chassis easier to move if you remove the power supplies, fan trays,
and fabric modules. These modules are sealed to minimize the chance of being damaged by electrostatic
discharge (ESD), so you can remove them from the chassis to make the chassis easier to move.

Make sure that the two bottom-support rails are level with one another. If they are not level, adjust
the higher rail down to the level of the lower rail.
