Chapter 2 Installing a Cisco Nexus 7004 Chassis
To move the chassis, either use the chassis handles (one found on each side) or push on the sides or edges
Caution
of the chassis without touching any of the modules or module handles.
To move the chassis with a mechanical lift, position the lift at the elevation of the chassis on its
•
shipping pallet (or no more than 0.25 inches [0.64 cm] below the level of the pallet) and use two
persons to push the chassis fully onto the lift.
To move the chassis manually, remove the power supplies as explained in one of the following
•
sections and then use two persons to lift the chassis:
–
–
Note
Lift the chassis to its position on a rack in one of the following ways:
Step 2
If you use a mechanical lift, position the chassis next to the front of another Cisco Nexus 7004
•
chassis already installed in the rack, elevate the new chassis to the level of the installed chassis (or
no more than 0.25 inches [0.64 cm] above the installed chassis, use two persons to align the back
side of the new chassis to the opening between the two front posts of the rack and push the chassis
into the installed chassis until the chassis mounting brackets come in contact with the rack mounting
rails.
If you are lifting the chassis manually, use two or more persons to move the back end of the chassis
•
through the front posts until the chassis mounting brackets come in contact with the mounting rails
on the rack, lift the chassis to the lowest possible RU for it on the rack, and align the screw holes in
the chassis mounting brackets to the rack mounting rails.
Caution Use two persons to lift the chassis by using the handle on each side of the chassis. Do not use the handles
on any of the modules installed on the chassis to lift or move the chassis—these handles are for only
removing or installing the modules.
Use five M6 x 19 mm screws (or 12-24 x 3/4 inch screws) to fasten each side of the chassis to the rack.
Step 3
Tighten each of the 10 screws to 40 in. lbs (4.5 N.m) (see

To remove a DC power supply, see the
Operations" section on page
We do not recommend that you remove any of the supervisor modules, I/O modules, or the fan
tray to make the chassis easier to lift because that removal can put those modules at risk of being
damaged. If you do remove any of those modules, be sure to have antistatic pads or antistatic
bags to hold these modules until you are ready to reinstall them in the chassis.
