people. To lighten the chassis for lifting, you can remove the power supplies so that the chassis weighs no
more than 93 pounds (42 kg) and can be lifted by two people.
After lifting the chassis into position, you fasten it to the rack, and replace any power supplies that you might
have removed earlier.
To install a Cisco Nexus 7004 chassis in a two- or four-post rack or cabinet, follow these steps:
SUMMARY STEPS
1.
Prepare the chassis for moving by doing one of the following:
2.
Lift the chassis to its position on a rack in one of the following ways:
3.
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.
Tighten each of the 10 screws to 40 in. lbs (4.5 N.m) (see
Figure 2: Mounting the Cisco Nexus 7004
4.
If you removed any power supplies, replace them as explained in one of the following sections:
DETAILED STEPS
Step 1
Prepare the chassis for moving by doing one of the following:
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles
on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the
weight of the unit. Statement 1032
Danger
To move the chassis, either use the chassis handles (one found on each side) or push on the sides or edges of
the chassis without touching any of the modules or module handles.
Caution
• 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:
• To remove an AC power supply, see the
“Removing a 3-kW AC Power Supply Unit During Operations” section
• To remove a DC power supply, see the
“Removing a 3-kW DC Power Supply Unit During Operations” section
• To remove an HVAC/HVDC power supply, see the
“Removing a 3.5-kW HVAC/HVDC Power Supply Unit
During Operations” section on page 10-16
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.
Note
Step 2
Lift the chassis to its position on a rack in one of the following ways:
• 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
