Step 1 If you need to make the chassis as light as possible for moving, remove the following modules and place them where
their connectors will not be damaged:
• Power supplies—For each power supply, press and hold the eject lever, and use the handle on the front of the power
supply to pull the power supply out of the chassis.
• Fan trays—Unscrew the four captive screws, and use the two handles on the fan tray to pull the fan tray out of the
chassis.
• Fabric modules—For each fabric module, keep your face at least 12 inches (30 cm) away from the modules, press
both eject buttons on the front, rotate both levers away from the front of the module, use the levers to pull the
module out of the chassis.
Step 2 Load the chassis onto a mechanical lift as follows:
a) Position the mechanical lift next to the shipping pallet that holds the chassis.
b) Elevate the lift platform to the level of the bottom of the chassis (or no more than 1/4 inch [0.635 cm] below the
bottom of the chassis).
c) Use at least two persons to slide the chassis fully onto the lift so that the side of the chassis touches or is close to the
vertical rails on the lift. Make sure that the front and rear of the chassis are unobstructed so you can easily push the
chassis into the rack.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles
Warning
on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the
weight of the unit.
To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis (the handles are not
Note
rated for lifting over 200 pounds [91 kg]). Use the side handles for only repositioning the chassis after it is
already on the mechanical lift or in the rack or cabinet.
Step 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.
Step 4
Push the chassis halfway onto the rack or cabinet.
Use at least two persons to push the chassis onto the bottom-support rails and one person to guide the chassis down the
center of the rails. Push the lower half of the front side of the chassis so that the back side enters the rack first, and push

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
When mounting this unit in a partially filled rack, load the rack from the bottom to the top with
the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing
the unit in the rack.
