To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions
to ensure that the system remains stable. The following guidelines are provided to ensure your safety:
Warning
•
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.
Statement 1006
Procedure
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 four 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 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
Warning
To lift the chassis, use a mechanical lift, not the handles on the side of the chassis (the handles are
not 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.
