b.
In preparation to perform a team lift, position one individual on each side of the enclosure
(to lift) and a third individual standing at the protruding rack rails (to guide the chassis to
mate with rack rails).

Caution: This step in the installation requires a minimum of 3 individuals to
install safely, two to lift and one to guide the others who may have difficulty
seeing because the enclosure is in the way. Ensure that the appropriate
measures are taken to safely support the enclosure during installation. The
enclosure MUST have no drives installed and requires a two person team
lift to install. Do not attempt to lift the system if it is fully populated with
drives. The only case in which the system may be installed or removed
with the drives populated is if the facility has a lift that is rated to handle the
maximum weight of the fully loaded system.
Warning: The handles on the front of the chassis are not intended
to be used to support the weight of the Ultrastar Data60. Lifting the unit by
the chassis handles or trying to support the unit on the handles can cause
them to fail. This can cause serious damage to the unit or serious bodily
harm to those handling the unit. Always team lift the chassis by gripping the
underside of the unit, and never try to lift a chassis that is filled with drives.
Warning: Do not lift the chassis by the Cable Tray while removing the
chassis from the rack OR while installing it into a rack. This can cause serious
damage to the unit or serious bodily harm to those handling the unit. Always
team lift the chassis by gripping the underside of the unit, and never try to lift
a chassis that is filled with drives.
