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).
c. Team-lift the enclosure until the inner rails (which are attached to the chassis) align with the
extended mid-rails (which are attached to the rack), and guide the inner rails on the chassis
to mate with the 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 Data102 . 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.
