Figure 22. Unpacking the Disk Enclosure using straps
CAUTION: With three persons - positioned one at each corner rear corner, and one at the
front of the enclosure - grip the straps securely by the loops, and lift the enclosure out of the
box using appropriate lifting technique. Place the enclosure in a static-protected area.
Except for the disk drive modules, enclosures are supplied with all integrated PCBs and all
plug-in modules installed. For information about plug-in module replacement, see the section
Chapter 7, “Module removal and installation,” on page 55. Disk drive modules are installed
separately after the enclosure is mounted in the rack.
• Alternative method: remove the enclosure from its box using the optional lift handles.
See the figure below and the CAUTION above and below the illustration. Only the straps and plastic
bag are shown. They are isolated from the remainder of the packaging. As a visual aid for this
unpacking task, see Chapter 9, “Enclosure packaging,” on page 75 for more information about the
packaging materials. The illustration shows two steel lift handles installed on the left side of the
chassis just below the enclosure lid. Two additional steel lift handles are symmetrically attached on
the right side of the enclosure (hidden in this view).
CAUTION: Verify that each of the four lift handles is securely fastened to the enclosure sheet
metal before performing the lift. Optional lift handles are attached to the enclosure side wall
using the spring-loaded push-pull attachment pin located on the attachment flange of each
lift handle. These handles are designed to support the weight of a partially populated
enclosure: chassis and CRUs only (as shipped). The handles are not designed to hold the
weight of a fully populated enclosure that also includes the disk drives.
