Figure 23. Unpacking the Model 106 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 Module
removal and replacement. Disk drive modules are installed separately after the enclosure is
mounted in the rack.
Upon completion of this step, go to Step 3.
b. Alternative method: Remove the enclosure from its box using the optional lift handles.
See Figure 24 on page 31 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 Appendix C, “Enclosure packaging,” on page 91 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.
