5. Repacking a Rack for Shipment
Repacking the Rack in the Enterprise Packaging
Refer to the unpacking instructions included with the packaging when unpacking the rack from the shipping carton. After unpacking the rack, follow local laws and guidelines to recycle the packaging properly.
![]() | Caution - Carefully unpack the rack from the packaging and shipping pallet. Rocking or tilting the rack can cause it to fall over and cause serious injury or death. We strongly suggest that you always use professional movers when unpacking and installing this rack. |
Note - After unpacking the rack from the packaging, save the mounting brackets used to secure the rack to the shipping pallet. You can use these mounting brackets to secure the rack permanently to the installation site floor. Do not dispose of these brackets, as you will not be able to order replacement brackets.
The Sun Rack II can ship in two different packaging options: the standard packaging and the enterprise packaging. The standard packaging is suitable only for shipping empty racks. The heavy-duty enterprise packaging is suitable for shipping racks with factory-installed or customer loaded equipment.
Figure 2-1 Standard and Enterprise Packaging

![]() | Caution - The standard packaging was designed solely for shipping an empty rack. Never install equipment in the rack while it is on this pallet, and never repack a rack in the standard packaging. If you must populate the rack prior to moving it to a new building or site, repack the rack in the enterprise packaging. |
Contact your sales representative for information about ordering empty enterprise packaging. For instructions on how to repack a rack in the enterprise packaging, see Repacking the Rack in the Enterprise Packaging.
