At least one dedicated staging area should be part of the data center design. Staging is an area between the loading dock and the equipment's final destination, and is often used for equipment configuration. Equipment coming from receiving on its way to the data center, as well as equipment moving from the data center out to storage or shipping, will usually be processed in the staging area.
This area should be outside the data center, but should be maintained within similar parameters. Contamination will be generated by packing, unpacking, and component handling and this must be isolated from the operational equipment. The staging area also involves a lot more human and machine traffic that can add to and stir up contaminants.
