This is a requirement for proper cooling. When installing the array in the cabinet, install the enclosures from the bottom up (to prevent the cabinet from becoming top heavy and avoid a potential tipping hazard). Refer to the document supplied with the rack for proper installation information. Typically, disk enclosures are installed from the bottom of the rack up, with the controller enclosure installed directly above the disk enclosures.
