Abstract: A cargo rack is usable to store electronic devices, such as servers, while the electronic devices operate. The cargo rack has a telescoping enclosure with one or two doors for selectively closing either or both ends of the enclosure. The cargo rack also includes an onboard electronic system. The electronic system includes a programmable controller and an access control system for selectively locking or unlocking the door or doors of the enclosure. The access control system includes a security interface at which access credentials may be presented from outside the enclosure for recognition by electronics within the enclosure.
