A rack system includes a rack base defining a plurality of device slots. A rack wall on the rack base defines a rack volume adjacent a first device slot. A rack volume device coupling system is located in the rack volume and includes a rack volume base positioned in the rack volume. A rack tray is moveably coupled to the rack volume base and configured to move from a first orientation where the rack tray is located in the rack tray housing, to a second orientation where the rack tray extends from the rack volume and into the first device slot. A device is then moved through the first device slot and into the rack tray when the rack tray is in the second orientation. The rack tray is then moved from the second orientation and into the first orientation such that the device is located in the rack volume.
