An RFID tag assembly for attachment to an enclosure surface including a door, an RFID tag attached to one face of the door or wrapped around the door, and an attachment device for connecting the door to the enclosure surface to allow the door to move to a position that shows both sides of the door. The RFID tag can include a ground plane, the tag wrapped around the door such that the ground plane is on the back of the door and the RFID tag antenna is on the front of the door. A ground plane can be provided on the enclosure inner or outer surface in alignment with the RFID tag antenna, with the antenna directly or inductively coupled to the ground plane when the door is in a closed position.

An electronic device cabinet includes a first temperature control system positioned to direct a conditioned airflow into a first electronic device storage zone of the cabinet and a second temperature control system positioned to direct a conditioned airflow into a second electronic device storage zone of the cabinet. The first temperature control system includes a first plurality of vortex tubes having a compressed air inlet and a first cooling air outlet that guides cooling air into the first device storage zone. The second temperature control system includes a second plurality of vortex tubes having a compressed air inlet and a second cooling air outlet that guides cooling air into the second device storage zone. A controller selectively delivers compressed air to respective ones of the first and second temperature control systems upon sensing a demand for cooling in corresponding ones of the first and second electronic device storage zones.
