A method includes: reading, by a tile lifter, a radio-frequency identification (RFID) tag within a floor tile that is locked to a support structure; comparing, by the tile lifter, a personal identification number (PIN) of the RFID tag to an access code within the tile lifter; determining, by the tile lifter, a match between the PIN of the RFID tag and the access code; and actuating, by the tile lifter and in response to the determining the match, an actuator in the floor tile.

A standard server rack is modified to be able to detect if a blanking panel is missing from an unoccupied slot. Detection can be achieved electrically by providing switch elements in the holes on the rack siderails, whose switching state depends on whether a fastening pin is in the hole. A blanking panel, when fitted to a particular slot, thus switches the switch elements for that slot, which can be detected by a make/break circuit including the switch elements. Alternatively, detection of a missing blanking panel can be achieved optically by arranging a bank of forward pointing optical sensors at the back of the server rack, which point forward to detect the presence of a blanking panel. The optical sensors are distributed vertically so that at least one optical sensor covers each slot.

Concepts for determining a structural integrity of a raised floor comprising an array of stringers and stanchions are presented. Each stringer is supported at opposite ends by a respective pair of stanchions. One example comprises a system having a transmitter configured to transmit a signal between a pair of stanchions via a respective stringer and a receiver configured to receive the transmitted signal. The system further comprises a processing unit configured to determine a status of the stringer based on the received signal, then determine an indicator of a structural integrity of a raised floor based on the determined status.
