Each FTX cabinet has one power supply box. The IP66 rated power supply box is where the electrical components that power and control the tiles are located including the power supplies, thunderbolt and hub cards. It is also where all connections are made inside the cabinet. There is one Thunderbolt card in each power supply box that controls the tiles for the cabinet. It also receives and transmits the video signal to neighboring cabinets via the two Ethernet ports on the bottom of the card. The hub card, where the tile harnesses connect, is mounted onto the top of the Thunderbolt card.
