Power Supply Socket
The Power supply sockets (Figure 18, A) distribute the power for each column of modules in
the LED Wall. The sockets are male and female adapters at the top and bottom surfaces of the
cabinet. The sockets interconnect two cabinets of a column (Figure 19). The socket is
connected to the Power distribution unit (PDU) (wiring, C).
The sockets wire to the PDU (Figure 20, D) and ground (E) on the cabinet. The PDU, in turn,
connects to the Power supply unit (F) via the hub board's power supply connector (see also
Figure 26, D, p. 28).
