Power Distribution

Figure 15: Power supply label

According to the power supply label, this unit has two +12 V rails. However, this information is incorrect. Inside the unit, all yellow (+12 V) wires are connected to the same point, and the power supply doesn’t implement over current protection (OCP), which is required to create individual +12 V virtual rails.
