    Mapping Input Power from Three-Phase Wye AC Power Distribution Modules to AC Power Supply Modules on the MX2020 Router

    You connect AC power to the router with three-phase wye AC PDMs by connecting two AC power cords in such a way that input #1 cord is capable of supplying power to six PSMs and input #2 is capable of supplying power to three PSMs (this is to match the internals of the PDM where one feed gets mapped to six PSMs and the other gets mapped to three PSMs), (see Figure 1). Table 1 shows the three-phase wye AC PDM input mapping to AC PDM0 and PDM1. Table 2 shows the three-phase wye AC PDM input mapping to AC PDM2 and PDM3.
