Mapping Input Power from AC Power Distribution Modules to AC Power Supply Modules on MX2000 Routers

 

You connect AC power to the router by connecting two AC power cords to each AC PDM. One feed maps to six PSMs and the other maps to three PSMs. Figure 1 shows the mapping for the MX2010 and Figure 2 shows the mapping for the MX2020. The arrangement matches the internal components of the PDM. Table 1 shows the AC PDM input mapping to AC PDM0/Input0 and PDM1/Input1 (MX2010 and MX2020). Table 2 shows the AC PDM input mapping to AC PDM2/Input0 and PDM3/Input1 (MX2020 only).

Best Practice

To achieve complete redundancy when you have two power sources, such as Source A and Source B, we recommend that you connect them as follows:

  • Connect Source A to PDM0-left and PDM0-right

  • Connect Source B to PDM1-left and PDM1-right
