You connect AC power to the router with AC PDMs by connecting two AC power cords
to each PDM. One feed maps to six PSMs and the other maps to three PSMs (see
Figure 74 on page 169). The arrangement matches the internal components of the PDM.
Table 64 on page 169 shows the AC PDM input mapping to AC
PDM1/Input1 . Table 65 on page 170
and .
PDM3/Input1
Thermal Output (BTUs per hour)
Maximum power divided by 0.91 * 3.41 = BTU/hr.
Input power = Maximum power divided by 0.91
Refer to "MX2020 AC Power Requirements" on
page 147 to calculate maximum power, which is
dependent on configuration and temperature.
