Table 67: Calculating AC Thermal Output
Thermal Output (BTUs per hour)Power Distribution Module
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 167
to calculate maximum power, which is dependent on
configuration and temperature.
MX2020 Three-phase delta AC PDM
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 167
to calculate maximum power, which is dependent on
configuration and temperature.

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 72 on page 191 shows the mapping for the MX2010
and Figure 73 on page 191 shows the mapping for the MX2020. The arrangement matches the internal
components of the PDM. Table 68 on page 192 shows the AC PDM input mapping to AC PDM0/Input0
and PDM1/Input1 (MX2010 and MX2020). Table 69 on page 192 shows the AC PDM input mapping to
AC PDM2/Input0 and PDM3/Input1 (MX2020 only).
