MX2020 AC Power Requirements
To allow for future growth so that you can operate the router in any hardware configuration without
upgrading the power infrastructure, we recommend that you provision 2800 W for each AC power
distribution module (PDM) (three-phase or single-phase).
If you do not plan to provision 2800 W for each AC power supply module (PSM), use the information in
Table 55 on page 168 and
configurations, input current from a different source voltage, and thermal output.
Table 57 on page 169 lists the power requirements for various hardware components when the router is
operating under typical voltage conditions.
NOTE: Unlike all the other MPCs, MPC6E, MPC8E, and MPC9E do not require an adapter card
(ADC) to house the MPC in the MX2020 router.
