    MX2010 Seven-Feed DC Power Distribution Module Description

    In the DC power configuration, the router contains up to two DC PDMs located at the rear of the chassis in slots PDM0/Input0 and PDM1/Input1 (bottom to top). A minimum of one PDM is required per system (two PDMs per MX2010 chassis) for nonredundant power. The DC PDMs provides power interface to nine PSMs.

    Four PDMs provide full redundancy.

    Note: Power backplane distributes regulated 52 VDC to all boards supplied by that system.

    Each DC PDM has seven DC inputs (–48 VDC and return terminals for each input) (see Figure 1). Select 60 A or 80 A input feed capacity on the DC PDM by setting the switch to the rated amperage of DC power input feeds.

    Note: This switch applies to all inputs of this PDM. Selecting 60 A reduces the available power output capacity of the PSMs supplied by this PDM.

    DC Power Distribution

    Note: The type of feed that you use on the DC PDM (60 A or 80 A) depends on the distribution scheme and distribution equipment. With a 60-A feed, the maximum power supply output power is limited to 2100 W while the maximum power supply input power is limited to 2400 W. With an 80-A feed, the maximum power supply output is limited to 2500 W while maximum power supply input power is limited to 2800 W. The system power management software calculates the available and used power based on DIP switch positions in the PDM.
