MX2010 High-Voltage Universal (HVAC/HVDC) Power Distribution Module Description


The MX2008, MX2010, and MX2020 routers support the same power modules AC, DC, 240 V China, and universal PSMs and PDMs.

In the high-voltage second-generation universal (HVAC/HVDC) power configuration, the MX2000 router contains two high-voltage universal (MX2K-PDM-HV) 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 chassis) for nonredundant power. The universal (HVAC/HVDC) PDMs provide power interface to nine power supply modules (PSMs).

Two PDMs provide full redundancy for the router. In a redundant configuration, a total of a total of eighteen (9-feed PDMs) are supported.


The power backplane for a subsystem distributes regulated 52 VDC to all boards supplied by that subsystem.

Each high-voltage universal (HVAC/HVDC) PDM has nine (HVAC/HVDC) inputs, (see Figure 1).
