MX2000 DC Power Distribution Module (240 V China) Description

 

In the DC power configuration, the router contains up to two DC power distribution modules (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 DC PDM provides a 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 DC PDMs) are supported.

Note

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

Each DC PDM (240 V China) has nine DC inputs, (see Figure 1).
