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 44: MX2000 DC PDM (240 V China)
Figure 44 on page 113).
