MX2000 DC Power Distribution Module (240 V China) Description

 

In the DC (240-V China) power configuration, the MX2000 router contains up to four DC PDMs (240-V China) located at the rear of the chassis in slots PDM0/Input0 through PDM3/Input1 (bottom to top). A minimum of one PDM is required per subsystem (two PDMs per MX2020 chassis) for nonredundant power. The DC PDMs provide power interface to nine power supply modules (PSMs).

Four PDMs provide full redundancy for the MX2020 router. In a redundant configuration, a total of thirty-six (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).
