MX2020 Power Midplane Description

Copyright © 2015, Juniper Networks, Inc.
NOTE: The MX2020 systems configured for DC input power must use only
DC PDMs and DC PSMs. Systems configured for three-phase wye AC input
power must use only three-phase wye AC PDMs and AC PSMs. Systems
configured for three-phase delta AC input power must use only three-phase
delta AC PDMs and AC PSMs. AC and DC PSMs or PDMs must not be mixed
within a single system.

The MX2020 power subsystem consists of a power midplane (PMP). This midplane is
used to connect power from the PDM feeds (AC or DC) to the input of the PSMs (AC or
DC) as well as the output from the PSMs to the FRUs (MPCs, CB-REs, SFBs, and Fan
Trays). The power midplane plugs into the signal backplane. The PSMs and PDMs get
plugged into the power midplane.
