MX2020 Power Midplane Description


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.
