MX2020 Power Midplane Description on page 20
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.

MX2020 Backplane Description on page 19
The current MX2020 router requires an adapter card (ADC) to house the MPCs. The
MPCs attach to the ADCs which in turn attach to the backplane. Future MPCs for the
MX2020 can be used without an ADC.
The MX2020 router has 20 dedicated line card slots, which means a maximum of 20
ADCs can be installed. The dedicated slots are numbered
though (top), left to right. ADCs install vertically in the front of the router.

When a slot is not occupied by a combined ADC and MPC, the user must insert a blank
panel to fill the empty slot and ensure proper cooling of the system.
ADCs are hot-removable and hot-insertable.
