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

(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.
