The MX2020 3D Universal Edge Router is an Ethernet-optimized edge router that provides
both switching and carrier-class Ethernet routing. The MX2020 router enables a wide
range of business and residential applications and services, including high-speed transport
and VPN services, next-generation broadband multiplay services, and high-volume
Internet data center internetworking.
The MX2020 chassis provides redundancy and resiliency. All major hardware components
including the power system, the cooling system, the control board and the switch fabrics
are fully redundant.
The MX2020 router is 45 rack units (U) tall. One router can be installed in a four-post
rack or cabinet. The MX2020 router has 20 dedicated line card slots which means a
maximum of 20 Modular Port Concentrators (MPCs) including adapter cards (ADCs),
and Modular Interface Cards (MICs), a host subsystem consisting of 2 Control Board with
Routing Engines (CB-REs), and 8 Switch Fabric Boards (SFBs).
Up to 2 MICs can be installed in each MPC. Fully populated, the MX2020 router supports
