MX240 Router Overview
The MX240 3D Universal Edge Router is an Ethernet-optimized edge router that provides
both switching and carrier-class Ethernet routing. The MX240 enables a wide range of
business and residential applications and services, including high-speed transport and
VPN services, next-generation broadband multiplay services, high-speed Internet and
data center internetworking.
The MX240 router is five rack units (U) tall. Several routers can be stacked in a single
floor-to-ceiling rack, for increased port density per unit of floor space.
Fully populated, the MX240 provides a maximum aggregate switch fabric capacity of
up to 1.92 Tbps and line-rate throughput for up to 48 10-Gigabit Ethernet ports, or four
100-Gigabit Ethernet and eight 10-Gigabit Ethernet ports, or twelve 40-Gigabit Ethernet
ports.

The router provides two dedicated line card slots for Dense Port Concentrators (DPCs),
Modular Port Concentrators (MPCs), or Flexible PIC Concentrators (FPCs). DPCs and
MPCs each install into a single line-card slot. The FPC installs into both slots. The router
also providesone dedicated slot for a Switch ControlBoard (SCB), and one multifunction
slot for either one DPC, MPC, or SCB. Optionally, an FPC can be installed in both the
