The Modular Port Concentrators (MPCs) provides packet forwarding services. The MPCs
install into an adapter card (ADC) which in turn connects to the backplane. Modular
Interface Cards (MICs) provide the physical interfaces and install into the MPCs. The
user can install up to two MICs of different media types on the same MPC as long as the
MPC supports those MICs.
NOTE: The MX2020 router also supports fixed port MPCs.
MICs receive incoming packets from the network and transmit outgoing packets to the
network. During this process, each MIC performs framing and high-speed signaling for
its media type. Each MPC is equipped with up to four Junos Trio chipsets, which perform
control functions tailored to the MPC's media type.
The MX2020 router supports up to 20 MPCs. For power requirements, see
DC Power Requirements for MX2020 Routers" on page 180
Requirements for MX2020 Routers" on page
The router has 20 dedicated line card slots for MPCs. MPCs install vertically in the front
of the router. The dedicated slots are numbered
(top), left to right. An MPC can be installed in any line card slot. The user can install any
combination of MPC types in the router.
