MX480 Modular Port Concentrator (MPC) Description

Modular Port Concentrators (MPCs) provide packet forwarding services. The MPCs are inserted into a
slot in a router. Modular Interface Cards (MICs) provide the physical interfaces and install into the MPCs.
You can install up to two MICs of different media types on the same MPC as long as the MPC supports
those MICs.
A specialized fixed configuration MPC provides higher port density over MICs and combines packet
forwarding and Ethernet interfaces onto a single line card. The fixed configuration MPC is inserted into a
slot in a router and contains no slots for MICs.
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. Before transmitting
outgoing data packets through the MIC interfaces, the MPCs encapsulate the packets received. Each MPC
is equipped with up to four Junos Trio chipsets, which perform control functions tailored to the MPC's
media type. The MPCs interface with the power supplies and Switch Control Boards (SCBs). You must
install redundant SCBs to support full line-rate.
The MX480 router supports up to six MPCs. You must install a high-capacity fan tray to use an MPC. For
power requirements, see
The router has six dedicated line card slots for DPCs, MPCs, or FPCs that are numbered 0 through 5 bottom
to top. An MPC can be installed in any slot on the router that supports MPCs. You can install any
combination of line card types in the router.
When a slot is not occupied by an MPC or other line card, you must insert a blank DPC panel to fill the
empty slot and ensure proper cooling of the system.
