Supported Platforms
Line Cards Supported on MX Series Routers
Juniper Networks MX Series 3D Universal Edge Routers process incoming and outgoing packets on several different types of line cards, including Dense Port Concentrators (DPCs), Flexible Port Concentrators (FPCs) with associated Physical Interface Cards (PICs), Trio Modular Port Concentrators (MPCs) with associated Modular Interface Cards (MICs). FPCs are populated with PICs for various interface types. DPCs and MPCs combine the functions of FPCs and the PICs, and with associated physical interfaces support a variety of interface types. The configuration syntax for each type of line card is the same: type-fpc/pic/port.
FPCs and PICs
An FPC occupies two slots when installed in an MX Series router. The maximum number of supported FPCs varies per router:
- MX960 router—6 FPCs
- MX480 router—3 FPCs
- MX240 router—1 FPC
PICs provide the physical connection to various network media types. The PICs are inserted into a slot in a router. You can install PICs of different media types on the same router as long as the router supports those PICs.
MX Series 3D Universal Edge Routers support 2 PICs per Flexible PIC Concentrator (FPC). The maximum number of supported PICs varies per router:
- MX960 router—12 PICs
- MX480 router—6 PICs
- MX240 router—2 PICs
DPCs
A DPC provides multiple physical interfaces and Packet Forwarding Engines on a single board that installs into a slot within the MX Series 3D Universal Edge Routers. The maximum number of supported DPCs varies per router:
- MX960 router—12 DPC slots
- MX480 router—6 DPC slots
- MX240 router—3 DPC slots
 | Note: In the Junos OS CLI, you use the FPC syntax to configure or display information about DPCs, and you use the PIC syntax to configure or display information about Packet Forwarding Engines on the DPCs. |
In addition to Layer 3 routing capabilities, the DPCs also have many Layer 2 functions that allow MX Series routers to be used for many virtual LAN (VLAN) and other Layer 2 network applications.
Modular Port Concentrator (MPC) and Modular Interface Card (MIC) Interfaces
A Modular Port Concentrator supports two Modular Interface Card (MIC) interfaces. The maximum number of supported MPCs varies per router:
- MX960 router—12 MPC slots
- MX480 router—6 MPC slots
- MX240 router—3 MPC slots
- MX80 router—One fixed 10-Gigabit Ethernet MIC with four ports for uplink connections.
| Note: The MX80 router is available as a modular (MX80) or fixed (MX80-48T) chassis. Both chassis have a fixed Modular Interface Card (MIC) that has 3 10-Gigabit Ethernet ports. The fixed MX80 router has an additional 48 10/100/1000Base-T RJ45 ports. The modular chassis has two dedicated slots for MICs. |
