Interface boards or line cards Juniper Networks (line card, interface module) allow you to expand your router or switch (modular platform, chassis) Required functional, including the necessary access ports at speeds 1GbE, 10GbE, 40GbE or 100GbE, control boards (switch control board) etc..
Interface boards Juniper represented by various modules that are compatible with a particular series (for example. interface module MS-MIC-16G compatible with the entire range Juniper MX, and the module MPC-3D-16XGE-SFPP series compatible MX240, MX480 and MX960).
interface board MIC (Modular Interface Cards) is a small-sized module that provides physical connection to various types of network devices. MIC the board can support various physical interfaces in one module. module Juniper MICs also support hot swapping and plugging. For example, in routers MX series, interface module MIC installed in the module MPC (Modular Port Concentrator), and in series from MX5 before MX104 module MPC already built in chassis.
interface module Juniper MPC (Modular Port Concentrator) provides transfer services Lkand packages. module MPC encapsulates packets and passes them through the module's outgoing interfaces MIC. everyone MPC module equipped with up to four chipsets Junos Trio, which performs the functions of management. For example, a router Juniper MX960 supports installation of up to 12 modules MPCs, and the platform MX480 before 3 MPCs. For proper operation module Juniper MPC You need to use high-performance cooling modules. Online Juniper http://www.juniper.net there is a calculator for calculating the recommended power and cooling power, for a specific series and used MPC modules.
Interface modules DPC (Dense Port Concentrators) Provides several physical interfaces and pass systems Lkand packages on a single board that fits into a slot in a router or modular chassis. module DPC accepts incoming packets and sends outgoing packets to the network.
module Juniper PIC (Physical Interface Card) installed in FPC (Flexible PIC Concentrators), similar to how they work MIC and MPC modules. PICs modules provide physical interfaces, and FPCs boards provide transfers Lkfor packets on the network. everyone FPC the module is equipped with a microchip ASIC, which performs the functions of management, and FPC supports installation of 2 modules PIC.

Interfaces
|
Syntax: ge-fpc/pic/port where:
- fpc: Slot in the router where the DPC is installed
- pic: 0 (bottom left row of 10 ports), 1 (bottom right row of 10 ports), 2 (top left row of 10 ports), or 3 (top right row of 10 ports) when installed horizontally
- port: 0 through 9
For example, ge-1/3/0 is the interface for port 0 in the top right row of 10 ports on a DPC installed in slot 1.
For information on the interface numbering, see the DPC Port and Interface Numbering topic for the respective MX router.
