MX2020 Modular Port Concentrator (MPC) Description
Designed for flexibility, MX2000 Modular Port Concentrators (MPCs) leverage the Junos Trio chipset to deliver the industry’s highest Gigabit Ethernet density, as well as the flexibility of modular interfaces across the MX Series portfolio. These advanced capabilities allow mix and match interfaces to create service-specific and “pay as you grow” configurations. The MPCs house the packet forwarding engines to deliver up to 120-Gigabit Ethernet of comprehensive Layer 3 routing (IPv4 and IPv6), and Layer 2 switching. The MPCs also support inline services and advanced Hierarchical QoS (H-QoS) per MX Series slot.
Modular Interface Cards (MICs) install into the MPCs to provide the physical interfaces. You can install up to two MICs of different media types on the same MPC as long as the MPC supports those MICs.
The MX2020 router also supports fixed port MPCs.
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 Calculating DC Power Requirements for MX2020 Routers and Calculating AC Power Requirements for MX2020 Routers.
The router has 20 dedicated line card slots for MPCs. MPCs install
vertically in the front of the router. The dedicated slots are numbered
9 (bottom), and
19 (top), left to right.
An MPC can be installed in any line card slot.
When an MPC slot is not occupied, you need to install a blank MPC panel.
MPCs are hot-removable and hot-insertable. When you install an MPC in an operating router, the CB-RE downloads the MPC software. The MPC runs its diagnostics and enables the Packet Forwarding Engines housed on the MPC. Forwarding on other MPCs continues uninterrupted during this process.
Each MPC consists of the following components:
MIC card carrier, which includes two MIC slots (excludes the fixed configuration MPC).
Two Gigabit Ethernet interfaces that allow control information, route information, and statistics to be sent between the routing engine and the CPU on the MPCs.
Up to four Junos Trio chipsets, which perform control functions tailored to the MPC’s media type.
Backplane connectors and power circuitry.
Online button located on the craft interface, which takes the MPC online or offline when pressed.
OK/FAILLED on the MPC faceplate. For more information about the LEDs for your MPC, refer to the MX Series 5G Universal Routing Platform Interface Module Reference.
