MX2008 Router Overview

The MX2008 Universal Routing Platform is an Ethernet-optimized router that provides both switching and carrier-class Ethernet routing. The MX2008 router supports service provider core, converged core and edge, and edge applications, and enables a wide range of business and residential and services, including high-speed transport and VPN services, next-generation broadband multiplay services, and high-volume Internet data center internetworking.

Benefits of the MX2008 Router

  • System Capacity—MX2008 delivers 40 Tbps of throughput in support of dense multirate interfaces for 100-Gigabit Ethernet, 200-Gigabit Ethernet, or 400-Gigabit Ethernet in a single chassis.

  • Always-on infrastructure base—MX Series routers ensure network and service availability with a broad set of multilayered physical, logical, and protocol-level resiliency aspects. Junos OS Virtual Chassis technology on MX Series routers supports chassis-level redundancy and enables you to manage two routers as a single element. Multichassis link aggregation group (MC-LAG) implementation supports stateful chassis, card, and port redundancy.

  • Junos Continuity and Unified In-Service Software Upgrade (Unified ISSU)—With the Junos continuity plug-in package, you can perform a smooth upgrade when new hardware is installed in your MX Series router.

    Unified in-service software upgrade (unified ISSU) enables software upgrades and changes without disrupting network traffic.

  • Junos Telemetry Interface—Using the Junos telemetry interface data, you can stream component-level data to monitor, analyze, and enhance the performance of the network. Analytics derived from this streaming telemetry can identify current and trending congestion, resource utilization, traffic volume, and buffer occupancy.

  • Power Optimization and Design Efficiency—Dynamically managed power consumption provide significant operational savings. Fan speed is dynamically monitored to consume only 20 percent of their maximum power. Power optimization enables to achieve power-to-throughput efficiency ratio of 0.3W/G.

System Overview

The MX2008 chassis provides redundancy and resiliency. All major hardware components including the power system, the cooling system, the Routing and Control Boards (RCBs), and the Switch Fabric Boards (SFBs) are fully redundant.

The MX2008 router is 24  rack units (U) tall. One router can be installed in an open-frame rack, four-post rack, or cabinet. The MX2008 router has 10 dedicated line-card slots, which means a maximum of 10 Modular Port Concentrators (MPCs) including adapter cards (ADCs) and Modular Interface Cards (MICs) can be installed on the MX2008. Up to 2 MICs can be installed in each MPC. Fully populated, the MX2008 router supports up to 20 MICs. The MX2008 host subsystem consists of two RCBs. The RCB is an integrated board and a single field-replaceable unit (FRU) that provides Routing Engine and Control Board functionality and supports virtualization. The router contains 8 Switch Fabric Boards (SFBs) that provides 7+1 redundancy.

For a list of the supported MPCs, and MICs, see the MX Series Interface Module Reference.

The MX2008 chassis contains nine power supply modules (PSMs) and two power distribution modules (PDMs) for the power feeds. Each PSM delivers 2500  W of power, and provides 8+1 redundancy. The two PDMs provide feed redundancy, with each PDM connected to primary and backup feeds separately. The MX2008 cooling system contains two fan trays, with six fans in each fan tray. The fan trays can be installed at or removed from the back of the chassis, which allows the space in the front to be used for cable management. The MX2008 supports temperature thresholds for each temperature sensor, which enables the router to precisely control the cooling, raise alarms, and shut down a FRU.

The MX2008 router is powered by the Junos Trio chipset and runs the Junos® operating system (Junos OS) for high-performance routing and switching. For a list of related Junos OS documentation, see
