MX480 Router Description
TheMX4803DUniversalEdgeRouterisanEthernet-optimizededgerouterthatprovides both switching and carrier-class Ethernet routing. The MX480 router has a capacity of up to 720 gigabits per second (Gbps), full duplex. The MX480 router enables a wide rangeofbusinessandresidentialapplicationsandservices,includinghigh-speedtransport and VPN services, next-generation broadband multiplay services, and high-volume Internet data center internetworking.
The MX480 chassis provides redundancy and resiliency. The hardware system is fully redundant,includingpowersupplies,RoutingEngines,andSwitchControlBoards(SCBs).
The MX480 router is eight rack units (U) tall. Five routers can be stacked in a single floor-to-ceilingrack,forincreasedportdensityperunitoffloorspace.Therouterprovides eight slots that can be populated with up to six Dense Port Concentrators (DPCs) or Modular Port Concentrators (MPCs), three Flexible PIC Concentrators (FPCs), and two SCBs. Each FPC holds up to two PICs and each MPC holds up to two Modular Interface Cards (MICs).
Fully populated, the MX480 router provides an aggregate throughput of up to 720 Gbps, with line-rate throughput on 72 10-Gigabit Ethernet ports, or oversubscribed forwarding at a gross ratio of 3:4 on all 96 10-Gigabit Ethernet ports.
EachDPCincludeseithertwoorfourPacketForwardingEngines.EachPacketForwarding Engine enables a throughput of 10 Gbps. Many types of DPCs are available. For a list of the DPCs supported, see the MX Series 3D Universal Edge Routers Line Card Guide.
The MX480 supports up to 3 FPCs containing up to 6 PICs or up to 6 MPCs containing up to 12 MICs. For a list of the supported line cards, see the MX Series 3D Universal Edge Routers Line Card Guide.
The connections between DPCs, FPCs, MPCs, and SCBs are organized in three groups:

•Control plane—Gigabit Ethernet links between the combined SCBs/Routing Engines and each DPC, FPC, or MPC. All board-to-board information is passed over Ethernet except for low-level status and commands.
•Management signals—Provide for low-level status diagnostic support.

MX480 Component Redundancy
A fully configured router is designed so that no single point of failure can cause the entire system to fail. Only a fully configured router provides complete redundancy. All other configurations provide partial redundancy. The following major hardware components are redundant:
•Hostsubsystem—ThehostsubsystemconsistsofaRoutingEnginefunctioningtogether with an SCB. The router can have one or two host subsystems. If two host subsystems are installed, one functions as the master and the other functions as the backup. If the master host subsystem (or either of its components) fails, the backup can take over as the master. To operate, each host subsystem requires a Routing Engine installed directly into in an SCB.
IftheRoutingEnginesareconfiguredforgracefulswitchover,thebackupRoutingEngine automaticallysynchronizesitsconfigurationandstatewiththemasterRoutingEngine. Any update to the master Routing Engine state is replicated on the backup Routing Engine.IfthebackupRoutingEngineassumesmastership,packetforwardingcontinues throughtherouterwithoutinterruption.Formoreinformationaboutgracefulswitchover, see the Junos OS System Basics Configuration Guide.
•Power supplies—In the low-line (110 V) AC power configuration, the router contains three or four AC power supplies, located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right). Each AC power supply provides power to all components in the router. When three power supplies are present, they share power almost equally within a fully populated system. Four AC power supplies provide full powerredundancy.Ifonepowersupplyfailsorisremoved,theremainingpowersupplies instantly assume the entire electrical load without interruption. Three power supplies provide the maximum configuration with full power for as long as the router is operational.
In the high-line (220 V) AC power configuration, the router contains two or four AC power supplies located horizontally at the rear of the chassis in slots PEM0 through

Ifonepowersupplyfailsorisremoved,theremainingpowersuppliesinstantlyassume theentireelectricalloadwithoutinterruption.Twopowersuppliesprovidethemaximum configuration with full power for as long as the router is operational.
In the DC configuration, two power supplies are required to supply power to a fully configured router. One power supply supports approximately half of the components in the router, and the other power supply supports the remaining components. The addition of two power supplies provides full power redundancy. If one power supply fails or is removed, the remaining power supplies instantly assume the entire electrical load without interruption. Two power supplies provide the maximum configuration with full power for as long as the router is operational.
•Coolingsystem—Thecoolingsystemhasredundantcomponents,whicharecontrolled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely.
