The Juniper Networks MX5, MX10, MX40, and MX80 3D Universal Edge Routers are Ethernet-optimized edge routers that provide both switching and carrier-class Ethernet routing. The MX5, MX10, MX40, and MX80 routers run Junos operating system (Junos OS), enabling a wide range of business and residential applications and services, including high-speed transport and virtual private network (VPN) services, next-generation broadband multiplay services, and high-volume Internet data center internetworking. Each router provides full duplex, high-density Ethernet interfaces and high- capacity switching throughput and uses the Junos Trio chipset for increased scalability of L2/L3 packet forwarding, buffering, and queuing. The routers each contain a built-in Routing Engine and one Packet Forwarding Engine. The Packet Forwarding Engine has two “pseudo” Flexible PIC Concentrators (FPC 0 and FPC1). Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress packet forwarding. The routers are compact and two rack units (U) tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space. For scalable configuration options you can install a variety of Modular Interface Cards (MICs) in the two front slots of the router, and the optional Multiservices MIC can be installed in the rear slot. Software licenses allow you to upgrade from one router to another without a hardware upgrade. The ports are restricted based on the router’s associated license as follows: MX5 router: Allows usage of the MIC slot labeled 1/MIC 0, which comes prepopulated with the Gigabit Ethernet MIC with SFP. Figure 1: MX5 Router
MX10 router: Allows usage of the MIC slot labeled 1/MIC 0, which comes prepopulated with the Gigabit Ethernet MIC with SFP and the second MIC slot labeled 1/MIC 1.
Figure 2: MX10 Router
MX40 router: Allows usage of the front MIC slots and ports 0 and 1 of the built-in 10-Gigabit Ethernet MIC (labeled 0/MIC 0).
Figure 3: MX40 Router
MX80 router: Allows usage of all MIC slots (front and back) and all four ports of the built-in 10-Gigabit Ethernet MIC (labeled 0/MIC 0).
Figure 4: MX80 Router
A fixed version of the MX80 router (model number: MX80-48T) has 48 fixed 10/100/1000Base-T RJ45 ports in place of the MIC slots.
