MX10003 System Overview

 

The Juniper Networks MX10003 Universal Routing Platform is an Ethernet-optimized edge router with 2.4Tb capacity that provide both switching and carrier-class Ethernet routing. The MX10003 router runs 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 Layer 2/Layer 3 packet forwarding, buffering, and queuing.

Benefits of the MX10003 Router

  • Space-optimized, power-efficient cloud-era routing platform—The MX10003 caters to the edge and Metro Ethernet needs of service providers, mobile operators, multiple-service operators in space- and power-constrained environments. Delivering 2.4 Tbps of throughput in just three rack units (3 U), the MX10003 delivers industry-leading port density and performance while consuming just 0.9 watts per gigabit of throughput.

  • Integrated high-precision timing—The MX10003 router eliminates the need for external clocks by supporting highly scalable and reliable hardware-based timing including Synchronous Ethernet for frequency, and Precision Time Protocol (PTP) for frequency and phase synchronization. The router uses a hybrid mode, combining Synchronous Ethernet and PTP, to achieve a high level of frequency (10 ppb) and phase (<1.5 uS) accuracy.

  • Simplified management through Junos Fusion—You can use the MX10003 as aggregation devices in a Junos Fusion Provider Edge deployment, where EX Series and QFX Series switches function as satellite devices.

MX10003 Router Hardware Overview

The MX10003 router contains modular Routing Engines and multiple Packet Forwarding Engines. The Packet Forwarding Engine has two “pseudo” Flexible PIC Concentrators (FPC 0 and FPC1). The single Packet Forwarding Engine takes care of both ingress and egress packet forwarding.

The MX10003 is a compact router, three rack units (3U) tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space.

The router provides two dedicated line card slots for Modular Port Concentrators (MPCs). MPCs install into the line-card slots. The router supports two redundant Routing and Control Board (RCB). The RCB houses the Routing Engine and Control Board. The router is powered by six dedicated AC/DC power supply modules. Cooling is handled by four fan modules.

Starting in Junos OS Release 18.3R1, you can use the Mellanox 10-Gbps pluggable adapter (QSFP+ to SFP+ adapter or QSA; model number: MAM1Q00A-QSA) to convert four lane-based ports to a single lane-based SFP+ port. The QSA adapter has the QSFP+ form factor with a receptacle for the SFP+ module. Use the QSA adapter to convert a 40-Gbps port to a 10-Gbps or a 1-Gbps port. You can configure the 4x10 Gbps ports on the fixed pic (6XQSFPP) and the QSFP28 ports on the non-MACSEC MIC (JNP-MIC1) in the 1-Gbps mode, when the SFP is plugged in through the QSA adapter.

Note
  • The interface name prefix must be xe.

  • Rate selectability at PIC level and port level does not support 1-Gbps speed.

  • For the link to come up, you must configure the no-auto-neg statement on the egress interface.

MX10003 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:

  • Host subsystem—The host subsystem consists of two Routing and Control Boards (RCBs). The RCB is an integrated board and a single FRU that provides Routing Engine and Control Board functionality. The router can have one or two host subsystems. If two host subsystems are installed, one functions as the primary and the other functions as the backup. If the primary host subsystem (or either of its components) fails, the backup can take over as the primary. The RCB installed in slot 0 functions as the default primary.

  • Power supplies—The router supports six power supplies. Table 4 shows the power redundancy supported on the AC and DC powered router for minimum operation. Minimum power supplies required for non-redundant operation is 2 for AC (high), 3 for DC, and 4 for AC (low). With additional power supplies, it provides N+1 and N+N redundancy for the system. Both AC and DC systems can withstand the failure of a single power supply without system interruption in N+1 redundancy mode. If one power supply fails in a fully redundant system, the other power supply can provide full power to the router indefinitely.

    DC

    3+3

  • Cooling system—The cooling system has a total of four fan modules, which are controlled and monitored by the host subsystem. A fully configured router needs all the four fan modules to operate normal. The fan modules are at the rear and are used to cool the router. If a fan fails or the temperature rises above the temperature threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range.

    Caution

    For a fully configured router, all the four fan modules must be operational, and in the event of any fan module failure the failed fan module must be replaced immediately.

MX10003 Field-Replaceable Units

Field-replaceable units (FRUs) are router components that can be replaced at the customer site (see Table 5). Replacing most FRUs requires minimal router downtime. The router uses the following types of FRUs:

  • Hot-removable and hot-insertable FRUs—You can remove and replace these components without powering off the router or disrupting the routing functions.

  • Hot-pluggable FRUs—You can remove and replace these components without powering off the router, but the routing functions of the system are interrupted when the component is removed.

Table 5 lists the FRUs for the router.
