MX10003 Routing and Control Board

MX10003 Routing and Control Board (RCB) Description

The host subsystem provides routing protocol processes, as well as software processes that control the router’s interface, the chassis components, system management, and user access to the router. These routing processes run on top of a kernel that interacts with the Packet Forwarding Engine. The MX10003 host subsystem consists of two Routing and Control Boards, or RCBs. The RCB is an integrated board and a single FRU that provides Routing Engine (RE) and Control Board (CB) functionality. The RE performs all route-processing functions, whereas the CB performs chassis control and management plane functionality. The RCB provides control plane functions. You can install one or two RCBs on the router. Each RCB functions as a unit.

Note:

Install two RCBs for redundant protection. If you install only one RCB, you can install it in slot 0 or slot 1. By default, slot 0 functions as the primary.

CAUTION:

If one of the RCBs fails, do not remove the failed RCB until you have a replacement or blank panel to install.

The MX10003 router supports the following RCBs:

  • JNP10003-RE1

  • JNP10003-RE1-LT

This topic covers:

Routing and Control Board Functions

The Routing and Control Board integrates the Routing Engine and Control Board functions into a single management unit. Each RCB provides all the functions needed to manage the operation of the modular chassis:

  • System control functions such as environmental monitoring

  • Routing Layer 2 and Layer 3 protocols

  • Communication to all components such as line cards, power, and cooling

  • Transparent clocking

  • Alarm and logging functions

Routing and Control Board Components

Each RCB consists of the following internal components:

  • High-performance 1.6-GHz Intel 8 Core X86 CPU

  • 64-GB DDR4 RAM

  • 100-GB SATA SSD

The MX10003 router with JNP10003-RE1-LT RCB supports only Junos Limited image. The Junos Limited image does not have data-plane encryption and is intended only for countries in the Eurasian Customs Union because these countries have import restrictions on software containing data-plane encryption. Unlike the Junos Worldwide image, the Junos Limited image supports control plane encryption through Secure Shell (SSH) and Secure Sockets Layer (SSL), thus allowing secure management of the system. The Limited Restriction RCB boots only the encryption free Junos software and fails to boot if the fully encrypted Junos software is used for booting. The Junos upgrade and VMHost upgrade using non-limited version of Junos software fails on the JNP10003-RE1-LT RCB.

The command show chassis hardware [models | clei-models | extensive] displays the model number and helps identifying the different SKUs. An alarm, Mixed Master and Backup RE types is displayed when dissimilar Routing Engines are present on the chassis (see Chassis Alarms).

RCB Interface Ports

The ports located on the RCB, connect the RCB to one or more external devices on which system administrators can issue Junos OS CLI commands to manage the router. In addition, ports to connect external clock interfaces for BITS and GPS function are also available on the RCB.

The RCB interface ports with the indicated labels function are as follows (see Figure 1):

  • CON—Connects the RCB to a system console through a serial cable with an RJ-45 connector.

  • MGMT—Connects the RCB through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management. The port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or 1000-Mbps connections. Two small LEDs (an activity LED and a link LED) on the port indicate the connection in use.

    The link LED is:

    • lit amber (steady) when the 1000-Mbps link is up.

    • lit green (steady) when the 100-Mbps link is up.

    • off when the 10-Mbps link is up.

    The activity LED is:

    • lit green (blinking) when traffic is passing through the port.

    • lit green (steady) when traffic is not passing through the port.

    Both activity and link LEDs are off when the link is down.

  • BITS—Building-integrated timing supply (BITS) external clocking interface for connection to external clocking devices.

  • ToD—Time-of-day (TOD) port on the front panel of the router allows you to connect external timing signal sources.

    Note:

    This port is reserved for future use.

  • 10MHZ (one input and one output)—The 10-MHz timing connectors on the front panel of the router connect to external clock signal sources. The clocking ports provide the synchronized output clocks from any one of the reference clock inputs based on the clock’s priority.

  • PPS (one input and one output)—1-pulse-per-second (PPS) connectors on the front panel of the router connect to external clock signal sources. The clocking ports provide the synchronized output clocks from any one of the reference clock inputs based on the clock’s priority.

  • USB—Provides a removable media interface through which you can install Junos OS manually. Junos OS supports USB version 1.0 and later.

MX10003 RCB LEDs

The Routing and Control Board (RCB) is an integrated board and a single FRU that provides Routing Engine and Control Board functionality.

The LEDs—labeled ONLINE, MST, OK/FAIL, LINK, GPS, BITS—are located directly on the faceplate of the RCB. Table 1 describes the functions of the Routing Engine interface of the RCB.

Note:

The functioning of the MX10003 router is contolled by the RCB, and the LEDs present on the RCBs displays the status and functioning of the MX10003 chassis.
