  • Page 10: About The Documentation

    Use this guide to install hardware and perform initial software configuration, routine maintenance, and troubleshooting for the MX204 Universal Routing Platform. After completing the installation and basic configuration procedures covered in this guide, refer to the Junos OS documentation for information about further software configuration.

  • Page 11: Merging A Full Example

    If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command. If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command.

    xiii Merging a Snippet To merge a snippet, follow these steps: 1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the file with a name, and copy the file to a directory on your routing platform. For example, copy the following snippet to a file and name the file ex-script-snippet.conf.

  • Page 19: Mx204 Router Overview

    MX204 Router Overview The Juniper Networks MX204 Universal Routing Platform is an Ethernet-optimized edge router with 400-Gbps capacity that provides both switching and carrier-class Ethernet routing. The MX204 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.

  • Page 20: System Overview

    System Overview The MX204 router is compact and one rack unit (1 U) tall. Several routers can be stacked in a single floor-to-ceiling rack for increased port density per unit of floor space. The MX204 router is a fixed-configuration router, and supports one built-in Routing Engine. The router runs on AC or DC power, with two dedicated power supply modules on each device.

  • Page 21: Mx204 Chassis

    Figure 2: Front View of the MX204 Router The MX204 has four rate-selectable ports that can be configured as 100-Gigabit Ethernet ports or 40-Gigabit Ethernet ports, or each port can be configured as four 10-Gigabit Ethernet ports (by using a breakout cable).
  • Page 22 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. NOTE: For a complete list of supported optics on MX204, see MX204 Transceivers.

  • Page 23: Mx204 Component Redundancy

    Only a fully configured router provides complete redundancy. All other configurations provide partial redundancy. The following major hardware components are redundant: Power supplies—The router supports two power supply modules. The MX204 router provides 1+1 redundancy for the system. Both AC and DC systems can withstand the failure of a single power supply without system interruption in 1+1 redundancy mode.

    Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.
