T1600 RE-600 Description

 

The RE-600 boots from the storage media in this order: the PC Card (if present), then the CompactFlash card (if present), then the hard disk.

Routing Engine 600

Each Routing Engine 600 (shown in Figure 1) consists of the following components:

  • CPU—Runs Junos OS to maintain the router's routing tables and routing protocols. It has a Pentium-class processor.

  • SDRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.

  • CompactFlash card—Provides primary storage for software images, configuration files, and microcode. The fixed CompactFlash card is inaccessible from outside the router.

  • Hard disk—Provides secondary storage for log files, memory dumps, and rebooting the system if the CompactFlash card fails.

  • EEPROM—Stores the serial number of the Routing Engine.

  • Interfaces for out-of-band management access—Provide information about Routing Engine status to devices (console, laptop, or terminal server) connected to ports located on the Connector Interface Panel (CIP).

    Note

    The router's management Ethernet interface fxp0 is the interface for connecting network devices to the router through the ETHERNET port on the connector interface panel (CIP). Junos OS automatically creates fxp0, but you must configure its logical interface, fxp0.0, with a valid IP address before you can use fxp0 as a management port.

The faceplate of the Routing Engine 600 contains the following:

  • One PC Card slot—Accepts a removable PC Card, which stores software images for system upgrades.

    A slot labeled PC CARD on the Routing Engine faceplate accepts a Type I PC Card, as defined in the PC Card Standard published by the Personal Computer Memory Card International Association (PCMCIA). The TX Matrix router is shipped with a PC Card that contains Junos OS. The PC Card can be used to copy Junos OS from the PC Card onto the Routing Engine. You can also copy Junos OS from the Routing Engine onto a PC Card, for example, to create a backup copy of upgrade software that you have obtained from Juniper Networks. Instructions for copying software to a PC Card are available at the Juniper Networks Support Web site (https://www.juniper.net/support/); after logging in, navigate to the Customer Support Center, then to the download page for Junos OS.

    Note

    The software on a PC Card is loaded only onto the Routing Engine into which the PC Card is inserted. It is not automatically copied to the other Routing Engine.

  • Reset button—Reboots the Routing Engine when pressed.

  • HD LED.
