T1600 RE-2000 Description

 

The RE-2000 boots from the storage media in this order: the USB device, then the CompactFlash card (if present), then the hard disk, then the LAN.

Each RE-2000 (shown in Figure 1) consists of the following components:

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

  • DRAM—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 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 the Routing Engine ports located on the 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 RE-2000 contains the following:

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

  • Reset button—Reboots the Routing Engine when pressed.

  • Offline button—Takes the Routing Engine offline when pressed.

  • Extractor clips—Control the locking system that secures the Routing Engine.

  • LEDs—HDD and ONLINE indicate activity on the hard disk drive and the status of the Routing Engine.
