T1600 RE-C1800 Description

 
Note

These Routing Engines require the LCC-CB.

RE-C1800 Components

Each RE-C1800 (Figure 1) consists of the following components:

  • CPU—Runs Junos OS to maintain the routing tables and routing protocols.

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

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

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

    Note

    The router's management Ethernet interface em0 is the interface for connecting network devices to the router through the ETHERNET port on the connector interface panel (CIP). Junos OS automatically creates em0, but you must configure its logical interface, em0.0, with a valid IP address before you can use em0 as a management port.

The faceplate of the RE-C1800 contains the following:

  • USB port—Provides a removable media interface through which you can install Junos OS manually. Junos OS supports USB version 1.1 and version 2.0 devices.

  • CompactFlash card slot—Provides primary storage for software images, configuration files, and microcode.

  • Two solid-state disk (SSD) slots—Provides secondary storage for log files, memory dumps, and rebooting the system if the CompactFlash card fails.

    Note

    DISK2 is not currently supported.

  • Reset button—Reboots the Routing Engine when pressed.

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

  • Four LEDs—CF, ONLINE,ONLINE, and ONLINE.

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

RE-C1800 Boot Order

The RE-C1800 Routing Engine boots from the storage media in this order: the USB device, then the CompactFlash card (if present), then DISK1, then the LAN.
