TX Matrix Plus RE-C2600 Routing Engine Description


RE-C2600 Routing Engine Components

Each RE-C2600 Routing Engine (shown in Figure 1) consists of the following components:

  • CPU—Runs Junos OS to maintain the TX Matrix Plus 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 the external management devices (console, laptop, or terminal server) connected to the TXP Routing Engine ports located below the Routing Engine on the TXP-CB.

The faceplate of the RE-C2600 Routing Engine contains the following:

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

  • CompactFlash card slot, CF (shown in Figure 2)—Provides primary storage for software images, configuration files, and microcode.

  • Two solid-state disk slots, Disk1 and Disk2 (shown in Figure 2)—Provide secondary storage for log files, memory dumps, and rebooting the system if the CompactFlash card fails.


    Disk2 is not currently supported.

  • 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—TX Matrix Plus RE-C2600 Routing Engine LEDs describes the functions of these LEDs.


For specific information about Routing Engine components (for example, the amount of DRAM), issue the show chassis routing-engine command.

RE-C2600 Routing Engine Boot Sequence

The RE-C2600 Routing Engine boots from the storage media in this order: the USB device (if present), the CompactFlash card CF (if present), the disk (if present) in the Disk1 slot, then the LAN.


The Disk2 slot is not currently supported.
