TX Matrix 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.
Figure 1: Routing Engine 2000 (RE-2000)
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.
