TX Matrix Plus RE-C2600 Routing Engine Description
RE-C2600 Components
Each RE-C2600 (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 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 SSD1 and SSD2 (shown in Figure 2)—Provides
secondary storage for log files, memory dumps, and rebooting the system
if the CompactFlash card fails.
 | Note:
SSD2 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 LEDs describes the functions of these LEDs.
 | Note:
For specific information about Routing Engine components (for
example, the amount of DRAM), issue the show chassis routing-engine command. |

RE-C2600 Boot Sequence
The RE-C2600 boots from the storage media in this order: the
USB device (if present), the CompactFlash card CF (if present),
the disk (if present) in slot 1 SSD1, the disk (if present)
in slot 2 SSD2, then the LAN.
