TX Matrix Plus RE-C2600 Routing Engine Overview
RE-C2600 Description
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.
| Note: SSD2 is not currently supported. |
