T1600 RE-C1800 Description
The RE-C1800 Routing Engine boots from the storage media in this order: the USB device, then the CompactFlash card (if present), then SSD1, then the LAN.
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 Routing Engine ports located on the CIP.
- Extractor clips—Control the locking system that secures the Routing Engine.
