SRX5600 Services Gateway Routing Engine Components

The Routing Engine consists of the following components:

• CPU—Runs Junos OS to maintain the services gateway's 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.
• USB port—Provides a removable media interface through which you can install the Junos OS manually. Junos supports USB version 1.0.
• Internal flash disk—Provides primary storage for software images, configuration files, and microcode. The disk is a fixed compact flash and is inaccessible from outside the services gateway.
• Hard disk—Provides secondary storage for log files, memory dumps, and rebooting the system if the internal compact flash disk fails.
• HDD LED—Indicates disk activity for the hard disk drive.
• Management ports—Each Routing Engine has one 10/100-Mbps Ethernet port for connecting to a management network, and two asynchronous serial ports—one for connecting to a console and one for connecting to a modem or other auxiliary device. The interface ports are labeled AUX, CONSOLE, and ETHERNET.
• EEPROM—Stores the serial number of the Routing Engine.
• Reset button—Reboots the Routing Engine when pressed.
• Online/Offline button—Not supported in the current release.
• Extractor clips—Used for inserting and extracting the Routing Engine.
• Captive screws—Secure the Routing Engine in place.
