Each Routing Engine consists of the following components:
CPU—Runs Junos OS to maintain the router's routing tables and routing protocols..
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 Junos
OS manually. Junos OS supports USB version 1.0.
CompactFlash card—Provides primary storage for software images, configuration files,
and microcode. The CompactFlash card is fixed and is inaccessible from outside the
router.
Solid-state Drive (SSD)—Provides secondary storage for log files, memory dumps,
and rebooting the system if the CompactFlash card fails.
Interface ports—The AUX
devices. Each Routing Engine has one 10/100/1000-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.
EEPROM—Stores the serial number of the Routing Engine.
