RE-S-X6-64G and RE-S-X6-64G-LT Routing Engine Components

In MX240 routers with dual Routing Engines, both the Routing Engines must be RE-S-X6-64G Routing
Engines.
Each RE-S-X6-64G Routing Engine (shown in
CPU—Runs Junos OS to maintain the routing tables and routing protocols.
EEPROM—Stores the serial number of the Routing Engine.
DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.
One 10-Gigabit Ethernet interface between Routing Engine and Switch Control Board.
Two 50 GB slim Solid State Drives—SSD1 (primary) and SSD2 (secondary)—Provide storage for software
images, configuration files, microcode, log files, and memory dumps. The Routing Engine reboots from
SSD2 when boot from primary SSD fails.
Two USB ports (USB1 and USB2)—Provide a removable media interface through which you can install
Junos OS manually. The Junos OS supports USB versions 3.0, 2.0, and 1.1.
Interface ports—The AUX, CONSOLE, and MGMT provide access to management 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.
RESET Button—Reboots the Routing Engine when pressed.
ONLINE/OFFLINE Button—Makes the Routing Engine online or offline when pressed.
Extractor clips—Control the locking system that secures the Routing Engine.
