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
following components:
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
you can install Junos OS manually. The Junos OS supports USB versions 3.0, 2.0, and
1.1.
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.
Button—Reboots the Routing Engine when pressed.
RESET
ONLINE/OFFLINE Button—Makes the Routing Engine online or offline when pressed.
Extractor clips—Control the locking system that secures the Routing Engine.
