RE-S-X6-128G Routing Engine Components

In routers with dual Routing Engines, both Routing Engines must be RE-S-X6-128G Routing
Engines.
Each RE-S-X6-128G 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 the Routing Engine and Switch Control
Board.
Two 50-GB slim solid-state drives—
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 ( and
USB1
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
