Know your gear
- One 10-Gigabit Ethernet interface between the 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.
