Figure 15: USB Memory Device in an Routing Engine

The Routing Engine boots from the storage media in this order: the USB device, then the
CompactFlash card (if present), then the two solid state drives (SSD) and then the LAN.
The device from which the router boots is called the primary boot device, and the other
device is the alternate boot device.
NOTE: If the router boots from an alternate boot device, a yellow alarm lights
the LED on the router's craft interface.
