The router is shipped with the Junos operating system (OS) preinstalled and ready to be
configured when the router is powered on. Two 16-MB internal NAND Flash memory
devices are located on the baseboard for BIOS storage. The USB storage device can be
inserted into the USB slot on the chassis faceplate. The router also supports two built-in
M.2-based solid-state drive (SSD) slots. These two SSD devices act as the primary boot
devices ( SSD0 and SSD1 ). When the router boots, it first attempts to start the Junos OS
image on the USB flash drive if it detects one. If a USB flash drive is not inserted into the
