Datasheet
The router is shipped with the Junos OS preinstalled on the Routing Engine. There are
three copies of software:
•
One copy on the CompactFlash card in the Routing Engine.
•
One copy on the SSD in the Routing Engine.
•
One copy on a USB flash drive that can be inserted into the slot on the Routing Engine
faceplate.
The Routing Engine boots from the storage media in this order: the USB device (if present),
then the CompactFlash card, then the SSD, then the LAN. Normally, the router boots
from the copy of the software on the CompactFlash card.
