RE-S-1800 Routing Engine Boot Sequence
The router is shipped with 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 hard disk 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 Solid State Disk (SSD), then the LAN. Normally,
the router boots from the copy of the software on the CompactFlash card.
