SRX5400 Services Gateway Software Configuration Overview
The services gateway is shipped with the Junos operating system (Junos OS) preinstalled and ready to be
configured when the device is powered on. There are three copies of the software: one on a CompactFlash
card (if installed) in the Routing Engine, one on the hard disk in the Routing Engine, and one on a USB flash
drive that can be inserted into the slot in the Routing Engine faceplate.
When the device boots, it first attempts to start the image on the USB flash drive. If a USB flash drive is
not inserted into the Routing Engine or the attempt otherwise fails, the device next tries the CompactFlash
card (if installed), and finally the hard disk.
