J2320 and J2350 Boot Devices
J2320 and J2350 Services Routers can boot from three devices:
■ Internal compact flash
■ External compact flash (also known as the removable compact flash)
■ USB storage device
Normally, a J2320 or J2350 Services Router boots from the internal compact flash.
If the internal compact flash fails, the router attempts to boot from the external
compact flash if it is installed. If the external compact flash is not present or fails,
the router attempts to boot from the USB storage device.
