Services Routers Hardware Guide

■ 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.
