Removing and Installing the USB Storage Device
USB storage devices are optional components on J-series Services Routers. If
installed, a USB storage device provides secondary storage for the router. It can
accommodate software images, configuration files, and microcode. If the primary
compact flash disk fails on startup, and the removable compact flash disk is not
installed or fails, the router boots from the USB storage device.
For information about configuring the USB storage device, see the J-series Services
Router Administration Guide.
