All Services Routers use a compact flash disk, or card, to store the JUNOS Internet software, router configuration files, and log files. The primary compact flash drive is not hot-swappable and is accessible only after you remove the cover on the back panel of the router chassis. In addition to the primary compact flash disk, J4300 and J6300 Services Routers have a slot in the front of the chassis for removable flash media. All Services Routers also support externally pluggable USB storage devices.
