Installation using a USB storage device. We recommend this method if console access
to the system is available and the system can be physically accessed to plug in a USB
storage device. See Installing Junos OS Using a USB Storage Device on ACX Series

available. This installation can be performed remotely. See Installing Junos OS Upgrades
