Before you install a service node, you must create a Service Node Installation Image on a USB device. You can create either a USB image or an ISO image. Each new LCDN or LMS service node boots the first time from the Service Node Installation Image to install the required service node software on each service node. After the installation is complete, you must remove the USB device so that from that point forward the node boots off its hard disk.
