RVS4000 Upgrade Utility 1.3

The utility should be used when the normal firmware upgrade mechanism through the Web Admin interface fails and the DIAG LED is blinking. The utility uses a layer-2 protocol to upload the firmware to RVS4000, thus there is no need to set a static IP address on the computer running this utility. However, it is required to disconnect all other network cables to the router including WAN and LAN ports.
