Writing this value causes the switch to reset to factory conditions. NOTHING is retained, NOT the static IP address assignments (if any), NOR any non-factory-default SNMP settings, nor any other non-factory-default settings. Given this, be warned that setting this value may very well cause all communication paths to the WS2000 to be lost. (However, if DHCP is used to obtain an IP addr on the WAN port, and only default SNMP settings are used, communications may be possible after the factory reset).
