De-energize the AC power source before disconnecting or replacing this unit to avoid electrical hazards or network disruptions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the significance of the \"S4\" suffix on this gateway model?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The \"S4\" designator specifies the mechanical and electrical revision level of the unit, indicating updated internal signal filtering circuitry and improved component tolerances over earlier revisions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can this unit be configured for 220 V AC utility lines?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. This specific model configuration (F2121) is rated strictly for 100 to 120 V AC input ranges.
