Keep critical security services running with a Fortinet AC power supply built for FortiGate next-generation firewall platforms in the 4,200F to 6,000F class. This replacement unit is intended for environments where power integrity, platform fit, and fast restoration matter more than generic compatibility. Specified for FG-4200F, FG-4201F, FG-4400F, FG-4401F, and FG-6000F systems, it gives infrastructure teams a direct-fit option for maintaining service continuity across high-throughput firewall deployments. That matters when the firewall is not just another appliance, but the control point for segmentation, inspection, and east-west traffic policy. At approximately 4.41 lb, this power supply is built for enterprise hardware replacement workflows where the right part number reduces downtime and avoids guesswork. For teams managing spares, service windows, or recovery plans, the value is in exact platform alignment and the confidence that comes with a Fortinet-specified component.
