The FortiGate 51G-SFP-POE simplifies SD-Branch architecture by integrating advanced security, SD-WAN, and power delivery with added storage capacity. Built on the Fortinet SP5 ASIC, it delivers high-speed inspection with firewall throughput of 5 / 5 / 4 Gbps (1518/512/64 byte UDP packets). With 64GB of internal SSD storage, this appliance adds onboard storage capacity within a compact desktop form factor.
Designed for flexibility and reduced hardware footprint, the FG-51G-SFP-POE features a fanless desktop form factor ideal for noise-sensitive environments. It includes a dedicated GE SFP port for fiber uplinks and multiple PoE+ capable RJ45 ports (including WAN2 and FortiLink), providing 60W of total PoE budget to power essential branch devices such as access points and IP phones directly from the firewall.
Converged Security with Storage and PoE+
Key Benefits
- Integrated SSD Storage: 64GB of onboard SSD storage in the FG-51G-SFP-POE model.
- Integrated Power over Ethernet: Provides a 60W total PoE budget across PoE+ capable ports to help power connected devices.
