OVERVIEW

What the FortiGate 51G-SFP-PoE is for

The FortiGate 51G-SFP-PoE is the most capable model in the FortiGate 50G/51G desktop series. Built on Fortinet’s FortiSP5 ASIC, it delivers 1.1 Gbps of threat protection and 5 Gbps firewall throughput while adding two features the standard 50G-SFP-PoE lacks: a 64 GB onboard SSD for local logging. The PoE+ implementation powers up to 4 devices (FortiAPs, VoIP phones, IP cameras) directly from the firewall, eliminating a separate PoE switch.

The WAN side provides both a GE RJ45 WAN1 port and a GE SFP slot for copper or fibre ISP handoffs. WAN2 (RJ45 PoE+) doubles as a secondary WAN for SD-WAN dual-WAN failover. Secure SD-WAN and Universal ZTNA are built into FortiOS at no extra cost. The 64 GB SSD stores logs locally without requiring FortiAnalyzer for typical small-branch deployments.

USE CASES

Where the 51G-SFP-PoE fits

Wireless branch without a PoE switch
Powers up to 4 FortiAPs, IP cameras or VoIP phones directly from 4x PoE+ ports — reducing device count and cabling at the branch.
On-box logging
64 GB onboard SSD stores local logs and reports — no FortiAnalyzer required for typical small-branch deployments.
SFP / fibre WAN
GE SFP slot connects to GPON, metro Ethernet or SFP-based ISP handoffs alongside a standard RJ45 WAN port for dual-WAN failover.
Full NGFW + SD-WAN
1.1 Gbps threat protection, IPS, SSL inspection, and integrated Secure SD-WAN powered by FortiSP5 ASIC.

FAQ

FortiGate 51G-SFP-PoE — frequently asked questions

Both models share the same FortiSP5 ASIC and deliver identical throughput (1.1 Gbps threat protection, 5 Gbps firewall). The sole difference is that the FG-51G-SFP-POE includes a 64 GB onboard SSD for local logging and reporting. Choose the 51G-SFP-PoE when you need on-box log storage alongside PoE+ and the SFP WAN port.
