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.

Every Fortinet purchase from DataCenter360.ca is backed by hands-on services across the full lifecycle — from rollout to round-the-clock protection.
The FG-51G-SFP-PoE is the FG-50G-SFP-PoE with a 64 GB onboard SSD added. Performance is identical across both models — the SSD adds local log storage. The standard FG-51G offers the same SSD without the SFP WAN or PoE+ ports.
The 51G-SFP-PoE is the most feature-rich desktop model in the FortiGate 50G/51G series. It combines SFP WAN flexibility, 4x PoE+ device power, and 64 GB on-box logging in a single compact appliance. Step up to the 70G for higher concurrent sessions.

Mount the 51G-SFP-PoE on a desk or in a standard 1U rack tray (RM-FR-T21).
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.
The FortiGate 51G-SFP-PoE is powered by a 54VDC external adapter with a total system draw of 75.4 W average. It has 4x IEEE 802.3at PoE+ ports (WAN2 + 3 internal ports), sufficient to power up to 4 FortiAPs or other 802.3af/at devices simultaneously. For exact PoE budget allocation consult the Fortinet 50G-Series QuickStart Guide or contact DataCenter360.ca pre-sales.
Yes. The GE SFP port can serve as a primary or secondary WAN interface in FortiOS SD-WAN configurations. Pair it with the GE RJ45 WAN1 port for dual-WAN failover or load balancing. The PoE+ RJ45 WAN2 port can also serve as a third WAN link.
UTP (Unified Threat Protection) is the most popular choice, covering IPS, anti-malware, web and DNS filtering, and FortiCare Premium support. ATP covers the core threat stack only. Enterprise adds DLP, AI inline malware prevention, and the full SASE service set.
Yes. In-stock units ship from Canada with free shipping, typically delivered in 0–1 business days. Licensing and subscriptions are delivered electronically and available worldwide.
