Industrial Gigabit 3-Port PoE Ethernet Switch with SFP - Robust

In this review the focus is on a compact industrial switch built for small PoE networks where reliability matters. The Industrial Gigabit 3-Port PoE Ethernet Switch with SFP proved itself as a practical, no-nonsense device for powering and connecting a handful of IP devices; its single biggest selling point is the combination of full gigabit RJ45 ports with a dual-mode SFP slot and genuine industrial resilience, making it useful in remote enclosures or edge sites where space and power redundancy are priorities.

Key Features

• 3 Gigabit RJ45 ports: Three 10/100/1000Base-T ports deliver full gigabit throughput for cameras, access points or controllers without a speed bottleneck.
• PoE+ support: Each RJ45 port supplies IEEE802.3af/at PoE up to 30W per port, allowing higher-power devices to run without separate power adapters.
• SFP dual-mode slot: The single SFP slot auto-detects 100Base-FX or 1000Base-X SFP modules so you can add fiber connectivity for longer links or noise-immune runs.
• Redundant DC input: Wide 12-48V DC input with dual power terminals keeps the switch online if one power source fails, improving uptime in critical installations.
• Industrial rating: IP40 housing, -40C to 80C operating range and 6KV lightning protection mean the switch tolerates harsh environments better than consumer gear.
• Flexible mounting: Aluminum housing with 35mm din-rail and wall mount kit simplifies installation in cabinets, on rails or on enclosure walls.

Who It's For

The switch is aimed at installers and integrators who need a small PoE hub for up to three powered devices plus an uplink over copper or fiber; typical uses include small CCTV clusters, roadside cabinets, access point backhaul and industrial automation endpoints. Its rugged temperature range and lightning protection make it suitable for outdoor enclosures and factory floors where consumer switches would fail.

It is not targeted at large office networks or users who need managed features like VLANs, QoS configuration or SNMP monitoring; if you need deep traffic control or many ports, a managed or modular switch line is a better fit.

Pros & Cons

Pros

• Compact footprint with three gigabit PoE+ ports and a flexible SFP uplink for fiber or long-distance links.
• Industrial-grade power and protection: wide 12-48V DC input, dual power terminals and lightning protection for reliable uptime.
• High per-port PoE budget: up to 30W per port and 90W total supports higher-draw devices like PTZ cameras.
• Simple installation with din-rail and wall mount accessories included.

Cons

• Unmanaged design means no VLAN, QoS tuning or remote monitoring for larger or security-conscious deployments.
• Single SFP slot limits fiber uplink flexibility when multiple fiber ports are required.

Frequently Asked Questions

Does this switch deliver PoE on all copper ports?
Yes, all three RJ45 ports support IEEE802.3af/at PoE with up to 30W per port and a 90W total budget.

Can the SFP slot accept both 100Base and 1000Base modules?
Yes, the SFP slot is dual-mode and auto-detects 100Base-FX or 1000Base-X SFP modules.

Is this device suitable for outdoor enclosures?
It is built to industrial specs with a wide temperature range and lightning protection, but the IP40 rating requires a weatherproof enclosure for direct outdoor exposure.
