Overview

The S8G02G2GFI/GFID is the full-gigabit flagship of the 8-port line: 8 Gigabit PoE ports paired with 2 Gigabit RJ45 uplinks and 2 Gigabit SFP slots, so a project with high-bitrate 4K cameras and a fiber backbone can use both at once. Run the RJ45 uplinks to a nearby switch and the SFP ports to two separate fiber runs for path redundancy, or split camera traffic across copper and fiber to keep any single link from getting overloaded. Every PoE port still delivers up to 30W under IEEE 802.3af/at, and the fanless metal case keeps it silent under load. Choose the 96W S8G02G2GFI for typical loads or the 120W S8G02G2GFI, which adds a watchdog auto-reset, for heavier PTZ/IR loads.

Is This the Right Fit?

Six real deployment scenarios matched to this model's actual datasheet specifications.

Multi-Story GuesthousesFiber riser between floors on the SFP ports, ground-floor lobby cameras on the RJ45 uplink.

Farms with Several BuildingsHouse, barn and storage shed each on their own fiber run into the two SFP ports for a redundant path back to the office.

Construction Site Command CentersTemporary office linked to two separate site trailers over fiber, cameras on gate and material yard on copper.

Small School Campuses (Two Blocks)Fiber uplinks connect the classroom block and the admin block back to a shared NVR closet.

Gas Stations with a Car Wash BayFiber uplink to the wash bay switch, copper uplink handles the main forecourt cameras.

Small Clinic Outbuilding ClustersFiber connects a detached ward or lab building back to the main NVR room over two redundant SFP paths.

Not a good fit if:

Not a managed switch -- no VLAN segmentation, spanning-tree, or web management interface. Choose a managed model if the project needs VLANs or loop-prevention protocols.
No ring-network redundancy protocol -- built for star, tree, and bus topologies, not self-healing ring recovery.
Commercial -10°C to +70°C rated in a desktop/wall-mount metal case without 19-inch rack ears -- not for extreme industrial wide-temperature sites or standard 19-inch rack rows.

Key Features

IEEE 802.3af/at PoE+, 30W per Port — Delivers up to 30W on every port -- runs PTZ domes, IR-illuminated cameras, and PoE access points with no separate injector.
Smart Powered-Device Detection — Identifies a genuine PD before energizing the port, so a miswired cable or non-PoE device won't get fried and idle ports don't waste power.
All-Gigabit Access + RJ45/Dual SFP Uplink — Run copper and fiber together, or split traffic across two paths for extra uplink headroom.
Gigabit to Every Camera — Full 1000M on all PoE ports, so 4K and multi-sensor units keep their frame rate instead of dropping to 100M.
One Cable for Power and Data — No separate power run to pull -- camera power and video ride the same Cat5e/6 cable, cutting cable cost and install labor on every point.
Fanless, Silent, Maintenance-Free — Sealed metal enclosure with zero moving parts -- silent, dust-tolerant, and maintenance-free tucked in a back office, ceiling void, or equipment cabinet.
96W or 120W, Watchdog on the High-Power Version — Available in 96W and 120W PoE power budgets, with the 120W version adding a watchdog auto-reset for heavier PTZ/IR loads -- pick the version that matches the job.

8-Port Gigabit PoE Switch FAQ — S8G02G2GFI

How many cameras can the S8G02G2GFI power, including 4K models?

All 8 gigabit PoE ports power devices simultaneously under IEEE 802.3af/at. The 120W version averages 15W per port; typical IP cameras draw 4–12W, so 8 cameras fit comfortably. Each camera also gets a full gigabit link, which suits high-bitrate 4K streams, and a single port can supply 30W.

Why does it have two SFP slots?

The 2×1000Base-X SFP slots allow dual fiber uplinks: run two separate fiber paths for redundancy, or split camera traffic between copper and fiber so no single link is overloaded. The 2 gigabit RJ45 uplinks stay available for a nearby switch or NVR at the same time.

How far can each camera cable run?

Each copper segment follows the IEEE 802.3 limit of 100m from switch port to camera. For links beyond that, or between buildings, use the 1000Base-X SFP slots with fiber modules on the uplink side instead of stretching copper past specification.

What is the difference between the 96W and 120W versions?

Both share the same layout: 8 gigabit PoE ports, 2 gigabit RJ45 uplinks, 2 SFP slots, 30W max per port. The 96W standard model has no watchdog; the 120W high-power (D) model raises the PoE budget and adds watchdog auto-reset to recover frozen cameras without a site visit.

What devices is it compatible with?

Any device that follows IEEE 802.3af/at: mainstream IP cameras, wireless APs and video intercoms. Detection is automatic — the switch verifies the powered-device signature before applying voltage, so non-PoE equipment on the same ports simply gets a data connection without risk.

How is it installed and powered?

The fanless metal housing measures 240×150×44mm, is IP30 rated and sits on a desktop or mounts to a wall. A built-in DC 52V 2.3A supply runs from AC 176–264V input, compatible with 100–240V adapters, over an operating range of -10°C to +70°C.
