Overview

S16G02GI is Atlas's all-gigabit 16-port PoE switch: 16 auto-sensing 802.3af/at Gigabit PoE ports, 2 Gigabit RJ45 uplinks, and 2 Gigabit SFP slots for fiber redundancy or backhaul, all within a 200W power budget. What sets it apart from the rest of the Atlas PoE line is a one-key port isolation / VLAN mode: switch it on and every PoE port can talk only to the uplink, never to another PoE port, which stops a broadcast or loop storm from one bad camera or miswired patch cable from ever reaching the rest of the network -- a common cause of choppy, freezing video on installer jobs.

Is This the Right Fit?

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

Multi-Floor Hotels & ApartmentsIsolate each floor's cameras from one another so a single faulty camera or cabling loop can't storm the whole building's video feed.

Schools & Campus NetworksDozens of classroom and corridor cameras on one switch; port isolation keeps a student-facing AP or a miswired patch cable from taking down the whole segment.

Office Buildings & Business Park CCTVMany cameras installed independently by different contractors over time; port isolation contains any single misconfigured device.

Mid-Size Warehouses & Logistics YardsDense camera counts and frequent re-cabling raise storm risk; one-key isolation is a fast safety net without a managed-switch learning curve.

Parking Structures & Community Perimeter MonitoringIsolates each pole camera so cable damage or moisture ingress on one run doesn't cascade into flickering video elsewhere.

Retail Chain Head OfficesStore IT staff without networking training get storm protection out of the box, no VLAN configuration required.

Not a good fit if:

Fixed-mode isolation, not full VLAN management -- the one-key mode isolates all PoE ports from each other on an all-or-nothing basis; it does not provide per-port VLAN tagging, spanning-tree, or a web management GUI. Choose a managed switch if the project needs granular VLANs or SNMP.
No ring-network redundancy protocol -- built for star, tree, and bus topologies, not self-healing ring recovery.
-10°C to +70°C is a commercial temperature range, not an industrial wide-temperature rating -- for extreme outdoor cabinets, look at Atlas's industrial DIN-rail line instead.

Key Features

All-Gigabit Access — All 16 access ports run at full 10/100/1000M, so 4K/8MP cameras and Wi-Fi 6 APs never get bottlenecked at the edge the way they would on a 100M port.
One-Key Port Isolation / VLAN Mode — Unique to this model: one switch flip isolates every PoE port from every other PoE port -- devices can only reach the uplink, not each other -- stopping broadcast and loop storms without touching a VLAN config screen.
200W PoE Budget, 30W per Port — Automatic 802.3af/at detection across all 16 gigabit ports, sized for a full run of 16 PTZ or IR cameras.
Dual Uplink Path: Copper + Fiber — 2 Gigabit RJ45 plus 2 Gigabit SFP give a choice of copper or fiber backhaul, or a primary/backup pair to the NVR room.
Fanless, Watchdog-Protected — Fanless metal enclosure with automatic watchdog reset, built to run silently and unattended in a comms closet for years.
No Field Power Run Needed — PoE delivers power and data over the same Cat5e/6 cable, cutting installer labor on every camera drop.
Desktop or Rack-Mount Enclosure — Available in desktop or rack-mount enclosures to match whatever cabinet the installation site already has.

Port isolation / VLAN mode is a one-key toggle on S16G02GI: when enabled, every PoE access port can reach only the 2 uplink ports and cannot reach any other PoE port, blocking broadcast and loop storms at the source. Disable it if the project needs ports to communicate directly with each other.

16-Port Gigabit PoE Switch FAQ — S16G02GI

How many cameras or access points can the S16G02GI feed?

All 16 gigabit PoE ports at once. The 200 W budget averages 12.5 W per port — typical IP cameras draw 4–12 W — with up to 30 W available on any single port (IEEE 802.3af/at) for PTZ cameras or Wi-Fi access points. Smart detection keeps non-PoE devices safe on the same ports.

What does the one-key port isolation actually solve?

Flip it on and every PoE port can talk only to the uplink, never to another PoE port. A broadcast or loop storm from one faulty camera or a miswired patch cable stays trapped on its own port instead of flooding the network — a common cause of choppy, freezing video on installer jobs.

Is the bandwidth really enough for 16 gigabit ports?

Yes: switching capacity is 48 Gbps with a 35.712 Mpps forwarding rate and store-and-forward switching, so all 16 gigabit PoE ports plus the uplinks can carry traffic simultaneously. The 8K MAC table covers camera fleets and office gear alike; flow control follows IEEE 802.3x.

What are my uplink options toward the head-end?

Two gigabit RJ45 uplinks plus two 1000Base-X SFP slots. That allows a fiber backhaul with a second fiber for redundancy, or fiber plus copper mixed. Star, tree and bus topologies are supported, and auto MDI/MDI-X with auto-negotiation removes cable-order worries during installation.

Can it survive a hot, dusty equipment cabinet?

It is built for that: fanless metal housing rated IP30, operating range −10 °C to +70 °C, humidity 5–95 % non-condensing, and a watchdog that auto-resets the switch on lock-up. The 300 × 175 × 46 mm unit mounts on a desktop or wall, runs a built-in DC 52 V 3.85 A supply, and lists a 50,000-hour MTBF.
