S24G02G2GFI is the flagship of the Atlas PoE line: 24 auto-sensing 802.3af/at Gigabit PoE ports, 2 Gigabit RJ45 uplinks, and 2 Gigabit SFP slots in a 19-inch rack chassis, backed by a 162 Gbps non-blocking switching fabric and a 260W total power budget. It's built to be the one rack unit that covers an entire floor or compound at full gigabit speed -- every port, camera, and AP running at full line rate at the same time, with dual fiber and dual copper uplinks for real backbone redundancy.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
- 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.
- Requires 19-inch rack space and commercial-grade conditions -- this is a rack-mount chassis (not desktop or DIN-rail), rated -10°C to +70°C rather than industrial wide-temperature.
Key Features
- 162 Gbps Non-Blocking Backplane — 162 Gbps switching capacity and 120.528 Mpps forwarding rate mean all 24 PoE ports plus both uplinks can run at full gigabit simultaneously without internal bottlenecking.
- 260W PoE Budget, 30W per Port — Automatic af/at detection across all 24 gigabit ports, sized for a full floor of PTZ and IR cameras.
- Dual Fiber + Dual Copper Uplink Redundancy — 2 Gigabit SFP plus 2 Gigabit RJ45 uplinks give real backbone redundancy -- fiber primary with copper backup, or two independent fiber runs to different equipment rooms.
- One Rack Unit for an Entire Floor or Compound — 24 gigabit PoE ports in a single 19-inch chassis is enough to be the only switch a mid-size building or gated community needs.
- 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.
- Fanless, Watchdog-Protected — Fanless 19-inch metal chassis with watchdog auto-reset, built for unattended rack operation in a comms room.
- No Field Power Run Needed Across 24 Ports — PoE carries power and data together on all 24 ports, cutting electrical costs on large multi-camera rollouts.

Who uses it, where it goes and how to install it
Written for the Atlas S24G02G2GFI from its own specifications: 24 × Gigabit PoE ports (802.3af/at), 260 W budget with up to 30 W per port, 2 × Gigabit RJ45 + 2 × Gigabit SFP uplinks, 162 Gbps switching capacity, fanless 19-inch rack chassis.
Who it is for
- Large floors mixing cameras and Wi-Fi APs — All 24 PoE ports are 10/100/1000 Mbps, so gigabit access points, multi-sensor cameras and access-control panels share one rack unit without a 100 Mbps limit at the port; 260 W is the power ceiling for the whole mix.
- CCTV projects of 17 to 24 cameras — 24 fixed IR cameras at a typical 6 W use 144 W, leaving over 100 W for PTZ cameras or APs; up to 10 PTZ at 25 W fit in the 260 W.
- Sites with a fibre backbone — Two 1000Base-X SFP slots plus 2 Gigabit RJ45 uplinks let the switch sit in a floor or building cabinet and reach the control room over fibre, or feed a second switch.
- Distributors and brands wanting private label — The flagship of the Atlas PoE line, factory-direct: neutral casing ready for your logo, custom port/power options, small batches, and chipset options on a project basis.
Where and how to install
- 19-inch rack, one unit high, with air around it — The chassis is 440 × 170 × 44 mm, 2.6 kg, rack-mount only (no desktop version). It is fanless and IP30, rated -10 °C to +70 °C and 5–95% RH without condensation: keep the rack indoors, leave a free unit or vent panel above and below, and do not stack it directly on a hot NVR.
- Mains power and UPS — Built-in supply (DC 52 V 5 A) with AC 100–240 V input, so it runs directly on 110–127 V or 220–240 V mains. Size the UPS for up to 260 W of PoE plus the NVR and router, so cameras and APs keep running through a short power cut.
- Camera cables: 100 m maximum — The page states the standard 100 m per copper segment and lists no extend mode. Plan every camera and AP within 100 m of solid pure-copper Cat5e/Cat6; for gigabit links use Cat5e or better on all four pairs, and label each run at the patch panel.
- Uplinks: one active path to the same network — Connect the NVR or core switch to one Gigabit RJ45 uplink (copper up to 100 m) or one SFP slot with a 1000Base-X module. The switch has no spanning-tree, so two live uplinks to the same network form a loop; keep the second fibre or copper link unplugged as a spare, or use it for a different network.
- Earthing and surge on outdoor runs — No surge rating is listed for the ports. Fit Ethernet surge protectors near the rack on every cable that goes to an outdoor pole, gate or roof, bond the rack to the building earth and use the earthed plug of the supplied power cord.
PoE budget: how many cameras
The 260 W total, not the 30 W per port, sets the limit: 260 W over 24 ports is about 10.8 W per port on average. 24 fixed cameras fit easily, large PTZ cameras top out at about 10. The S2402G1GFI has the same 24 ports and 260 W with 100 Mbps camera ports and extend mode; the S16G02GI is the 16-port gigabit model with 200 W.
| S24G02G2GFI (this page) | S2402G1GFI | S16G02GI | |
|---|---|---|---|
| PoE ports / uplinks | 24 + 2 RJ45 + 2 SFP | 24 + 2 RJ45 + 1 SFP | 16 + 2 RJ45 + 2 SFP |
| Access port speed | 10/100/1000 Mbps | 10/100 Mbps | 10/100/1000 Mbps |
| PoE budget / max per port | 260 W / 30 W | 260 W / 30 W | 200 W / 30 W |
| 4 MP IR cameras at 6 W | 24 (144 W) | 24 (144 W) | 16 (96 W) |
| Mini PTZ at 13 W | 20 (260 W) | 20 (260 W) | 15 (195 W) |
| IR PTZ at 25 W | 10 (250 W) | 10 (250 W) | 8 (200 W) |
| Extend mode | — (100 m) | 250 m @ 10 Mbps | — |
| Uplink: copper (100 m) / SFP fibre | 2 × GE / 2 × 1000Base-X | 2 × GE / 1 × 1000Base-X | 2 × GE / 2 × 1000Base-X |
| Mounting | 19" rack | 19" rack | Desktop or wall |
| Switching capacity | 162 Gbps | 19.8 Gbps | 48 Gbps |
- Gigabit Wi-Fi APs or more than 100 Mbps per device: the S24G02G2GFI. A Wi-Fi AP that needs up to 30 W counts fully against the 260 W, so add APs to the camera total before ordering.
- Only IP cameras, or one or two cameras beyond 100 m: the S2402G1GFI is enough, since 24 cameras at 8 Mbps use 192 Mbps, and it adds 250 m extend mode.
- 16 gigabit devices or fewer, or no rack on site: the S16G02GI (desktop or wall, 200 W, port isolation).
Camera draws (6 W, 13 W, 25 W) are typical assumptions, not page figures: add up the maximum power from each camera's datasheet, since IR, heaters and PTZ motors raise the draw. Sibling figures come from their own pages on this site.
