Overview

S2402G1GFI packs 24 auto-sensing 802.3af/at PoE ports, 2 Gigabit RJ45 uplinks, and 1 Gigabit SFP slot into a 19-inch rack chassis with a 260W total power budget. It's built to be the one PoE switch an installer needs for an entire floor or yard: enough ports and enough power budget to cover a full hotel floor, school building, or warehouse zone from a single equipment rack, with a larger 10K MAC address table sized for the higher device count this port class attracts.

Is This the Right Fit?

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

Multi-Floor HotelsOne 24-port rack switch per floor IDF covers every room-corridor and stairwell camera without daisy-chaining smaller switches.

Schools & Training CampusesA single rack unit in the server room feeds an entire building's classroom and hallway cameras.

Mid-Size Office Towers & Business ParksCentralizes camera and AP wiring for a full floor from one rack-mounted chassis.

Mid-to-Large WarehousesDock doors, aisles, and yard poles on one switch, sized for the device count a full warehouse floor needs.

Community & Compound Perimeter SecurityGate, perimeter fence, and clubhouse cameras run from one rack unit at the security office.

Chain Store & Franchise HeadquartersHQ back-office or a large flagship store standardizes on one 24-port rack switch per site.

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.
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

260W PoE Budget Across 24 Ports — 30W max per port with enough headroom for 24 PTZ/IR cameras or a mixed camera-and-AP deployment without derating.
One Rack Unit, One Floor Covered — 24 access ports plus 2 Gigabit uplinks plus 1 Gigabit SFP mean a single 19-inch chassis can be the only PoE switch an installer needs for an entire hotel floor, school building, or warehouse yard.
Larger 10K MAC Address Table — Sized for the higher device density this 24-port class draws in mixed camera, AP, and intercom projects.
Smart PoE Detection with Per-Port Protection — Auto-sensing 802.3af/at PoE with per-port fault protection -- a single failed cable or shorted device won't take down the other 23 ports.
250 m PoE Extend Mode — Reaches distant gate or perimeter cameras beyond standard Cat5e/6 limits, dropping only that port's link speed to 10 Mbps.
Fanless, Watchdog-Protected — Fanless 19-inch metal chassis with watchdog auto-reset for silent, maintenance-free rack operation.
No Field Power Run Needed — All 24 PoE ports deliver power and data over Cat5e/6, cutting electrical labor across a whole floor's camera rollout.

Who uses it, where it goes and how to install it

Written for the Atlas S2402G1GFI from its own specifications: 24 × 10/100M PoE ports (802.3af/at), 260 W budget with up to 30 W per port, 2 × Gigabit RJ45 + 1 × Gigabit SFP uplink, 250 m extend mode, 19-inch rack chassis.

Who it is for

Projects of 17 to 24 cameras from one rack — A full hotel floor, school building or warehouse zone: 24 PoE ports and 260 W run 24 fixed IR cameras at a typical 6 W (144 W) and still leave over 100 W for PTZ cameras or APs.
Integrators with many PTZ cameras — Any port gives up to 30 W (802.3at), and the 260 W total runs up to 10 PTZ cameras at 25 W, compared with 8 on the 200 W 16-port models.
Compounds and perimeters with long cable runs — Extend mode reaches up to 250 m on a port at 10 Mbps for a gate or fence-pole camera, and the SFP slot links the security office to the main building over fibre.
Distributors and brands wanting private label — An Atlas factory-direct model: neutral casing ready for your logo, custom port/power options, small batches, and chipset options on a project basis; 10 units per carton (reference).

Where and how to install

19-inch rack, one unit high, with air around it — The chassis is 440 × 136.5 × 44 mm and 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 blank space or vent panel above and below it rather than stacking it directly on a hot NVR, and make sure the rack itself is ventilated.
Mains power: AC 100–240 V — The power supply is built in (DC 52 V 5 A) and the input is AC 100–240 V, so it runs directly on 110–127 V or 220–240 V mains with no transformer. Size the UPS for up to 260 W of PoE plus the NVR and router.
Camera cable lengths — Normal mode: up to 100 m of Cat5e/Cat6 per camera. Beyond that, set the port to extend mode for up to 250 m at 10 Mbps. Use solid pure-copper cable and label each run at the patch panel so a port can be traced quickly when 24 cables arrive in one rack.
Uplink to the NVR, one path only — Connect the NVR or core switch to a Gigabit RJ45 uplink (copper up to 100 m), or use the SFP slot with a 1000Base-X module for fibre to another building. The switch is unmanaged with no spanning-tree, so never connect two of its uplinks to the same network: that creates a loop.
Earthing and surge on outdoor runs — No surge rating is listed for the ports. Perimeter and pole cameras are the usual lightning path, so fit Ethernet surge protectors on those runs near the rack, 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 S24G02G2GFI has the same ports and budget with gigabit access ports; the S1602G1GFI is the 16-port, 200 W model.

24 ordinary IP cameras at 8 Mbps use 192 Mbps in total, far below the 1 Gbps uplink, so the S2402G1GFI is enough; choose the S24G02G2GFI only for gigabit APs or devices that need more than 100 Mbps each.
A mix such as 4 PTZ at 25 W (100 W) plus 20 fixed cameras at 6 W (120 W) is 220 W and fits with headroom.
No 19-inch rack on site, or 16 cameras or fewer: the S1602G1GFI comes in a desktop version.

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.

24-Port PoE Switch FAQ — S2402G1GFI

How many cameras can the S2402G1GFI power at the same time?

All 24 PoE ports together. The 260 W full-load budget averages just under 11 W per port, and typical IP cameras draw 4–12 W, so a 24-camera build works with sensible planning. Any single port can push up to 30 W (IEEE 802.3af/at) for a PTZ, and smart detection protects non-PoE gear.

Can one unit cover a whole floor or warehouse zone?

That is the design brief: 24 PoE ports and a 260 W budget from a single 19-inch 1U rack unit, sized for a full hotel floor, school building or warehouse zone. The 10K MAC address table is larger than usual for this class, matching the higher device count, and switching capacity is 19.8 Gbps at 14.73 Mpps.

How do I reach a camera beyond 100 m of cable?

Use PoE Extend mode: the port keeps delivering PoE and data up to 250 m, with that link's speed reduced to 10 Mbps — fine for a single camera stream at a far gate or fence corner. Standard ports run 100 m. Pinout is Mode A, power over the data pairs, per IEEE 802.3af/at.

What uplinks connect it back to the recorder room?

Two 10/100/1000Base-T RJ45 uplinks and one 1000Base-X SFP slot. Copper handles a same-room NVR; the SFP takes a fiber module when the recorder sits in another building past the 100 m copper limit. Star, tree and bus topologies are supported with store-and-forward switching throughout.

What are the build and environmental specs for the rack room?

A fanless 19-inch 1U metal chassis, 440 × 136.5 × 44 mm, 2.6 kg, IP30 rated, with a built-in DC 52 V 5 A supply on AC 100–240 V input. It operates from −10 °C to +70 °C at 5–95 % humidity, carries a watchdog auto-reset, and lists a 50,000-hour MTBF. Ships 10 units per carton for project orders.

Can the S2402G1GFI give 30 W to all 24 ports, for example 24 PTZ cameras?

No. 30 W is the per-port limit, but the whole switch has 260 W, and 24 × 30 W would be 720 W. That is 8 devices at a full 30 W (240 W) or 10 PTZ at 25 W (250 W); across all 24 ports it averages about 10.8 W each. For a large PTZ count, split the PTZ cameras over two switches or mix them with low-power fixed cameras.

Which camera settings work on an S2402G1GFI port in 250 m extend mode?

That port runs at 10 Mbps, so keep the camera's total traffic well under it: H.265, a main stream of about 4 Mbps or less and a small sub-stream. The other 23 ports keep their normal speed. If the camera does not link, set its network port to 10 Mbps full duplex, and use solid-copper Cat5e/Cat6, since 250 m is a best case that depends on the cable and the camera.

Does the S2402G1GFI work with Hikvision, Dahua, Uniview or other camera brands?

Yes, with any camera, AP or intercom that takes standard IEEE 802.3af or 802.3at PoE. The switch detects each device before powering it, uses Mode A (power on the data pairs) and has per-port fault protection, so a shorted cable does not take down the other ports. Passive 12 V or 24 V PoE devices and 802.3bt devices above 30 W are not supported.

Which SFP module do I need for the S2402G1GFI fibre uplink?

A 1000 Mbps (1000Base-X) SFP module; a 100 Mbps module will not link in this gigabit slot. Pick single-mode or multimode to match the installed fibre and use a matching module at the far end (same speed, paired wavelengths for single-fibre BiDi). Modules are not in the box contents, so order them separately or ask us to quote them with the switch.

Can the S2402G1GFI be supplied under our own brand?

Yes. It is an Atlas factory-direct switch: the page offers a neutral casing ready for your logo, custom port/power options, small batches and chipset options on a project basis. Printed boxes or custom packaging are not described on the page, so send us your logo, quantities and packaging needs and we confirm them in the quotation.

S2402G1GFI or S24G02G2GFI: do I need the all-gigabit version?

For cameras, usually not. Both are 24-port, 260 W, 30 W per port, 19-inch rack switches with gigabit uplinks; the S2402G1GFI's camera ports are 100 Mbps, which is far more than a single camera stream, even a 4K one at a typical 8–16 Mbps. Choose the S24G02G2GFI for gigabit Wi-Fi APs or a second SFP slot. Only the S2402G1GFI lists the 250 m extend mode, and its MAC table is 10K against 8K.
