Overview
The NSW2020-24T1GT1GC-POE-IN is an unmanaged 19-inch rack-mount Fast Ethernet PoE switch with 24 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus a 1000Mbps RJ45 uplink (G2) and a 1000Mbps Combo RJ45/SFP uplink (G1/SFP1), built for larger machine-room and wiring-closet camera aggregation projects. It delivers a 370 W total PoE budget (30 W max per port, IEEE 802.3af/at, Mode B pinout) over an 8.8 Gbps switching fabric with 6.55 Mpps forwarding, a 4M bit packet buffer and a 16K MAC address table, cooled by a single internal fan and powered from a built-in AC 100–240V supply (390 W max). The all-metal 440×250×44 mm 1U chassis (2.93 kg) runs from 0°C to 45°C and switches between Default (Normal), VLAN (Secure, downlink-to-uplink only, with PD keepalive to reboot unresponsive PoE cameras) and EXTEND (250 m surveillance reach) via a front-panel slide switch — no management software required, NDAA compliant.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
24-Port PoE Bank Aggregates a Full 24-Channel NVR From One 1U Switch24 individually-fed PoE ports mean a single 1U switch can power and cable an entire 24-channel NVR deployment — useful for parking structures, retail chains or warehouse perimeters where splitting cabling across two or three smaller switches would eat rack space and add failure points.
370 W Budget Covers the Realistic Camera Mix Across All 24 PortsAt the mix most sites actually run — a handful of PTZ or IR bullet cameras near 30 W alongside standard fixed cameras under 10 W — the 370 W budget comfortably services all 24 ports; for sites planning every port near the 30 W ceiling, size the load around the 8 priority ports instead (see Not a Good Fit below).
Priority Ports 1-8 Keep Critical Feeds Alive as the Camera Bank GrowsAs more cameras compete for the 370 W pool across 24 ports, ports 1-8 keep PoE power priority — route entrance, loading-dock or server-room cameras there so they are the last to lose power if aggregate demand climbs toward the ceiling.
VLAN Secure Mode with PD Keepalive Scales to Unattended Multi-Building SitesFlip the front-panel switch to VLAN (Secure) so all 24 downlink ports can reach only the uplink, and let PD keepalive auto-reboot any of the larger camera count that stops responding — cutting truck rolls as both the number of remote sites and cameras per site grow.
EXTEND Mode Still Reaches a 250 m Perimeter Camera From a High-Density RackThe same front-panel switch flips to EXTEND (surveillance mode) for up to 250 m of reach on a single port, so one high-port-count switch can anchor both a dense indoor camera bank and a distant gate or fence-line camera without a second small switch nearby.
Combo Uplink Bridges to a Fiber Core Switch Across a Larger CampusThe G1/SFP1 Combo port takes either an RJ45 copper run or an SFP fiber transceiver, so a high-port-count switch like this one can still uplink over fiber to a campus core switch spanning multiple buildings, while the dedicated G2 RJ45 port stays free for a local NVR — and the whole 24-port bank still fits a single 1U slot at 440×250×44 mm (2.93 kg).
Not a good fit if:
- Downlink ports are Fast Ethernet only (10/100Mbps, no Gigabit) across all 24 ports — for 4K or multi-stream cameras that need gigabit throughput per port, choose a Gigabit PoE switch; only the two uplinks (G2, G1/SFP1) run at 1000Mbps.
- Unmanaged — no Web/CLI/SNMP access or per-port VLAN tagging, even with 24 ports to control; the front-panel switch offers only Default/VLAN/EXTEND positions, not granular configuration; choose a managed switch if you need remote monitoring or individual port control across a large camera bank.
- 370 W total budget can't power all 24 ports at 30 W simultaneously (24×30 W = 720 W ≫ 370 W) — plan camera load around the 8 priority ports, and note this model is 802.3af/at only, so 802.3bt high-power PTZ domes (60–90 W) need a bt-capable switch or injector.
Key Features
- 24 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus a 1000Mbps RJ45 uplink (G2) and a 1000Mbps Combo RJ45/SFP uplink (G1/SFP1)
- 370 W total PoE budget, up to 30 W per port, IEEE 802.3af/at, Mode B pinout (4/5+, 7/8-)
- Ports 1-8 hold PoE power priority under budget contention
- Three working modes via front-panel slide switch: Default (Normal), VLAN (Secure, downlink-to-uplink only), EXTEND (250 m surveillance reach)
- VLAN (Secure) mode includes PD keepalive: automatically power-cycles an unresponsive PoE camera when it stops sending data
- IEEE 802.3x flow control, port traffic control and packet buffer optimization for smoother multi-camera streaming
- All-metal 440×250×44 mm 1U rack chassis with a single internal cooling fan, NDAA compliant

Talk to an engineer →Who uses it, where it goes and how to install it
Written for the NSW2020-24T1GT1GC-POE-IN from its own datasheet: 24 × 100 Mbps PoE ports, one 1000 Mbps RJ45 uplink plus one 1000 Mbps Combo RJ45/SFP uplink, 370 W PoE budget, 30 W per port, 8.8 Gbps, 1U 19-inch rack body with 1 fan and built-in AC power.
Who it is for
- Projects of 17–24 cameras — Parking garages, supermarkets, factories and hotels that outgrow 16 ports: one 1U switch with 24 PoE ports replaces a 16-port plus an 8-port switch, with fewer power cords and one less cascade link.
- Sites with a mix of fixed cameras and PTZs — 370 W is about 15.4 W per port with all 24 in use, so 18 fixed cameras plus 6 PTZs at 25 W (258 W) still leave over 100 W of reserve.
- Campuses with a fibre backbone — The G1/SFP1 Combo port takes an SFP module to a core switch in another building, while the separate G2 RJ45 Gigabit port serves a local NVR or a second recorder.
- Unattended or multi-site installations — With 24 cameras per switch a frozen camera is more likely; in VLAN (Secure) mode, PD keepalive power-cycles a camera that stops sending data, and the cameras are isolated from each other.
Where and how to install
- Rack depth and position — The 1U chassis is 440 × 250 × 44 mm and 2.93 kg, deeper than the 16-port models, so check the cabinet depth and the space for cables at the back before ordering a shallow wall cabinet. Mount it next to the patch panel so the 24 camera patch cords stay short.
- Heat and airflow — It has 1 internal fan and can draw up to 390 W, much of which ends up as heat in the cabinet. Keep the vents clear, leave 1U free between it and a hot NVR, and add a cabinet fan or room air conditioning to stay within 0 °C to 45 °C.
- Power and UPS — Built-in AC 100–240 V, 50/60 Hz. Size the UPS for up to 390 W from this switch alone, plus the NVR and router; on a small UPS a full 24-camera load shortens backup time considerably.
- Recorders on G1/G2 only — Connect NVRs and viewing PCs to G2 or G1, not to ports 1–24. The datasheet says that in VLAN and Extend modes downlink ports only talk to the uplinks, so anything on a PoE port loses the cameras.
- Cable lengths, grounding and surge — Camera runs up to 100 m, or 250 m in Extend mode with solid-copper Cat5e/Cat6; copper uplinks up to 100 m, fibre beyond. No surge rating is listed, so earth the rack, add Ethernet surge protectors on outdoor runs, and use fibre between buildings.
- Plan ports 1–8 — Only ports 1–8 have PoE priority, out of 24. Put PTZs, entrances and cash desks there, label the patch panel, and keep the less important cameras on 9–24.
PoE budget: how many cameras it really powers
370 W across 24 ports is about 15.4 W per port. That runs 24 fixed cameras (144 W) or even 24 mini PTZs (312 W). The limit only appears with many full-power devices: 30 W per port on 12 ports already uses 360 W, so with more than about 12 large PTZs, split them across two switches.

- Pick the NSW2020-24T1GT1GC-POE-IN for 17–24 cameras on one or two NVRs, including up to about 12 PTZs at the full 30 W.
- For 16 cameras or fewer, the NSW2020-16T1GT1GC-POE-IN has the same uplink layout in a shorter chassis.
- If all 24 are ordinary fixed cameras (~144 W) and you want lower consumption, compare the NSW2020-24T2GC-LPOE-IN; for two fibre uplinks, the NSW2020-24T2GC-POE-IN.
Camera draws of ~6 W (4 MP IR bullet/dome), ~13 W (mini PTZ) and 25 W (larger PTZ) are typical assumptions; check each camera's datasheet. Budget, per-port, distance and PoE-MAX thresholds are from the Uniview datasheet.
24-Port PoE Switch FAQ — NSW2020-24T1GT1GC-POE-IN
How many cameras can the NSW2020-24T1GT1GC-POE-IN power?
All 24 × 100 Mbps ports are IEEE 802.3af/at PoE sharing a 370 W budget — about 15 W per camera with all twenty-four loaded, while typical fixed IP cameras draw 4–12 W. Any port can deliver up to 30 W, so a full 24-camera deployment with several PTZ units still fits the budget.
How do I uplink 24 camera streams without a bottleneck?
Use the two gigabit uplinks: a 1000 Mbps RJ45 port (G2) and a 1000 Mbps Combo RJ45/SFP port (G1/SFP1) for fiber. Twenty-four camera streams at a few Mbps each fit inside one gigabit path; the 8.8 Gbps fabric with 6.55 Mpps forwarding and 4M bit buffer keeps the backplane clear.
What do the working modes and PD keepalive add on site?
A front slide switch selects Default, VLAN (Secure) or EXTEND mode. EXTEND pushes data and PoE power up to 250 m for far cameras. In VLAN mode, PD keepalive automatically power-cycles any camera that stops sending data for a set period, restoring frozen cameras without a site visit.
What should I plan for power and rack space?
It has a built-in AC 100–240 V, 50/60 Hz supply and draws up to 390 W at full PoE load, cooled by one internal fan. The 19-inch chassis is 440 × 250 × 44 mm (1U) and weighs 2.93 kg, rated 0–45 °C at 10–90% non-condensing humidity — plan one rack unit and about 390 W of AC capacity.
Which ports keep power first, and is it NDAA compliant?
Ports 1–8 hold PoE power priority, so connect entrance, perimeter or other critical cameras there; the PoE-MAX indicator flags when the 370 W budget nears its ceiling. PoE pinout is Mode B (4/5 positive, 7/8 negative). The switch is NDAA compliant, with a 16K MAC table for larger camera networks.
Will the NSW2020-24T1GT1GC-POE-IN power Hikvision, Dahua or other non-Uniview cameras?
Yes, any standard IEEE 802.3af/at PoE camera, up to 30 W per port. This model sends power on Mode B (pairs 4/5 and 7/8); standard cameras accept power on either pair set, so this only matters for non-standard devices that take power on the data pairs alone. It will not power passive 12 V or 24 V PoE gear; if an older system has such devices, keep their injectors or ask us about the NSW2020-24T2GC-POE-IN, whose datasheet lists Mode A and Mode B.
Can I connect two NVRs to the NSW2020-24T1GT1GC-POE-IN, for example two 16-channel recorders for 24 cameras?
Yes. Put one NVR on G2 and the other on G1 (RJ45 or, through an SFP, on fibre); all ports, including the downlinks in VLAN or Extend mode, can reach both uplinks. Then add the cameras to each NVR by IP address, for example 12 to each. Give every camera a fixed IP address in one subnet first, so the NVRs do not fight over them.
What SFP module fits the G1/SFP1 port of the NSW2020-24T1GT1GC-POE-IN?
A 1000 Mbps SFP (1000BASE-X, IEEE 802.3z); a 10G SFP+ module will not link. Choose single-mode or multimode to match the fibre, with the matching module at the far end; the module decides the distance. G1 is a Combo port, so it is either the SFP or the RJ45 socket, not both. The datasheet names no approved modules, so tell us the far-end device and we will supply a matching pair.
Is the fan in the NSW2020-24T1GT1GC-POE-IN noisy enough to matter in an office?
It has 1 internal fan and the datasheet gives no noise figure, so plan it for a closed rack, a server room or a back office rather than an open desk area. The fan is needed: at full load the switch can draw 390 W. If the switch must sit in a quiet room and your cameras are ordinary fixed models, compare the low-power NSW2020-24T2GC-LPOE-IN.
When does the PoE-MAX light on the NSW2020-24T1GT1GC-POE-IN come on, and what should I do?
Per the datasheet it is off below 80% of the 370 W budget and steady on above 85%, about 314 W. Check it at night, when IR LEDs and heaters add load. If it is on, the switch is close to the limit and ports 9–24 will be the first to lose power, because only 1–8 have priority; move one or two PTZs to another switch.
