Overview
The NSW2020-16T2GC-POE-IN is an unmanaged 19-inch rack-mount Fast Ethernet PoE switch with 16 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus two 1000Mbps Combo RJ45/SFP uplinks (G1/SFP1, G2/SFP2), built for machine-room and wiring-closet camera aggregation with independent fiber or copper uplink paths. It delivers a 250 W total PoE budget (30 W max per port, IEEE 802.3af/at, both Mode A (1,2/3,6) and Mode B (4,5/7,8) pinout support) over a 7.2 Gbps switching fabric with 5.36 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 (265 W max). The all-metal 440×195×44 mm 1U chassis (2.07 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.
16-Port Fast Ethernet PoE Bank Feeds a Full 16-Channel NVR16 PoE-enabled ports power and connect a complete 16-channel NVR from a single 1U switch — one device covers a full camera bank without splitting cabling across multiple small switches in the rack.
Two SFP-Ready Combo Uplinks for Independent Fiber and Copper PathsG1/SFP1 and G2/SFP2 are both Combo ports that take an RJ45 copper run or an SFP fiber transceiver — run one uplink over fiber to a distant core switch while the second stays on copper for a local NVR, or fiber both for a redundant dual-homed link, without needing a separate media converter.
Mode A + Mode B PoE Pinout Covers Mixed-Vendor PD CamerasUnlike single-pinout PoE switches, this model powers PDs wired to either Mode A (data pairs 1,2/3,6) or Mode B (spare pairs 4,5/7,8) — useful when a project mixes cameras or PD devices from different vendors without needing to check pinout compatibility port by port.
Priority Ports 1-8 Keep Core Cameras Powered When Demand PeaksPorts 1-8 carry PoE power priority, so entrance, server-room or other critical cameras wired to those ports keep drawing power first if combined demand across all 16 ports approaches the 250 W budget.
VLAN Secure Mode with PD Keepalive for Unattended Equipment RoomsFlip the front-panel switch to VLAN (Secure) mode so downlink ports can only reach the uplink, and let PD keepalive auto-reboot any camera that stops responding — cutting truck rolls to remote server rooms and wiring closets.
EXTEND Mode Pushes a Perimeter Camera to 250 m From the Same RackFlip the same front-panel switch to EXTEND (surveillance mode) to push power and data up to 250 m for a single gate, fence-line or driveway camera — no separate mini switch or repeater needed near the main rack.
Not a good fit if:
- Downlink ports are Fast Ethernet only (10/100Mbps, no Gigabit) — for 4K or multi-stream cameras that need gigabit throughput per port, choose a Gigabit PoE switch; only the two Combo uplinks (G1/SFP1, G2/SFP2) run at 1000Mbps.
- Unmanaged — no Web/CLI/SNMP access or per-port VLAN tagging; 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.
- 250 W total budget can't power all 16 ports at 30 W simultaneously (16×30 W = 480 W ≫ 250 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
- 16 × 100Mbps RJ45 PoE ports (priority ports 1-8) plus two 1000Mbps Combo RJ45/SFP uplinks (G1/SFP1, G2/SFP2)

Talk to an engineer →Who uses it, where it goes and how to install it
Written for the NSW2020-16T2GC-POE-IN from its own datasheet: 16 × 100 Mbps PoE ports, two 1000 Mbps Combo RJ45/SFP uplinks, 250 W PoE budget, 30 W per port, Mode A + Mode B PoE, 1U 19-inch rack body with 1 fan and built-in AC power.
Who it is for
- 16-camera projects that include PTZs — 250 W gives about 15.6 W per port with all 16 in use, so 16 mini PTZs at ~13 W (208 W), or a mix of fixed cameras and larger PTZs, run from one switch. That headroom is the reason to choose it over the 150 W NSW2020-16T2GC-LPOE-IN.
- Campus and multi-building sites — Two 1000 Mbps Combo uplinks mean fibre in from the control room and fibre out to the next building's switch, without a separate media converter.
- Upgrades with mixed-brand cameras — Power is supplied on both Mode A (1,2/3,6) and Mode B (4,5/7,8), so standard 802.3af/at cameras and other PoE devices from an older system can move over without checking pinouts.
- Remote equipment rooms — VLAN (Secure) mode isolates cameras from each other and PD keepalive restarts a camera that stops sending data, which saves trips to a cabinet nobody visits.
Where and how to install
- Rack position and airflow — The 1U chassis is 440 × 190 × 44 mm and 2.07 kg, with 1 internal fan. Keep its vents clear, leave 1U above a hot NVR, and keep the cabinet within 0 °C to 45 °C; a fan also pulls in dust, so clean the vents during maintenance visits.
- Power and UPS — Built-in AC 100–240 V, 50/60 Hz; maximum consumption is 265 W at full PoE load. Size the UPS for this plus the NVR and any router, and put them all on it so cameras do not reboot at every mains blink.
- NVR and PCs on the uplinks — Connect the NVR and viewing PCs to G1/SFP1 or G2/SFP2, not to ports 1–16. The datasheet says that in VLAN and Extend modes the downlink ports only talk to the uplink ports, so a recorder plugged into a PoE port would lose the cameras.
- Uplinks: no loops — Use the two uplinks for two different directions, for example one to the core and one to the next switch. Do not connect both to the same core switch or ring the switches: no spanning-tree protocol is listed, so a loop can flood the network and drop all cameras.
- Cable lengths — Camera runs up to 100 m, or up to 250 m in Extend mode with solid-copper Cat5e/Cat6. Copper uplinks up to 100 m; for longer links use 1000 Mbps SFP fibre modules in the Combo ports.
- Grounding and surge — No surge rating is listed. Earth the rack and the switch chassis, add Ethernet surge protectors on runs from outdoor poles, and use fibre between buildings, which also removes ground-potential differences between them.
PoE budget: this 250 W model next to the 150 W LPOE version
Both versions have the same 16 + 2 ports, modes and Mode A/B PoE. The difference is power: with ordinary 6 W cameras both run all 16 ports (96 W), but with PTZs or heaters this 250 W model keeps going where the 150 W LPOE version runs out. The price of the extra power is 1 fan and up to 265 W consumption instead of fanless and 160 W.

- Pick the NSW2020-16T2GC-POE-IN when the 16 ports include three or more PTZs, cameras with heaters, or when you want room to add devices later: 12 fixed cameras plus 4 PTZs at 25 W (172 W) fit here but not on the LPOE version.
- If all cameras are ordinary fixed models and the switch sits in a quiet office, the fanless NSW2020-16T2GC-LPOE-IN is enough.
- If you only need one fibre uplink and one copper uplink, the NSW2020-16T1GT1GC-POE-IN has the same 250 W budget with one Combo port and one RJ45 Gigabit port.
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. Figures for both columns are from the Uniview datasheets of the two models; PoE-MAX lights above 85% of the budget.
16-Port PoE Switch FAQ — NSW2020-16T2GC-POE-IN
How many cameras can the NSW2020-16T2GC-POE-IN power?
All 16 × 100 Mbps ports source IEEE 802.3af/at PoE from a 250 W budget — roughly 15 W per camera fully loaded, well above the 4–12 W a typical fixed IP camera draws. A single port can supply up to 30 W for PTZ or heated housings, so 16 cameras including a few PTZ is workable.
Why two combo SFP uplinks instead of one?
The two 1000 Mbps Combo ports (G1/SFP1, G2/SFP2) each accept RJ45 copper or an SFP fiber module, giving independent uplink paths. Installers typically run fiber to a remote control room on one and copper to the on-site NVR on the other — no media converters needed on either path.
Can it reboot a frozen camera by itself?
Yes. In VLAN (Secure) mode the PD keepalive function watches each PoE port and automatically power-cycles a camera that stops sending data for a set period — a built-in PoE watchdog. The front slide switch also offers Default mode and EXTEND mode, which reaches cameras up to 250 m away.
Will it power cameras that use different PoE pinouts?
Yes — it supports both Mode A (pins 1,2/3,6) and Mode B (pins 4,5/7,8) to IEEE 802.3af/at. Mixed fleets of cameras from different brands, plus older powered devices tied to one pinout, all negotiate power normally on the same 16 ports, which cuts troubleshooting time on retrofit jobs.
What are the power, cooling and compliance details?
A built-in AC 100–240 V, 50/60 Hz supply powers the 19-inch 1U chassis (440 × 190 × 44 mm, 2.07 kg), with 265 W maximum consumption and one internal fan, operating 0–45 °C. It is NDAA compliant, ports 1–8 hold PoE priority, and the 7.2 Gbps / 5.36 Mpps fabric carries all 16 streams.
Should I buy the NSW2020-16T2GC-POE-IN or the NSW2020-16T2GC-LPOE-IN?
Add up the maximum power of every camera from its datasheet, including night-time IR and any heater. If the total stays under about 127 W, the point where the 150 W LPOE version's PoE-MAX light comes on, the fanless LPOE is enough. Above that, or with several PTZs, take this 250 W POE version. Ports, uplinks, modes and Mode A/B PoE are identical, so the choice is only power, fan and consumption (265 W vs 160 W).
Can I chain several NSW2020-16T2GC-POE-IN switches over fibre, or connect both uplinks for redundancy?
Chaining, yes: fibre comes into G1/SFP1 and leaves from G2/SFP2 to the next switch, and every camera on the chain shares the 1000 Mbps link back to the NVR; 3 switches × 16 cameras × 8 Mbps is 384 Mbps, which fits. Redundancy, no: the datasheet lists no spanning tree or link aggregation, so two links to the same network, or a closed ring, create a loop that can bring the whole network down. Keep the topology a line or a star.
Which SFP modules work in the NSW2020-16T2GC-POE-IN Combo ports?
1000 Mbps (1000BASE-X, IEEE 802.3z) SFP modules; 10G SFP+ modules will not link. Match single-mode or multimode to your fibre and use the matching module at the far end; the module sets the distance. Each Combo port is either SFP or RJ45, not both at the same time. The datasheet does not name approved module models, so send us what is at the other end and we will supply a matching pair.
Are the 100 Mbps camera ports on the NSW2020-16T2GC-POE-IN enough for 4K cameras?
Yes for normal CCTV streams: a 4K camera in H.265 usually stays well under 16 Mbps, a fraction of its 100 Mbps port. All 16 cameras at 16 Mbps add up to 256 Mbps, which the 1000 Mbps uplink carries easily. Only a camera that must stream above 100 Mbps, which is unusual for CCTV, would need a Gigabit PoE port.
My NVR lost all cameras after I set the NSW2020-16T2GC-POE-IN to Extend mode. Why?
In Extend mode, as in VLAN mode, ports 1–16 can only talk to the uplinks G1/SFP1 and G2/SFP2. If the NVR is plugged into a PoE port, move it to G1 or G2. Also remember that Extend applies to the whole switch: use it when at least one camera is beyond 100 m, otherwise stay in Default mode.
