Overview
The NSW2020-16T2GC-LPOE-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 as the low-power variant in this switch family, for machine-room and wiring-closet camera aggregation where a smaller PoE budget is enough. It delivers a 150 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 the same 7.2 Gbps switching fabric with 5.36 Mpps forwarding, a 4M bit packet buffer and a 16K MAC address table, cooled passively with zero internal fans and powered from a built-in AC 100–240V supply (160 W max). The all-metal 440×195×44 mm 1U chassis (1.93 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.
Fanless Design Keeps Noise Out of Offices, Retail Counters and Reception AreasZero internal cooling fans mean no moving parts and no fan noise — ideal for switches mounted in open-plan offices, retail point-of-sale counters or reception desks where fan hum on a higher-power sibling model would be noticeable, without giving up any of the same 16-port PoE switching capability.
150 W Budget Sized for Standard Fixed-Lens Cameras, Not Idle Headroom You Pay ForA typical 10/100Mbps fixed IP camera draws around 6–9 W, so 16 ports at 9 W each use 144 W — comfortably inside the 150 W budget without paying for the extra headroom of a higher-power sibling model that a standard-camera deployment never actually uses.
Priority Ports 1-8 Matter More Under a Tighter 150 W CeilingWith less spare budget than a higher-power sibling model, ports 1-8 keep PoE power priority so entrance, corridor or server-room cameras wired to those ports stay powered first if combined draw across all 16 ports approaches the 150 W limit.
Mode A + Mode B PoE Pinout Still Covers Mixed-Vendor PD CamerasThe low-power PoE controller keeps the same dual-pinout support as its higher-power sibling model — Mode A (1,2/3,6) and Mode B (4,5/7,8) — so mixed-vendor cameras from an existing project can move to this switch without a pinout compatibility check port by port.
VLAN Secure Mode with PD Keepalive for Small Branch and Retail SitesFlip 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 — useful for small branch offices or retail stores without local IT staff to reset a frozen camera by hand.
EXTEND Mode Reaches a Single Perimeter Camera to 250 m From a Compact Fanless SwitchFlip the same front-panel switch to EXTEND (surveillance mode) to push power and data up to 250 m for one gate, fence-line or driveway camera — the fanless housing fits into a small wall cabinet near the entrance without needing forced-air clearance.
Not a good fit if:
- 150 W total budget is far tighter than a higher-power sibling model — 16 ports at the 30 W/port max would need 480 W, and even a full set of typical 9 W fixed cameras (144 W) leaves under 6 W of spare headroom across the whole switch; for higher-draw PTZ domes, multi-stream cameras, or projects that need real power headroom on every port, choose a higher-power PoE switch sibling instead (see Related Products below).
- 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.

Talk to an engineer →Who uses it, where it goes and how to install it
Written for the NSW2020-16T2GC-LPOE-IN from its own datasheet: 16 × 100 Mbps PoE ports, two 1000 Mbps Combo RJ45/SFP uplinks, a lower 150 W PoE budget with 30 W per port, fanless 1U 19-inch rack body, built-in AC power.
Who it is for
- 16-camera projects with fixed cameras only — Sixteen 4 MP IR bullets or domes at about 6 W each use 96 W, well inside the 150 W budget. This is the 'L' (low-power) version: you do not pay for the 250 W of the NSW2020-16T2GC-POE-IN if the site has no PTZs.
- Offices, shops and reception areas — With 0 fans it makes no fan noise, so a wall cabinet or rack in an open office, behind a counter or next to a reception desk stays silent.
- Sites with fibre in and fibre out — Both uplinks are 1000 Mbps Combo ports, so one SFP can go back to the control room and the other on to the next building's switch, while the 16 copper ports serve local cameras.
- Small branches without IT staff — VLAN (Secure) mode keeps cameras isolated from each other, and PD keepalive restarts a camera that stops sending data, so nobody has to unplug it by hand.
Where and how to install
- Fanless: give it air — The 440 × 190 × 44 mm, 1.93 kg chassis is cooled only through its metal case. Do not sandwich it tightly between an NVR and a UPS; leave 1U of space above it if possible, and keep the cabinet inside the 0 °C to 45 °C operating range.
- Power and UPS — Built-in AC 100–240 V, 50/60 Hz, maximum consumption 160 W, which is about 100 W less than the 250 W version at full load and easier on a small UPS. Put the switch and the NVR on the same UPS.
- NVR on G1 or G2 — Connect the NVR and the client PC to the Combo uplinks G1/G2, never to ports 1–16. In VLAN and Extend modes the datasheet says downlink ports only talk to the uplinks, so anything plugged into a PoE port loses sight of the cameras.
- Cable lengths — Keep camera runs within 100 m, or up to 250 m in Extend mode with solid-copper Cat5e/Cat6. A copper uplink is 100 m maximum; beyond that put a 1000 Mbps SFP fibre module in G1/SFP1 or G2/SFP2.
- 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 rooftops, and prefer fibre between buildings.
- Heavier loads on ports 1–8 — With only 150 W to share, priority matters: ports 1–8 keep power first when demand nears the limit. Put any PTZ and the most important cameras there.
150 W budget: how many cameras it really powers
150 W shared by 16 ports is about 9.4 W per port on average. That covers 16 ordinary fixed cameras at 6 W (96 W) with room to spare, and even 16 cameras at 9 W (144 W), but at that point the PoE-MAX light is on and there is almost no reserve. Each PTZ eats a big share, so count them before choosing this LPOE version over the 250 W NSW2020-16T2GC-POE-IN.

- Pick the NSW2020-16T2GC-LPOE-IN for up to 16 fixed cameras with no PTZ, or just one or two: 14 × 6 W + 2 × 25 W is 134 W, still under 150 W.
- Choose the 250 W NSW2020-16T2GC-POE-IN instead when there are several PTZs, cameras with heaters, or when you want headroom for later additions; same ports, but it has 1 fan.
- If the site has more than 16 cameras, the 24-port NSW2020-24T2GC-LPOE-IN is the low-power option with the same dual Combo uplinks.
Camera draws of ~6 W (4 MP IR bullet/dome), ~9 W, ~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.
16-Port Low-Power PoE Switch FAQ — NSW2020-16T2GC-LPOE-IN
Is 150 W enough for 16 cameras?
For fixed cameras, usually yes: 150 W across 16 ports averages about 9 W per camera, and typical fixed IP cameras draw 4–12 W. A single port can still deliver up to 30 W (IEEE 802.3af/at) for one heavier device. If you plan many PTZ or IR-heavy cameras, size the load before choosing this variant.
How is it different from the 250 W version of this family?
It is the low-power variant: a 150 W PoE budget instead of 250 W, and it is completely fanless — zero internal fans, so no fan noise and no fan to fail — with 160 W maximum consumption. Ports, 7.2 Gbps fabric, 5.36 Mpps forwarding, 4M bit buffer and 16K MAC table stay the same.
What uplinks do the two combo ports give me?
Two independent 1000 Mbps Combo uplinks (G1/SFP1 and G2/SFP2), each usable as RJ45 copper or as an SFP fiber slot. Typical layouts run fiber to the control room on one and copper to a local NVR on the other, or use both as separate gigabit paths to two recorders.
Which PoE pinouts does it support?
Both: Mode A on pins 1,2/3,6 and Mode B on pins 4,5/7,8, to IEEE 802.3af/at. That removes a common field headache — powered devices that only accept one pinout — so mixed camera brands and older PoE devices all negotiate power on the same 16 ports.
What deployment features come in this 19-inch chassis?
A front slide switch picks Default, VLAN (Secure) or EXTEND (250 m) mode; in VLAN mode PD keepalive auto power-cycles a camera that stops sending data. Power is a built-in AC 100–240 V supply. The 440 × 190 × 44 mm, 1.93 kg unit is NDAA compliant, runs 0–45 °C, priority PoE on ports 1–8.
Can I connect a PTZ camera to the NSW2020-16T2GC-LPOE-IN?
Yes, one or two, as long as each stays within 802.3at (30 W per port) and the total stays under 150 W. Example: 2 PTZs at 25 W plus 14 fixed cameras at 6 W is 134 W; put the PTZs on priority ports 1–8. With three or more PTZs, or any PTZ that needs 802.3bt (above 30 W), choose the 250 W NSW2020-16T2GC-POE-IN or power the PTZ separately.
What happens if the cameras on the NSW2020-16T2GC-LPOE-IN need more than 150 W?
The switch keeps priority ports 1–8 powered first, so cameras on 9–16 are the ones that can drop out. The usual surprise is at night, when IR LEDs switch on and draw more than in daytime tests. Watch the PoE-MAX light: per the datasheet it turns on above 85% of the budget, about 127 W; if it is on in the evening, move a camera to another switch or step up to the 250 W version.
Will the NSW2020-16T2GC-LPOE-IN power passive 24 V PoE devices such as some wireless bridges?
No. The switch follows IEEE 802.3af/at and only turns power on after it detects a standard PoE device, so passive 24 V equipment gets data but no power. Standard PoE cameras of any brand are fine. For a passive device, keep its own injector, or use a model that accepts standard 802.3af/at PoE.
Is a fanless rack switch like the NSW2020-16T2GC-LPOE-IN safe in a hot equipment room?
Yes within its rating: the operating range is 0 °C to 45 °C, and because the budget is 150 W the whole unit draws at most 160 W, so it makes less heat than the 250 W version. The risk is the air around it, not the switch: a closed cabinet in a room without air conditioning can exceed 45 °C in summer. Leave space above it, add a cabinet fan or air conditioning if the room gets hot, and do not stack heavy equipment on top.
After setting the NSW2020-16T2GC-LPOE-IN to VLAN mode, my NVR shows no cameras. What did I do wrong?
Most likely the NVR is plugged into one of ports 1–16. In VLAN mode, and also in Extend mode, those ports can only talk to the uplinks G1/SFP1 and G2/SFP2. Move the NVR cable to G1 or G2 and the cameras come back; switch back to Default mode only if you really need ports 1–16 to talk to each other.
