Overview
- 16× full-Gigabit PoE ports (802.3af/at) — up to 30W per port, 300W total budget
- 2× Gigabit RJ45 uplinks + 1× Gigabit SFP fiber slot for backhaul
- PoE Watchdog auto-reboots unresponsive cameras and APs (Ports 1–16)
- AI Extend mode — 250m long-distance PoE on Ports 1–8
- Port VLAN isolation via DIP switch to suppress broadcast storms
- Built-in AC 100~240V power supply — no external power bricks needed
- 52Gbps switching capacity with 8K MAC address table
- 4kV surge protection, fanless steel chassis — desktop or 1U rack mount
The S1621G is a 19-port unmanaged smart Gigabit PoE switch with 16× full-Gigabit 802.3af/at PoE ports (30W each, 300W total), 2× Gigabit RJ45 uplinks, and 1× Gigabit SFP fiber slot, powered by a built-in AC 100–240V supply. With PoE Watchdog auto-recovery across all 16 ports, 250m EXTEND mode on Ports 1–8, port VLAN isolation, a 52Gbps switching fabric, and 4kV surge protection in a fanless 1U steel chassis, it is built for mid-size IP camera systems and multi-AP networks in hotels, campuses, and enterprises.
Ideal For
- Mid-size IP camera and NVR networks in hotels, campuses, and factories
- Multi-floor wireless access point PoE power delivery
- Surveillance and network cabinets requiring 1U rack mounting
- Deployments needing a Gigabit fiber (SFP) uplink to a core switch
- Growing small-business LANs consolidating onto a single PoE switch
Deployment Advantages
The built-in 300W AC power supply powers a full 16-port camera or AP deployment without external injectors, while the 1U fanless steel chassis mounts cleanly in a 19-inch rack. Two Gigabit RJ45 uplinks plus a Gigabit SFP slot provide copper or fiber backhaul, keeping aggregated camera traffic congestion-free.
PoE Watchdog auto-recovery covers all 16 ports, power-cycling devices that stop responding so unmanned sites stay online. The 250m EXTEND mode on Ports 1–8 reaches remote cameras and APs, and VLAN isolation suppresses the broadcast storms common in dense camera networks.

Frequently Asked Questions
What is the total PoE power budget of the S1621G?
The S1621G delivers a 300W total PoE power budget from a built-in AC 100–240V supply across its 16 PoE ports, each supporting up to 30W (802.3at). That comfortably powers 16 standard cameras or APs, or a smaller number of high-draw PTZ cameras, without any external injectors.
Can the S1621G be rack-mounted?
Yes. The S1621G uses a 1U 310×205×44mm steel chassis and supports both desktop placement and standard 19-inch rack mounting, making it a clean fit for surveillance cabinets and network racks. It is fanless for silent, dust-resistant operation.
Are all ports on the S1621G full Gigabit?
Yes. All 16 PoE ports are 10/100/1000Mbps, plus 2 Gigabit RJ45 uplinks and a Gigabit SFP slot — every port is Gigabit-capable. This suits Gigabit IP cameras, Wi-Fi 6 access points, and NVR backhaul that need full 1000Mbps throughput across the whole switch.
Is OEM/ODM customization available for this product?
Yes. MossLink offers full OEM and ODM services for this product, including custom firmware features, hardware modifications, enclosure branding, and private-label packaging. Minimum order quantities apply. Contact us to discuss your project requirements.
