Port Description

8 x 10/100/1000Base-T PoE ports (ports 2-8: af/at, max 25.4W; port 1: af/at/bt, max 60W), 2 x 10/100/1000Base-T uplink RJ45 ports, 1 x 1000Base-X SFP uplink slot.
  • 60W PoE++ output on port 1 – powers PTZ cameras & high‑draw APs
  • 250m long‑distance mode via DIP switch (10M, with cable up to Cat5e)
  • One‑key VLAN isolation on ports 1-8 reduces broadcast storms for video
  • Real‑time PoE power usage shown on front digital tube
  • Metal fanless case, built‑in PSU, stable from -20°C to 60°C
  • Optional 6KV common/4KV differential mode surge protection
  • Optional AI watchdog auto‑reboots inactive PoE ports









Why your next surveillance or office network needs this 8 port PoE switch with fiber uplink

If you’ve ever struggled with power cabling for IP cameras or needed to extend a network beyond the usual 100m limit, this switch solves both without extra gear. It’s an unmanaged 8 port PoE switch with fiber uplink – meaning you plug in, it works, and the uplink SFP slot lets you connect to a distant core switch using fiber optics. That’s handy for a warehouse, a multi-floor hotel, or a chain of retail stores where copper runs hit distance walls.

Port 1 pushes up to 60W over PoE++, enough to drive high-power PTZ cameras, Wi-Fi 6 access points, or digital signage. Ports 2 to 8 deliver standard 802.3af/at (up to 25.4W each), covering most IP cameras and VoIP phones. The total PoE budget is 120W – plenty for eight basic cameras or a mix of devices. The switch auto-detects PoE devices, so you won’t fry non-PoE gear.

A DIP switch on the front does two things: flip it to 250m mode and ports 1–8 slow to 10M but reach up to 250 meters over good Cat5e/6 cable – perfect for a far-end camera in a parking lot. Flip it to VLAN mode and those eight ports are isolated from each other (they only talk to the uplink ports 9–11), cutting broadcast traffic and making your video stream more reliable. No configuration, no software – just hardware logic that works.

This 8 port PoE switch with fiber uplink is built in a metal shell with no fan (silent operation), handles -20°C to 60°C, and fits on a desktop or mounts on a wall. It’s designed for IT admins who want a no‑fuss, stable device for small to medium deployments.
