  • Fanless metal enclosure — desktop and wall mount options

The S402E is a 6-port unmanaged AI PoE switch with 4× 802.3af/at PoE ports (30W each, 60W total), 2× uplink ports, and a built-in AC 100–240V power supply. Featuring AI Watchdog, 300m EXTEND mode on all PoE ports, VLAN isolation, 1.2Gbps switching capacity, and ±4kV surge protection in a fanless metal enclosure, it is designed for small IP camera systems, wireless AP networks, and compact office or retail network deployments.

Ideal For

  • Small IP camera and NVR networks in retail stores, offices, and dormitories
  • Wireless access point PoE power delivery in compact deployments
  • VoIP phone networks requiring reliable uninterrupted PoE
  • Small business LAN switch deployments with long cable runs
  • Plug-and-play installations by non-technical staff or rapid integrators

Deployment Advantages

The built-in 60W AC power supply eliminates the need for external PoE injectors, simplifying installation and reducing component count. The 300m EXTEND mode on Ports 1–4 enables long cable runs for remote cameras or APs at 10Mbps — covering most small-site surveillance needs without additional equipment.

AI Watchdog automatically power-cycles unresponsive PoE devices, keeping cameras and APs online between maintenance visits. VLAN isolation prevents broadcast storms common in camera networks, and the compact fanless metal chassis supports both desktop and wall-mount installation in tight spaces.

Frequently Asked Questions

What is the total PoE power budget of the S402E?
The S402E provides a 60W total PoE power budget with a built-in AC 100–240V power supply. Each of the 4 PoE ports supports up to 30W (802.3at). The built-in PSU eliminates the need for external power adapters or PoE injectors, making it a clean, compact solution for small surveillance or AP installations.
How does the 300m Extend mode work on the S402E?
Extend mode reduces the port speed to 10Mbps to enable PoE power and data transmission over cable runs up to 300 metres on Ports 1–4 — three times the standard 100m limit. This allows camera or AP placements far from the NVR or core switch without signal boosters or additional hardware.
Can VLAN isolation be used on the S402E?
Yes. VLAN isolation segments each PoE port (1–4) from each other while allowing all ports to communicate with the uplink. This prevents broadcast storms in camera networks, improves stability, and provides basic network segmentation without requiring a managed 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.
