8 port PoE+ Switch


  • L2+ Managed features provide easier manageability, robust security and QoS
  • Built in Device Management System (DMS) DHCP Server
  • IPv4/IPv6 L3 static route
  • PoE Port configuration and scheduling
  • 802.3at high power PoE plus standard
  • IEEE 802.3az EEE Energy Efficient Ethernet standard for green Ethernet.
  • Compatible with both Fiber and Copper connections.


The S81 is a next generation L2 Managed PoE switch offering a full suite of L2 features, additional RJ45/SFP uplink connections, better PoE functionality and usability including advanced L3 features such as Static Route. This switch is made for megapixel IP Camera installations using high performance Gigabit Power-over-Ethernet (PoE).

The S81 delivers 8 (10M/100M/1G) RJ45/PoE/PoE+ ports plus 2 RJ45 SFP combo ports and one RJ45 console port. All the RJ45 ports support automatic MDI/MDI-X operation, auto-negotiation and IEEE 802.3x auto-negotiation of flow control, so the optimum data rate and transmission can be selected automatically.

The S81 performs a wire-speed, non-blocking switching fabric. This allows wire-speed transport of multiple packets at low latency on all ports simultaneously. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

This switch uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.
