Product Overview
The SG821P-V2 8 Port Gigabit Ethernet PoE Switch is a robust and versatile networking solution designed for businesses and homes alike. This 8 port gigabit ethernet poe switch features 8 10/100/1000Base-TX Ethernet ports, 2 10/100/1000Base-T Ethernet ports, and 1 1000Base-X SFP slot for flexible fiber connectivity. Ports 2-8 are IEEE802.3 af/at compliant, delivering up to 25.4W of PoE power per port, while port 1 supports the more powerful IEEE 802.3BT (PoE++) standard, providing up to 60W. With a total power budget of 120W, this switch can handle a variety of PoE devices. Intelligent PoE detection ensures power is supplied only to compatible devices, preventing damage. It also features port isolation and extended transmission capabilities.
Key Features
