Provides power and data connection for up to 16 PoE network devices. Saves time and money by delivering data and power via existing network cables. 10/100/1000 auto-sensing ports automatically detect optimal network speeds. IEEE 802.3at/af-compliant RJ45 PoE/PoE+ output ports. Power output up to 32 watts per port. Manual PoE extend mode (reduces network speed and extends PoE support to 250 m). Manual VLAN mode (allows ports 1 through 16 to be isolated from each other). PoE power budget of 300 watts. Four RJ45 Gigabit and two SFP uplink ports. Supports IEEE 802.3at and IEEE 802.3af-compliant PoE devices (e.g., wireless access points, VoIP phones, IP cameras). Supports IEEE 802.3at/af detection and short circuit, overload and high-voltage protection. Complies with the IEEE 802.3az (Energy Efficient Ethernet EEE) specification. Green Ethernet power-saving technology deactivates unused ports and adjusts power levels based on the cable length. All RJ45 ports with Auto-MDIX (auto uplink) support. Store and forward switching architecture. IEEE 802.3x flow control for full duplex. Supports up to 8192 MAC address entries, Auto-Learning and Auto-Aging. Cooling fan for ventilation. Three-year warranty.
