28 Gigabit Ports: Includes 24 Gigabit POE+ ports, 2 Gigabit UpLink, 2 Gigabit SFP. The ethernet ports support 10/100/1000Mbps automatic adaptation. The 2 gigabit uplink can be connected to different networks or devices, such as routers, NVRs, etc. The 2 Gigabit SFP Port can be connected to single-mode or multimode SFP modules, and transmit more distance through optical fiber High POE Power: Maximum support 300W high output power, built-in power supply makes installation easier. Support IEEE 802.3af/at, each port max power supply reached 30W. *Please note: not support passive 24V PoE.* Unmanaged Plug & Play: Support Power Detection function, automatically detect devices, can be compatible with non-POE devices to provide data link. Plug and Play, just plug in the power cord, connect the ethernet cable directly to the device, can be used without configuration. Extend Mode: When turn on, the 17-24 POE port can be extended to 250 meter distances and 10Mbps speed; Simultaneously enable the POE wachdog function to automatically monitor POE devices. the port will be restarted when drops, increasing reliability Widely Used: Small and compact size design. fanless, fiber sfp slot, durable Metal housing. LED indicator lights. Widely used in IP cameras, Wireless Access Point, Computer Networks devices, etc. MokerLink 28 Port Gigabit PoE Switch, 24 Gigabit PoE+ Ports, 2 Gigabit Uplink, 2 Gigabit SFP, 300W IEEE802.3af/at, Metal Rackmount Unmanaged Plug and Play Ethernet Switch
