?After-sales service? Electronic products will have various unexplained failures. We provide one-year after-sales service for renewal. Within 1 year from the order, only replacement is not repaired. ?Network cable short-circuit protection mechanism?STEAMEMO PoE switch is stable and has strong anti-interference ability, protect the fault caused by the short circuit of the network port. Short Circuit, over current and over voltage protection. ?Fanless design and Plug & Play?Low power consumption fanless design, all-metal high energy heat conduction tank housing design, natural cooling, compact, elegant design suitable for desktop or wall, plug and play, simple Installation. ?4KV Lightning Protection?STEAMEMO Ethernet PoE switch have professional lightning protection design-up 4KV port and power supply thunder prevents, with two levels of protection design respectively, effectively restrain the power of lightning from cable, which equivalent to give the entire network monitoring system with a security fence. ?Built-in power supply?The power supply is located in the PoE switch body and integrated with the switch. It is simple and light. After connecting to our AC Power Cable, the switch can transmit power to the equipment connected to the switch. ?AI PD Detection?The PoE port will intelligently judge whether the device connected to the port needs power supply. If it is a non-PoE device that does not need power supply, the switch will not supply power to these devices and will not damage the device. ?Isolation Mode?One-Key to VLAN: Ports 1-8 are isolated from each other, It is easy for this 8 ports PoE switch to manage and maintain ,Prevent broadcast storms, Prevent data confusion, improve Lan security and data transmission. ?250 meters Extend function?Turn on the extension switch,extend function extending max power and data transmission distance from 100 meters(330ft) to 250 meters(820ft).which is easy to expand network via ethernet cable to somewhere without power supply but need fix device such as IP Cameras. ?8-port poe switch@100W ?PoE switch with 8*10/100Mbps ports PoE, 2 1000Mbps Uplink port and 1*1.25G SFP port, 8*PoE ports providing up to 30W per port, total PoE budget 100W, 2 gigabit fast ethernet uplink ports for connecting NVR and Internet , etc.. ?Active poe switch with IEEE802.3af/at compliant?STEAMEMO PoE Switches support PoE devices and non-PoE devices, but when connecting passive PoE device or non-PoE device,the switch can only transmit data and cannot power your device, so the connected device needs to be separately powered. Or you can use it with active poe splitter.
