It 's totally plug play and it detects when a device connected
How to operate the device?
The TP-Link TL-SG1005D switch is a faster, inexpensive and reliable way to add more 10/100/1000Mbps Ethernet ports to a network. The TP-Link TL-SG1005D comes with 5 Ethernet ports, any of them can be designated as WAN and the rest will act as LAN ports. It's totally plug & play, and it detects when a device connected to a port is active or inactive, and consequently will put the inactive port idle until needed again, reducing the power consumption to an 80% compared to other switches in the market. It also discovers if the device connected to any of the ports is 10, 100, or 1000 Mbps and acts accordingly.It can be used with any router, or directly with a modem. I'm using it together with theTP-LINK TL-PA511 KIT AV500 Powerline Gigabit Adapter Starter Kit, up to 500Mbpsto provide broadband Internet to all the wired devices in my office, and it's like having a second router without paying the cost of it. Even when all four devices are online the speed is great.
