The Monoprice 8-port Gigabit Ethernet Switch is a professional networking switch that is capable of working within the fastest network systems. The switch conforms to the IEEE802.3, IEEE802.3u, and IEEE820.3ab standards, allowing it to work with 10, 100, and 1000 Mbps networking products. The 8-port design is perfect for use as a terminal switch for a small workgroup or as an intermediate switch to support a small workgroup with a throughput connection to additional switches or hubs.
This small footprint device includes eight RJ-45 LAN jacks and is powered by an included AC adapter. Installation is as simple as plugging the unit into the power adapter and inserting cables into the ports on the back. When using 10BASE-T connections, Cat3 UTP cable is sufficient and when using 100BASE-TX connections Cat5 UTP or STP cable is acceptable. However, when using 1000BASE-T connections, Cat5, Cat5e, Cat6, or Cat7 UTP or STP cable is preferred, with Cat7 STP providing the highest level of reliability and signal integrity.
The switch automatically detects the use of straight (MDI) or crossover (MDIX) cables and switches the connection to whichever is needed for the connected device. Therefore any of the eight ports can be connected to the upstream hub or router and the others connected to downstream PCs, hubs, or other switches.
This switch incorporates several "green" functions, which help save power and save you money! The switch monitors the connectivity of each port and does not send power or signals down the ones that are unconnected (or which have powered off devices attached). It also monitors the length of each cable and reduces the power to shorter cables, while keeping the higher power applied to the longer cable runs. Finally, the switch will go into sleep/standby mode when it detects no connected or powered-on devices. All these measures add up to reduced energy consumption and costs, which means more "green" in your pocket!
With all speeds, connections, and functions automatically configured and supported, there is no manual configuration or setup required. Simply plug it in and start using it right away!

I took it out of the box and plugged it in. It has been working great ever since.
