Netgear ProSafe FS108 v2

This is a used but still working 10/100Mbps network switch from Netgear, this switch has 8 ports and requires no configuration to use, just plug in an Ethernet cable from your router or another switch and then you can add 7 more computers.

The switch has a metal enclosure rather than a plastic one as it is meant for more professional installations, it also comes with the original power supply that has an inline switch so you can disconnect power to it without having to unplug the power supply.
