Tips

Place the switch in a well-ventilated 1U space and keep the side vents clear for airflow. Use Cat5e or Cat6 cabling to take full advantage of Gigabit speeds. Because it's unmanaged, you can simply connect your devices and let the switch negotiate speeds automatically – no software or prior setup needed.
