This is a 16 Port Rack-mountable Gigabit Network Switch. One of the great features about this item is the ability to power down idle ports saving up to 40% in power consumption over most other switches.
There are 16 10/100/1000Mbps ports with 32Gbps Switching Capacity and IEEE 802.3x flow control
In larger networking schemes it is important to have a bunch of extra ports available, and so with an extra 16 ports, you will be able to connect your PC's, POE Switches, NVRs, DVRs and other Ethernet Devices.
This switch is also built with a fanless design so there is no external noise.
