From EtherWAN , this is a DIN-rail mounted Hardened Managed 12-Port 10/100/1000BASE-T(X) + 4-Port 100/1000BASE SFP Ethernet Switch designed to provide flexibility, speed, and reliability to support networks for urban infrastructure, transportation, security, power substations, and other areas where connectivity is crucial. The operating temperature range is -40 to 167°F. The processing types are store-and-forward, auto-negotiation, half-duplex back-pressure and full-duplex flow control, and auto MDI/MDIX. The switch features reverse polarity and overload current protection.
For home use, a simple unmanaged Gigabit switch is all you need to expand your router's ports. Buy a managed switch or a switch with PoE only if you are running security cameras, access points, or complex VLAN setups. Available from $1,860.3.
Basic unmanaged network switches use negligible power and have zero maintenance costs. PoE (Power over Ethernet) and large managed switches use more electricity but are still relatively cheap to run.
Common Failure Modes
Switches are solid-state devices with high reliability. When they fail, it is usually due to lightning strikes/power surges blowing individual ports or the internal power supply dying.

Network switches are extremely reliable solid-state devices. They are usually replaced because networking speed standards outgrow them, rather than due to hardware failure.
