POE-SWITCH integrates power and data onto one single cabling infrastructure, eliminating the need to have extra power wire. Just connect any network cable between the switch and the device, and the switch will automatically detect the settings of the device and adjust itself accordingly. When the system power is overloaded, it will help protect the system by disabling the POE function of lower priority POE ports to maintain the power to higher priority POE ports. The cost-effective POE-SWITCH provides an ideal solution to most kinds of local area network congestion problems.
