As networking is a indispensable nowadays, many devices such as IP phone, web camera, security cameras, access points, RFID readers, remote-control devices need to adopt both power line and network line to become inconvenient. Ethernet is a typical deployment and devices like POE interface is becoming a trend. CWG-800 comes with a brilliant design with 8-port web-managed Gigabit Power over Ethernet switch. With all the versatile features like advanced ethernet functions such as DHCP, Tag-VLAN, Trunking, RSTP, IGMP, relocatable HTTP port, the software & its unique PoE function fits any network requirement and is ideal for small or medium size application to offer a low cost solution. CWG-800 supports 5 different classes （0,1,2,3,4） of Powered Device, over current protection and most uniquely, a 3 digit 7-segment LED display showing power consumption of either individual port or whole system. This is a critical function to greatly enhance the system performance and reliability because it provides convenience and security when a new PD is added. Then, user can check from the panel to decide whether and which class of PD can be loaded or not. Reversely, once the PD is removed, the power con dition will be increased to correct values on the panel and the information can also be shown on the web page.
