The network-managed industrial switch literally means a switch that can be managed by the network. There are three management methods, which can be managed through the serial port, through the Web, and through the network management software. It provides a terminal-based control port (Console) and a Web-based page. And support multiple network management methods such as Telnet remote login network. Therefore, network administrators can perform local or remote real-time monitoring of the switch's working status and network running status, and manage the working status and working mode of all switch ports in a global view.
The managed industrial Ethernet switches all follow the SNMP protocol (Simple Network Management Protocol), which is a set of network equipment management specifications that comply with international standards. All devices that follow the SNMP protocol can be managed through network management software. You only need to install a set of SNMP network management software on a network management workstation, and you can easily manage the industrial Ethernet switches, routers, servers, etc. on the network through the local area network. It is also an in-band management method through the interface of SNMP network management software.

The General Office of the State Council issued a clear notice on July 30. When government agencies at all levels use fiscal funds for government procurement activities, they must prioritize the procurement of energy-saving products on the premise that the technical and service indicators meet the procurement requirements. For products that meet the requirements such as performance, mandatory procurement is implemented. It clarifies the principles and conditions for compulsory procurement such as energy-saving lamps.
In June, the State Council proposed ten key energy-saving projects in the notice of the comprehensive work plan for energy conservation and emission reduction, including the promotion of 50 million high-efficiency lighting products, and the central state organs took the lead in replacing energy-saving lamps.
Compulsory procurement of energy-saving lamps is clearly specified in the government procurement list.
It is reported that Australia, Canada and California are also considering legislation to ban the production of incandescent lamps. Major European bulb manufacturers have also recommended to the European Commission that the EU issue laws prohibiting the continued production of non-energy-saving light bulbs after 2015 to save energy and reduce greenhouse gas emissions.
In the domestic and international macro environment, the development of energy-saving lamps has become a historical necessity, and the lighting industry will usher in an energy-saving era.
