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 management method of the network management type industrial switch:
1. Manage through the serial port
The managed industrial Ethernet switch comes with a serial cable for the management of the industrial Ethernet switch. First plug one end of the serial cable into the serial port on the back of the industrial Ethernet switch, and plug the other end into the serial port of an ordinary computer. Then turn on the industrial Ethernet switch and the computer power supply. Use the “super terminal” program that comes with the Windows system to manage serial port data.
First, open the “Hyper Terminal”, after setting the connection parameters, you can interact with the industrial Ethernet switch through the serial cable. This method does not occupy the bandwidth of the industrial Ethernet switch, so it is called “Out of band”.
In this management mode, the industrial Ethernet switch provides a menu-driven console interface or command line interface. You can use the “Tab” key or arrow keys to move through the menus and submenus, press the Enter key to execute the corresponding commands, or use the dedicated industrial Ethernet switch management command set to manage the industrial Ethernet switches. The command sets of industrial Ethernet switches of different brands are different, and even the industrial Ethernet switches of the same brand have different commands. It is more convenient to use menu commands.
2. Manage via Web
The managed industrial Ethernet switch can be managed via Web (web browser), but an IP address must be assigned to the industrial Ethernet switch. This IP address has no other purpose except for the management of industrial Ethernet switches. In the default state, the industrial Ethernet switch does not have an IP address. You must specify an IP address through the serial port or other methods to enable this management mode.
When using a web browser to manage an industrial Ethernet switch, the industrial Ethernet switch is equivalent to a web server, except that the web page is not stored in the hard disk, but in the NVRAM of the industrial Ethernet switch. Program upgrade.When the administrator enters the IP address of the industrial Ethernet switch in the browser, the industrial Ethernet switch is like a server to pass the web page to the computer, and it feels like you are visiting a website. This method occupies the bandwidth of the industrial Ethernet switch, so it is called “in band management”.
If you want to manage the industrial Ethernet switch, just click the corresponding function item in the webpage and change the parameters of the industrial Ethernet switch in the text box or drop-down list. Web management can be carried out on the local area network in this way, so remote management can be realized.
3. Manage through network management software
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.
