"MAC address authentication" is an authentication method that determines whether to permit or deny communication based on the MAC address information uniquely assigned to each piece of hardware. The client's MAC address information is registered with the RADIUS server as a username and user password. When the client initiates communication, authentication is completed between the authentication switch and the RADIUS server, allowing all devices that perform network communication to be subject to authentication. No specialized software is required for authentication. This feature is suitable for improving the security level of networks with access requests from a large number of unspecified clients. 【Supported Devices】 ■ST13528M ■ST13116M ■ST13512PW・ST13518PW *For more details, please refer to the PDF document or feel free to contact us.

"MAC address entry" registers the client's MAC address information within the switch and determines whether to allow or prohibit communication based on the registered MAC address information. The number of MAC addresses that can be registered is a maximum of two per port. To facilitate the registration of MAC addresses, it is also possible to automatically register the client that initiated data communication first and the client that initiated data communication second. If you want to avoid managing the RADIUS server but still want to manage the permission or prohibition of communication for clients, you can restrict the clients that can connect to the network edge.

The "SYSLOG function" is a standardized client/server communication method for transferring log messages over an IP network. Our products record events that occur internally within the switch. Additionally, through the SYSLOG function, log messages can be sent to an external server, allowing for the recording of access information to the device, whether configuration changes have occurred, results of MAC address authentication, control results of MAC entries, SNMP trap information, and port error counter information. By using it in conjunction with the MAC address authentication function, the status of unauthorized access can also be managed. 【Applicable Devices】 ■ST13528M ■ST13512M ■T13116M ■ST13512PW・ST13518PW *For more details, please refer to the PDF document or feel free to contact us.

The "NTP function" refers to the Network Time Protocol (NTP), which is a function for correcting and synchronizing the system clock. It corrects the system clock by synchronizing with an external time server. If a time server is not used, it is also possible to set the time manually. By using it in conjunction with the SYSLOG function, the occurrence time of events in the output log (correlation with other devices) can be accurately grasped, thereby improving the level of system management. 【Applicable Devices】 ■ST13528M ■ST13512M ■ST13116M ■ST13512PW・ST13518PW *For more details, please refer to the PDF materials or feel free to contact us.

The "Device Self-Monitoring Function (WDT)" is a feature that monitors whether the main devices inside the equipment are operating normally. If an anomaly is detected, the device is automatically reset to recover from the abnormal state. The device self-monitoring function is designed with a fail-safe mechanism that can detect anomalies even when the CPU has stopped. Minor system anomalies that occur in unmanned equipment, such as roadside cameras, are automatically recovered, allowing for labor-saving in equipment maintenance tasks. 【Target Devices】 ■ST13528M ■ST13512M ■ST13520 ■ST13116M ■ST13512PW・ST13518PW ■ST13908M ■ST12500M *For more details, please refer to the PDF document or feel free to contact us.

The "contact input/output function" allows the device to notify external parties of abnormal conditions (internal temperature, internal power supply voltage, and WDT operation) through contact output. By coordinating with warning lights and display boards, it enables visual monitoring of device abnormalities by individuals other than system administrators. With the conversion function between contact signals and Ethernet, it is possible to relay contact input/output over Ethernet, connecting I/O devices between locations several kilometers apart. 【Target Devices】 ■ST13520 ■ST13116M ■ST13908M *For more details, please refer to the PDF materials or feel free to contact us.

The industrial Ethernet switch product 'ST Series', which is equipped with the environmental resistance and high reliability required by social infrastructure systems, features a "High-Speed Path Switching Function (HSS/MHSS)." HSS is our proprietary loop control function. When a path within the loop is severed, it performs a high-speed path switch in less than 500 milliseconds. MHSS is a function that allows multiple HSS loops to be configured within a single device, enabling control for each loop. By switching modes, it is possible to configure MHSS loops under existing L3 switches. 【Target Devices】 ■ST13528M ■ST13512M ■ST13520 ■ST13116M ■ST13512PW・ST13518PW ■ST13908M ■ST12500M *For more details, please refer to the PDF document or feel free to contact us.
