Product Description

MISCOM7028 series Layer 2 switches comply with IEC61850-3 and IEEE1613 industry standards (China State Grid Class A standard), follow the main communication standards in the industrial field, and meet technical issues such as real-time communication and network security. At the same time, this series provides a variety of ways to manage the switch, including accessing the command line interface (CLI) of the switch through HyperTerminal, or managing the switch through the telnet management system, or using the SNMP management software system to manage the switch, and also supports multiple network monitoring protocols: LLDP, SNTPv4, DHCP. At the same time, it provides some common advanced management functions such as MSTP, IGMP, IGMP Snooping, VLAN, GVRP, QoS, port aggregation, port speed limit, broadcast storm suppression, ACL, port mirroring and so on. In terms of device management, it supports FTP/TFTP upgrade, log recording and uploading, and power failure alarm output. In terms of structural installation, you can flexibly choose rack installation or desktop installation. Products are widely used in integrated energy, smart city, rail transit, intelligent transportation, industrial automation and other industrial fields.
