WitNet IAS3028G Full-Gigabit Layer 2 Industrial-Grade Ethernet Switch

Product Introduction

The WitNet IAS3028G Industrial Ethernet Switch is a Layer 2 full-gigabit industrial Ethernet switch developed by Beijing Bowayaxun Technology Co., Ltd. It features 28 Gigabit interfaces and offers optional 10/100/1000BASE-T (RJ45) copper ports or 1000BASE-X (SFP) fiber optic interfaces. The switch supports a wide range of Layer 2 software features, including port management, VLANs, multicast, QoS, and Fast Redundant Ring protocols. It also provides multiple management options such as CLI, Telnet, and web-based interfaces, along with SNMP-based network management software. Additionally, the device complies with the IEC61850-3 management protocol.
