This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert. This article delves into the intricacies of Layer 2 and Layer 3 switching, shedding light on their functionalities and differences, particularly within the demanding environments of industrial networks. Layer 2 switches are used to connect multiple Local Area Network (LAN) segments together to form an extended LAN. The PT-7528 Series supports Moxa's Noise Guard technology, is compliant with IEC 61850-3, and its EMC immunity exceeds IEEE 1613 Class 2 standards to ensure zero packet loss.
