Industrial switches play a critical role in complex industrial environments, but their hardware failures are often influenced by multiple factors such as power supply, indoor temperature, humidity, electromagnetic interference, and static electricity. Compared with ordinary switches, industrial switches have higher performance and stronger environmental adaptability. These factors can lead to failures in key. Switches are the silent workhorses of modern networks—routing traffic, connecting endpoints, and managing Layer 2 forwarding with speed and precision. This report summarizes the results of the hardware assessment in the form of a Failure Modes, Effects, and Diagnostic Analysis (FMEDA) of the Series 12 Switch.
