The industrial AI edge gateway features dual network ports supporting IEEE 802.3ad link aggregation, doubling the bandwidth after aggregation for high-speed uploading of AI training data. To ensure uninterrupted aggregation link operation under lightning surges, a common-mode choke (CMZ2012A-900T) is added to the PHY side of each network port, along with a TVS ESDLC3V3D3B. Simultaneously, a PBZ1608E600Z0T ferrite bead is added to the core power supply for the aggregation control software to reduce power supply noise. Actual measured bandwidth after aggregation is 1.8Gbps, with no link jitter during ±2kV surge testing.
