GE 336A4940DNP5 Series Technical Notes

The GE (General Electric) 336A4940DNP5 series represents a line of managed industrial Ethernet switches engineered for deployment in process-critical environments including chemical plants, oil refineries, nuclear power stations, and heavy manufacturing facilities. These switches are designed to operate within GE's broader DCS and SCADA infrastructure, providing deterministic, high-availability network communication between PLCs, HMIs, historian servers, and field devices. Their ruggedized construction, wide operating temperature tolerance, and support for redundant ring topologies (RSTP/MRP) make them a standard backbone component in brownfield industrial networks worldwide. The series has been widely installed across North American and European process industries since the mid-2000s and remains in active service at thousands of sites globally.
