The more information technology (IT) and operational technology (OT) are connected, the more attention network infrastructure requires, especially to the switches. Indu-Sol’s PROmesh P20 functions as a distribution layer switch in the Industrial information technology (IIT) level. That product won a 2020 Engineers’ Choice Award in the Network Integration – Ethernet Hardware, Switches category. Courtesy: Indu-Sol GmbH
