1.1 Introduction
The device is a hardened switch. It provides a high-performance switching engine and large buffer
memory to ensure smooth video stream transmission. With its full-metal and fanless design, the
device has great heat dissipation capabilities on its shell surface, and is able to work in environments
that range from–30 °C (-22 °F) to +65 °C149 °F). With its DIP design, it provides a variety of work
modes that suit different scenarios, including corridors and offices.
