Temperature: Standard cold storage: -18°C to -25°C. Humidity: When the door opens, cold air meets hot air. You stand at the entrance of a -38°C cold storage, staring at that "industrial-grade" switch you spent 8,000 yuan on. It feels like a block of ice when you touch it. That's an. The operating temperature of a network switch is one of its most fundamental specifications, directly affecting performance, reliability, and service life. When selecting a network switch, many users notice that operating temperature ranges can vary significantly and are often unsure how to choose. In the driverless mining truck dispatch system at an open-pit coal mine in Ordos, Inner Mongolia, during summer when surface temperatures reached 65°C, ordinary switches frequently crashed due to overheating, causing five mining trucks to lose navigation control. Typically, the temperature tolerance range for standard commercial-grade switches is about 0°C to 45°C (32°F to 113°F), while the temperature range expands to approximately -40°C to 85°C (-40°F to 185°F). Unlike regular commercial switches, industrial-grade switches are designed to operate under a much wider range of temperature conditions, often referred to as "extended temperature ranges.
