The operating environment temperature of the RG-N18014 switch ranges between 0 and 50°C. The thermal design must
satisfy the requirement on the device's reliability in the temperature range while ensuring the device's safety and
maintainability. According to the thermal design of the RG-N18014 switch, fans are used to draw air for forced convection
cooling in order to ensure that the device works properly in the specified environment.
