Devices cannot start when the temperature is lower than 0°C (32°F). The operating temperature ranges from –5°C (23°F) to +45°C (113°F) when optical modules with transmission distances greater than or equal to 60 km are used. The device does not support dying gasp when the ambient temperature is higher than 40°C (104°F). Long-term operating temperature [°C(°F)] -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.) Storage temperature [°C(°F)] –40°C to +70°C (–40°F to +158°F) Long-term operating relative humidity [RH] 5% RH to 95% RH (non-condensing) Storage altitude [m(ft.)] 0-5000 m (0-16404 ft.) Long-term operating altitude [m(ft.)] 0–5000 m (0–16404 ft.)
