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).
