Airflow direction         Air intake from left and air exhaust from right

Storage temperature [C(F)] –40C to +70C (–40F to +158F)

Long-term operating temperature [C(F)]         -5C to +50C (23F to 122F) at an

altitude of 0-1800 m (0-5905.44 ft.)

Restriction on the operating temperature variation rate [C(F)]                 When the altitude is 1800–5000 m (5906–16404 ft.), the highest operating temperature reduces by 1C (1.8F) every                                                                                                                                         time the altitude increases by 220 m (722 ft.).

Devices cannot start when the temperature is lower than 0C (32F).

The operating temperature ranges from –5C (23F) to +45C (113F) 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 40C (104F).
