| Restriction on the operating temperature variation rate |
When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).
The switch cannot be started when the ambient temperature is lower than 0°C (32°F).
The operating temperature
The operating temperature ranges from -5°C to +45°C (23°F to 113°F) when optical modules with transmission distances greater than or equal to 70 km are used. |
