Operating temperature

-5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5096 ft.)

NOTE:

When the altitude is between 1800 m (5096 ft.) and 5000 m (16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).

The operating temperature of the switch is -5°C to +45°C (23°F to 113°F) when it uses SFP optical modules with 80 km or longer transmission distances.
