Operating temperature
0°C to 45°C (32°F to 113°F) at an altitude of 0-1800 m (0-5096 ft.)
NOTE:
When the altitude is 1800-5000 m (5096-16404 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 0°C to 40°C (32°F to 104°F) when it uses GE SFP optical modules with 40 km transmission distances.
