0°C to 50°C (32°F to 122°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 45°C (32°F to 113°F) when
it uses SFP optical modules with 80 km or longer transmission distances.
-40°C to +70°C (-40°F to +158°F)
