Long-term operating temperature [°C(°F)]

-5°C to +50°C (23°F to 122°F) 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 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).

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

The operating temperature of the switch is -5°C to +45°C (23°F to 113°F) when 10GE SFP+ optical modules with 40 km or longer transmission distances are used.

Storage temperature [°C(°F)]

-40°C to +70°C (-40°F to +158°F)
