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.

Storage temperature

-40°C to +70°C (-40°F to +158°F)

Noise under normal temperature (27°C, sound power)

Noise-free (no fans)

Relative humidity

5% to 95%, noncondensing

Operating altitude

0-5000 m (0-16404 ft.)
