Airflow direction

Air flows in from the left side and front panel, and exhausts from the right side.

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

-5°C to +45°C (23°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)

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

Not supported

Storage temperature [°C(°F)]

-40°C to +70°C (-40°F to +158°F)

Restriction on the operating temperature variation rate

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).

When the QSFP-100G-ER4 optical module is used, the operating temperature ranges from -5°C to +40°C (23°F to 104°F).
