in the same switch.

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

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).When the   QSFP-100G-ER4 optical 

module is used, the operating temperature ranges from

  -5°C to +40°C (23°F to 104°F).
