switch, but power modules that use natural heat dissipation and power 

modules that use air cooling cannot be used together

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)]

-5°C to +50°C (23°F   to 122°F) at an altitude

of 0-1800 m (0-5906 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.).

The device can work for a short period of   time when

the operating temperature is beyond the   normal range,

but the following conditions must be met:

·          The operating   temperature can exceed 45°C (113°F) for a 

           maximum of  96 consecutive hours in a year.

·           The total time   when the operating temperature exceeds 

           45°C(113°F)in a year is less than or equal to 360 hours.

·          The number of times the operating temperature exceeds 

          45°C(113°F) is less than or equal to 15 in one year.

If any of the preceding conditions is not   met, the device

may be damaged or an unknown error may   occur.

Devices cannot start when the temperature   is lower than

0°C(32°F).The maximum transmission  distance of an optical 

module used for short-term   

operation cannot exceed 10 km.

Storage temperature
