Pluggable AC and DC power modules can be used together in the same 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, bu 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.

Console port

RJ45

The console port is connected to a console

for on-site configuration.

                  Console cable

ETH management port

RJ45

You can connect a switch to a configuration

terminal or network management workstation

through the ETH management port to configure

the switch locally or remotely.

You can choose to download the 

software package

through the ETH management port in 

the BootLoad

menu. File transfer through the ETH management

port is faster than transfer through the console port.
