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.).

Devices cannot start when the temperature is lower than 0°C (32°F).

The operating temperature of the switch is -5°C to +45°C (23°F to 113°F) 

when 10GE SFP+ optical modules with 40 km or longer transmission 

distances are used.

Console 

port

RJ45

The console port is connected to a console

for on-site configuration.

                  Console cable

USB port

USB 2.0 

Type A

The USB port can have a USB flash drive 

connected to upgrade the switch, or transfer 

configuration files or other files. The USB 

port can only connect to a USB flash drive 

that complies with USB 2.0.USB flash drives 

from different vendors differ in model 

compatibility and drivers. If a USB flash 

drive cannot be used, try to replace it with 

another one from a mainstream vendor. 

Switches support a maximum of 128 GB 

USB flash drives.

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 

managementport is faster than transfer 

through the console port.
