Network Port

• Service Functions > Network Port

This function enables/disables remote connections to the system via telnet, OSGI command shell, and SMB(samba) protocol.

This function can be used when there is a problem that requires developers to access the system or when there is a need for developers to upload applications for a test.

Since enabling those ports can creates a risk of damaging data stored in the device, agreement of the administrator of the customer site is necessary. The user must log in as the administrator to enable/disable the services.
