4.5.6.1. Main Memory Clear

•
Service Functions > Main Memory Clear
This function resets the main memory of the system to the factory default setting. It can be used to reset the system to the
initial value when the product is functioning abnormally. All the user configured values return to the default values.
To clear the main memory, users need to select the country of the system locates, and rebooting of the system is required.

•
Service Functions > Hard Disk Maintenance > Hard Disk Check
-
This function checks a bad sector in the hard disk. If a bad sector is found, the system will display an error message
and send an email notification to the system administrator.

4.5.6.3. 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.
