Reset to factory default 

 

“Reset to factory default” allows user to reset controller to factory default setting. 

 

 

Figure 3.8.3.1 

 

Reset to default value, the password is: 1234, and IP address to default DHCP. 

Default IP address: 192.168.10.50 (DHCP) 

Default subnet mask: 255.255.255.0 

Default gateway: 192.168.10.254

Import and export 

 
“Import and export” allows user to save system configuration values: export, and apply all configuration: 

import. For the volume configuration setting, the values are available in export and not available in import 

which can avoid confliction/date-deleting between two controllers. That says if one controller already 
exists valuable data in the disks and user may forget to overwrite it. Use import could return to original 

configuration. If the volume setting was also imported, user’s current data will be overwritten. 

 

 

Figure 3.8.4.1 

 

1.

 

Import: Import all system configurations excluding volume configuration. 

2.

 

Export: Export all configurations to a file. 

 

 

 

 

 

 

 
 

 

 
 

 

Tips

 

Please contact with [email protected] for latest firmware.

 

 

Caution

 

“Import”

 will import all system configurations excluding volume configuration; the current 

configurations will be replaced.
