I chose Egypt because I did not find my country MOROCCO (MMC812), can the problem come from that.
I found in the installation manual officeserv 7030 The base board is equipped with switches SW1 to SW8 with the following configuration:
SW5, SW7, SW8: Reserved for future use (OFF recommended)
SW6: IP address Setting
- On: Default factory setting address
- Off: User setting address
SW1~SW4 The pins set the system's country code
so how can I place the last 4 to have my country MOROCCO
