Initial System Setup
The MGC-25 requires basic configuration before you can start running
conferences.
Initial IP Configuration
The system is shipped with a default IP address: 129.254.4.8. Whe never the
system is turned on, the system checks the IP address. If the currently
defined IP address is 129.254.4.8, the system assumes that it has not been
configured and shows the IP Configuration parameters on the LCD window.
You can now enter the IP address allocated to the MCU using the LCD and
the arrow keys.
To configure the IP address of the MGC-25:
1.Open the panel for the LCD as shown:
