Dual antenna software upgrade procedure
B.4 Dual antenna software upgrade procedure
When making a software upgrade of a dual antenna system, it must be done in the
correct order to limit downtime of the VSAT service. It is recommended to do the
upgrade at a location where both antennas have connection to the satellite and are
outside blocking zones. In general a dual antenna system must have the same
software version in both antennas, otherwise a software mismatch warning will be
active on the system.
To make a software upgrade, do as follows:
1. Connect to the Slave BDU web server and upload the new software.
2. Wait for the Slave antenna system to reboot and to have finished its Power On Self-
Test (POST) and having connected to the Master antenna system again. The dual
antenna system might show a warning with software mismatch information.
3. Connect to the Master BDU web server and upload the new software.
4. Wait for the Master antenna system to reboot and finish its Power On Self-Test
(POST).
The dual antenna system should now be fully functional without any errors or
warnings present.
