16. Updating the STM SatLink VSAT SW
The flash in the STM SatLink VSAT can store two SW images, both the currently used SW and a backup
version in case download of a new SW version fails.
Always use the command
sw upgrade as described in section 16.2 to manually upgrade
the software version of a VSAT since this command automatically deletes old backup
software versions and backs up the current software and the configuration.
Do not use the CLI command
dload to upgrade the software of the VSAT since failure to
delete old backup software version may block future automatic software upgrades.
16.1 Automatic Software Update
The STM SatLink VSAT may be configured for receiving software updates from the DVB-RCS Hub
automatically. Whenever the software upgrade application at the DVB-RCS Hub transmits a new
software image, the software upgrade routine in the STM SatLink VSAT will start receiving the software
image given that the new software image has a newer revision than the current software. When the
software download is completed successfully, the STM SatLink VSAT will restart automatically in order
to activate the new software version.
To automatically receive software upgrades, the STM SatLink VSAT must be configured with the PID,
the multicast IP address, and the UDP port allocated by the system operator for multicast software
upgrade, with software upgrade via multicast enabled, and with the VSAT receiver locked on the forward
link. Issue the CLI command
sw show to examine the automatic software upgrade configuration:
#

Users with privilege level 2 may activate and deactivate the automatic software upgrade routine, and
change the PID, IP address, and UDP port number where the software is received by using the CLI
command
sw mcast.
