12. Updating the Nera SatLink Terminal SW
The flash in the Nera SatLink Terminal can store two SW images, both the currently used SW and a
backup version in case download of a new SW version fails.
12.1 Automatic software update
The Nera SatLink Terminal may be configured for receiving software updates from the DVB-RCS
gateway automatically. Whenever the software upgrade application at the DVB-RCS gateway transmits a
new software image, the software upgrade routine in the Nera SatLink Terminal 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 Nera SatLink Terminal will restart automatically in
order to activate the new software version.
To automatically receive software upgrades, the Nera SatLink Terminal 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 terminal receiver locked on the
forward link. Issue the CLI command
sw show
to examine the automatic software upgrade
configuration:
# sw show

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
.
Example:
# sw mcast 1 511 224.0.1.59 2001
#
will enable automatic reception of software upgrades on PID 511, IP address 224.0.1.59 and UDP port
number 2001.
