The Quad BRI is expected to have a software version at least as
recent as that of the system to which it is connected. If, upon reboot,
the system detects an older software version on the Quad BRI, it
automatically updates the Quad BRI software. The download is
accompanied by an explanatory message.
Do not turn off your system during the download process.
