4.2 Alternative update procedures
● Apply USB memory stick while instrument is powered on
The instruments detects the USB memory stick and checks the root directory for
applicable update packages. If found, user is asked if he wants to apply an update
and which version is desired. User data is preserved. This procedure requires
some compatibility between the running and the new software package.
Otherwise the new software is not accepted (Archive corrupted”).
● Apply USB memory stick while instrument is powered off
The previously described firmware update procedure can also be initiated by
applying the USB memory stick while instrument is powered off. In this case the
update procedure is triggered during startup sequence right after the operating
system is ready but before the instruments firmware starts. So this procedure is
recommended if for some reason the instruments firmware is not operational.
User data is preserved.
● Update firmware remotely via LAN
Since firmware version 3.01.203.32 subsequent updates can also be performed
via LAN. This procedure does not require any physical interaction with the
instrument and therefore can be executed without having the instrument on-site.
To initiate the update copy the firmware update file via FTP to /home directory or
via SCP to /home/instrument/update directory. Update starts automatically after
transfer is complete. Please ensure that the required LAN services are enabled in
security settings menu (FTP, SSH and Software Update).
● Update firmware be means of the maintenance system
The R&S®SMB100A is equipped with a maintenance system which does not
depend on the instruments operating system and firmware. It is activated by
pressing the rotary knob right after power on when the instrument indicates “Press
rotary knob for maintenance”. Enter security key if requested (default is ‘123456’),
select “Install Firmware Package” and follow instructions. This procedure
reinitializes the instruments mass memory storage, so user data is irretrievably
lost. After reboot execute SETUP Factory Preset to complete instrument
initialization.
