Appendix B – Flash Update Procedure
B.1
Updating the SCS1620 Software
The system employs the ability to update the system files by one of several
transfer methods including
scp
(secure copy) and
ftp
(which is inherently
in
secure, but performed by local access by the sysadmin) and a variety of other
update methods. The system software is also completely configurable by the
system administrator, which may involve addition or removal of Unix / Linux
system files to suit a particular application.
B.1.1 Software Download
The SCS1620's operating software can be updated by a downloadable software
update (downloaded from Lightwave's FTP site) which consists of two files: a
tar
file and an
update script
file. The two files must always be used as a matched
set (same version). The update files will affect the data stored on the SCS1620's
FLASH device, however the programmed data will remain intact.
After updating the system software, the system must be rebooted in order to
completely save all of the programming changes.
B.2 Flash
Replacement
Procedure
