My home network is powered by a Lancom GS-1224 managed gigabit network switch. It still ran the original firmware 1.x that I bought it with 10 years ago, and now I wanted to upgrade it to the latest version.
Unfortunately, the Lancom website did not offer any downloads,
and I had to register at their support portal
so that I could open a support ticket
so that I could receive an e-mail with a link
so that I could view the solution in their web portal
so that I could click on the link to their FTP archive:
ftp://ftp.lancom.de/LANCOM-Archive/LC-GS-1224/
It's LC-GS1224-2.05-Rel.wrp.
