Hi, I need archived firmware sx200_fw-1_3_7_18.ros for SG200-50 (EoL). Serial is out of support but I only need the intermediate file to upgrade. Portal rejects the case.

Thanks a lot for sharing the files! However, it looks like the sx200_fw_1.3.7.18.ros - Shortcut.zip is actually a shortcut link pointing to a file on the

Hey @Enes Simnica
Thanks for the file! The SF200-24.zip you shared actually contains the sx200_fw-14115.ros firmware, which is the latest version.
However, I’m specifically looking for the sx200_fw_1.3.7.18.ros file — I need that older version for compatibility testing.
Really appreciate your help!

Hello @Enes Simnica do you by chance have firmware and boot code files for the SG300 series? In particular the in between versions needed in order to upgrade to the latest versions (Boot code 1.3.5.06 and Firmware 1.4.11.5 --- correct me if those are not the most recent releases).

@Enes Simnica do you have the last version of the bootcode for SG200 as well, or is it not needed when updating from 1.3.7.18 to (I have bootcode 1.1.0.6 in at least the switch I successfully updated to firmware 1.3.7.18) to firmware 1.4.11.5 (last ever version) ?

Hi, and thanks for the bit late response. I've found the needed files a while ago and successfully updated my SG200s at that time.
Hopefully this will help other homelab users (or for training purposes, because old hardware still exists at some places) to update their switches. Still.. Too bad Cisco does not provide a file archive for their ancient hardware ("no support", but let at least people get the files an get help from a community that would be much stronger if this happened).
I also downloaded the files you supplied to compare the checksum with those I have (but they will probably match - I have so far not found any different/manipulated/corrupt files of the same versions).

Thank you Zulfan!
I was able to get the files from a reddit user, but thank you for sharing! I'll post that link as well.
