Re: SG350 firmware upgrade

Tom.s · ‎03-20-2020

Hello everyone,

I found an SG350-28P in some remote location with quite old firmware 2.4.0.91 and I want to upgrade it to 2.5.0.92. My question is, can I do it in one step? Directly from 2.4.0.91 to 2.5.0.92 or it is better to upgrade to 2.5.0.X first? As the switch is in remote location, I must not brick it. Do you think there will be any issues?

Thanks

Tom

- Check Release Notes for targeted version and look for installation/upgrade guidelines.

I checked, but there is written nothing about this, I just wanted to ask you as a community if you faced any issues :)

- For these type of devices direct upgrade/install is usually no problem (but save the configuration first).

You were right, I went directly for the latest version and there was no issue.

Thank you :)

Hi Tom,

I can see that you have put this question regarding the firmware upgrade.

I would suggest you to upgrade the firmware version one by one on all switches.

Here is the link given below to upgrade the firmware:
