Switch 1920s crashs randomly

[ApolloPT]

Hello everyone,

Two months ago, when we put this switch in production site, it started making unexpectedly restarts(aka crashing). In that time we contact HPE support, and they advise us to do a downgrade from PD.02.06 to PD.02.05, and till now we didnt saw any more crashs.

Now it crashed again with the same error, after 2 months.

If I were you (supposing a non defective unit) I would try the latest PD.02.10 Software version, it was released just few days ago. Generally avoid downgrades (if possible).

Note: your issue looks very similar to what was discussed on this thread just few days ago with another user.

[ApolloPT]

Thanks for the advice.

I have read changelogs from that version to old ones, and there is nothing mentioning this issue.

Its a dificult situation, because it can happeans anytime, and we never know if upgrading or downgrading it really fixes the issue or not.

I know what you mean but, sometime, a random issue, previously unknown to development (especially if nobody open a support ticket), can be indirectly fixed by other code changes happened during the normal documented code development (which Release Notes report)...so a newer code can - let me say - accidentally solve what is unkown to most. IMHO give the PD.02.10 a try...if it doesn't fix then open a support case to HPE providing all required info.

I was trying to get that version but no mater what I do, I end always here in this website, where there is an option list, but checking any switch doesnt change or give more options on website:

I tried to get those drivers from seraching in:

Am I searching in the wrong side?

[parnassus]

Hi! I see (same with me)...so...let's try the hard way and circumvent *that* portal by going directly to this URL:

https://h10145.www1.hpe.com/downloads/SoftwareReleases.aspx?ProductNumber=JL381A

Let me know...it should work flawlessly (Note: the HPE OfficeConnect Support portal is not better than the My Networking Portal Product Lookup tool...I generally used the latter to check about 1920S/1920/1950 latest software releases and support.hpe.com portal for documentation about those series).

[ApolloPT]

Yes, I did that, when I discover other thread with one post of yours with one url, so I just made the search through the HTTP request ehehe.

Thanks for the help and the tip panassus!

[parnassus]

Yeah...I literally turn up everywhere ...but...great you fixed!
