SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

We installed a SRT1500RMXLI-NC just yesterday and I observed a couple of these messages in the logs:

These are the most recent entries in the logs. There were two more occurences of this yesterday afternoon. It seems that this internal hardware fault is only occuring for a very short period. What should I do? Is that something to worry about?

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

On my issue, I downgraded the network cards firmware and the problem went away

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

Same with me

 

Downgrading the AP9640 network card from 2.2.0.1  to 2.0.0.5 fixed the issue.

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

I have a couple of SRT 3000s that just started with that error also

 

Critical - UPS: In bypass in response to an internal hardware fault.

 

then one second later

 

Informational - UPS: Return from bypass, internal hardware fault no longer present.

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

A small update: I observed the logs of the last days. And these error messages keep appearing every couple of hours (so 5 -10 per day). This is really annoying as it clutters the event log. Is there anything to do about it?

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

Interesting...

 

This error started after I upgraded the firmware on my PowerChute Network Management Card 3.

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

To add to this I can also confirm that after updating ~10 AP9640s to the 2.2.0.1 firmware and within 24 hours every one of them started throwing "In bypass in response to an internal hardware error.", with a return to normal state within the same second.  As mentioned in thread downgrading back to the 2.0.0.5 firmware has resolved the issue on all 10 devices.

 

Thanks, @exHPguy

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

Thanks, for all the replies. I was hoping to solve my issue, but where do I get the old version of the Firmware? I only seem to find v2.2.0.1 on https://www.apc.com/us/en/download/document/APC_NMC3_SU_2201_EN/ and that's what I have already.

Re: SRT1500RMXLI-NC: In bypass in response to an internal hardware fault.

You may be able to reach out to support for it directly.  I know when I had to bring an old Struxureware install to current they provided me with direct links to some of the step upgrades I'd need that aren't available on the site via links any longer.  In this case I happened to still have my 2.0.0.5 download handy which is how I stepped back.  It'd be nice if they didn't remove previous versions once they mark them "obsolete".  Right here's a pretty clear example of a reason to keep at least one additional version available to download.

As others mentioned already, this solved the problem for me.
