parisc,

Just a quick flitting question that has been in
the back of my mind. When working with an A500
that I have, during a GSP powerdown using "PC",
I get the following error:

************* SYSTEM ALERT **************
SYSTEM NAME: firin

Is this bad for my hardware :} It was ever so nice when I was kernel hacking and I could remotely control the box's power. However, after such an error I'm told that:

The system did not respond to the Power-On command. Turn the system power switch Off and On again to reset the system.

Which means I need to be there physically :(
Any help on the matter would be much appreciated.

this would suggest your site has a voltage regulation problem. you might get out a DVM and see if that's a persistent problem.

I'd think yes. normally the power supplies are designed to handle something like 5-10% input power variation.

I'd unplug the power too just to be sure it's really reset.

By 'site' do you mean 'external AC'?

I had assumed that the issue dealt with the internal switching supply doing the damage.

I shall put the system behind a better UPS and see if the problem goes away.

Good point.

Yes, the message indicated that the problem was with a DC supply voltage. If it's internal, this could damage the circuits in the system. CPU chips normally have very tight voltage requirements for proper operation. I would check the manual to see what is recommended when this error occurs. You measure the voltages on an unused drive connector, etc.

hmm...you might be right.

I'd still measure UPS output just to rule that out.
(Ie something easy to do and something I expect the HW to monitor).
