Tom, thank you so much for the information. I’ve been looking at a physical planning guide but I couldn’t find anything specific. I’m going to take a look at the link that you sent me. Do you know if these systems use a 110 or 220 volts plug? Thanks again for the info.

I was able to find this information:

However, the system is connected to a small UPS and they system reboots by it self every now and then. I have notice that they have a lot of devices connected on the same power switch/line. They have the UPS, PCs, Printers and a microwave. I’m trying to put the system by it self on a dedicated power line. The problem that I have is that I’m quite sure if the system should be setup on a 110V or 220V port.
Tom, thanks again for the info.

Equipment such as microwaves and laser printers with large power draws at startup or warmup probably would be better on a different circuit. I’ve had them all together at times in new locations until finding out or figuring out how the circuits route, but rarely without intermittent problems.

I don’t have useful info for you in anything here and I’m not aware of anything beyond the descriptions in the document I linked for you. I’ve never worked directly with a 600 series system, so haven’t collected documents. Maybe when I’m back in the office.

Tom, I’m going to get in touch with the CPU manufacturer. We might have to do something else about this. But I was able to find out that it uses 125V 15A receptacle. I will be recommending that we have an electrician come over and setup a 125v circuit just for the system. I don’t think they completely understand that they cannot have a production system connected to a circuit with all of these devices attach to the circuit. Thanks again for your help.

I had a 9406-600 (2129) for 10 years. When the 9910 UPS was attached, the AS/400 would cycle a UPS test every few weeks. Drove me crazy trying to find out what was doing it. It came to a head when the batteries failed and it would re-IPL. When the battery in the UPS failed, we just switched over to a standard 110/120 outlet which was fed off a UPS that supplied the whole computer centre.

I’ve got a planning guide for this box somewhere. I’ll have a look and send it along if I find it.

Hi Eric, are you saying that we can actually install the system on a regular 110/120 outlet? I always thought that you needed the system to be connected to the UPS!
I will take a look at the back of the system to see if I can plug it into a regular power outlet.

Thanks for the info.

I’ve run *my* little box off a normal outlet for years. Very sturdy boxes, and it copes with most stuff. If it wasn’t made by IBM I wouldnt do so.

BUT – it isn’t a production box. UPS have another major function that’s often disregarded, in smoothing out spikes and glitches in the power supply. Yes the i series power circuits will do so, but I would much rather provide mostly clean power, and do everything to keep the production box happy. providing power when the lines come down is its other high profile job of course but less often used than smoothing – especially if you have heavy indusrty around – every time the rolling mill starts, the power drops as their motors kick in – that sort of thing.
Once had to install a motor generator – huge affair that was just what it said – big motor running off mains coupled to a generator that produced clean power, just to avoid all the spikes and drops – but that was in rural Suffolk – years ago.

Sounds like you need to find the old planning guides and pretend you’re putting it in from scratch with all the stuff we used to think through, then match that ‘ideal’ to what you have and see if you can bring them together a bit..

Enjoy!

I’ve had 3 small 400′s on standard 110v for years. One is for production and one is for development. I have all three on their separate UPS that notify the machine when the power is interrupted. Yes, I have the console on the UPS. Plus the router and other equipment. I have had no problems for 10+ years.

Well, I had to replace a battery or two.

Heads up if your planning on plugging in to “110″ directly. Our facility in Woodside, Queens, NY has 122-127V measured directly at the sockets. We fry UPSs with frightening regularity. PC power supplies less so. And motherboards even less. But our rate is probably a couple thousand percent more than an installation with nominal 110v.

So far my 10 year old AS400 has gone through its original IBM UPS and 2 APC UPSs but it’s hanging on.
