It's rock-solid.

The stability has been perfect. I don't have any real issues with them except that they recently put out a service bulletin. They're here fixing that issue. That's kind of like a recall on a car. I almost don't want to mention that because it's not that big of a deal, but it's one of the more recent issues that has become something of a problem.

Our Eaton UPSs help with business continuity. I have a reliable system in place that I know that I can trust.

It is very stable. It's what I would expect. We have had hardware issues, but they're not chronic. When there is a problem, it always gets resolved. It is a very stable system but it is also a sacrificial lamb. It's taking a lot of heat from commercial power and absorbing it. There are failures but they are absolutely on par with what you expect.

The solution’s ability to be upgraded online, without bringing our production environment down, is really good. I've been surprised. We have had several upgrade hardware replacements and have not had to take the system down. I would rate the redundancy very good that we have built-in for power modules and batteries. We have been able to do quite a few updates without taking our system offline. The built-in redundancy is very good and has helped us save from having to shut our systems down while we upgrade online.

When upgrading, we are able to increase the power capacity of the existing hardware. You can add up to 20 percent capacity instead of replacing the system. To be able to incrementally add capacity as you need it, this means that you don't have to buy more than you need. They give you incremental steps to add capacity where you need it. 

My impressions of the stability of Eaton UPSs has been good. 

I've installed six Eaton 9395s. Three of them had failures when they were one week old. The good part about that is all three of them happened before we had critical load on them. It does seem like they need to be tested a little bit more at the factory. 

When I did a factory witness test in Raleigh for this last one, the problem was that they were getting fan alarms on the maintenance panels. When I asked about the fan alarms, the factory engineer told me, "Well yeah, that's because they've gone with cheaper fans, and the cheaper fans don't have a high enough speed to keep from having a fan alarm." I said, "Well, this test has failed, and I won't accept this unless you replace all the fans." They did. But the thought of them waiting for a customer to catch that just aggravated me.

I'm a proponent of Eaton. I like their technology, but I think they're trying to cut corners now and they need to stop it.

So far, when it comes to performance and reliability, we've had virtually zero problems with the products. From our perspective, they've just been up and running and we haven't heard from them. They've supplied us with power when needed. So it's a win-win for us.

The UPSs are very stable. 

It has prevented us from having downtime because we have UPSs to get us through blinks and power outages. It prevented us from having downtime with all of our medical record systems and other data systems, which would include our telephone system since it is voice over IP. If we didn't have UPS in place during a downtime incident, it would have crippled our organization pretty quickly. We would have had to go to our downtime procedures, which would have slowed everything down. Most of our clinic visits and other outpatient functions would have been shutdown because they would not have had access to all the electronic medical files. Based on our downtime procedures, for every hour down, it usually takes around three days worth of time to recoup the backlog of information and get it back into the system. Eaton UPSs have saved us a lot of potential headaches.

No, issues at all. Lots of reliability. They're used heavily every day.

The way they're built, they're a really resilient UPS. What happens is that these things are 60kW. There are five 12kW modules. You can lose one of the modules. Depending on your load and what kind of mode you have these in, you can lose up to two of them and things still keep cranking away. Now, what happens when you lose those tools is that you don't have your redundancy. But that's why we have other systems in place in the data center to carry that load. If you're designed right, these things work beautifully.

The stability of the UPS is very good. There have been no issues.

It seems to be pretty stable.

We haven't had any issues with stability.

Eaton UPS is a stable product.

It is a quality product. As far as I know, we have had no failures that I can think of. It has been very stable and reliable.
