Does anyone use Eaton 9130 series UPS for anything? I'm curious how
they've worked out for you.
I bought a 700VA model to give it a whirl versus the traditional APC
since the Eaton is an online type with static bypass and also does some
high efficiency thing where it normally stays on bypass, but the first
thing it did on the bench was have the inverter/rectifier or bypass
section catch on fire and destroy itself.

My basic rule is that if the first one I buy catches fire, I don't buy any more.

Was this the 2U rackmount form factor, or the tower?
Either way, I hope that you will pursue this with APC tech support. That's
a pricey piece of gear, and it shouldn't toast itself at any time.
As a side note, how do you call a UPS "online" if it stays on bypass most
of the time, and throws out of "bypass" to go to battery?

Reading the specs, it _is_ 'true online' normally, has a bypass mode if
internal failure detected, or manually commanded. UPS totally disabled
in bypass -- if utility power fails while on bypass, downstream devices
lose power. In bypass, device provides 'passive' filtering of utility
power ONLY.
Hi Seth,
A previous employer we looked at a few UPS.
We used Emerson GXT2/3 3Kva UPSs and they worked a treat.
We also tried the Eaton 9130 and we never had any problems with them, but the SNMP monitoring was only good for telling you if there was a problem, not what the problem was. So we eventually went back to the Emersons.
Reading the users manual... pp 33, "Setting Power Strategy", it
indicates that normal operation is true online (as above) and that you
can change it to "high efficiency" mode, which is not online per se
(default bypass, 10 ms cutover if it detects a fail or spike). So it
has 3 modes; default/normal (online), high efficiency (bypass
w/cutback), and partially failed (bypass only, UPS functions
disabled).
It's a selectable feature. I was probably going to set it to true online
mode, but play with the other mode for curiosity's sake.

We have several 5130 and 9125 models (2kVA rackmount), never given us a
problem in years of service... Well, one network management card that lost
its mind, reset the configuration and went on with life, but the UPS just
chugged along. Biggest plus has been that they don't cook their batteries
like APCs do.

Sorry to say, I've used them and had them eat themselves. They just
die mysteriously and let out lots of smoke when they do. When they do,
however, they leave behind a perfectly good set of batteries. I'd
recommend looking elsewhere... Does Eaton/PowerWare still make the
FerrUPS series? Those were *solid*.

Now *that's* good to know...thanks!
We have quite alot of Eaton UPS's in our network, all sorts of models.
There have been no problems from what I've seen, except when you add water from a broken pipe or bad roof.
We've had the once in a blue moon management card reset as Adrian said but it didn't interrupt our equipment.

Thanks! I've been very disappointed with APC. I had a customer spend thousands on replacement batteries/freight for a Matrix 5000 only to have a $5 cooling fan crap out and no way to get a replacement.<sigh>
Interesting. So far the feedback sounds overwhelmingly negative. Heard
some good points on Emerson (I'm assuming Liebert?). We've had much
better luck overall with them, although a couple of incidents where they
don't care to come back online after they were drained.
We largely use the UPS to survive power glitches without dropping the
network for switch reboot times, we're not after long runs. As such,
the occasional extended outages drain the UPS'es and there are always
the percentage of them that do not come back online and require manual
intervention.
We were formerly a big TrippLite user, but they seem to be incredibly
fault-intolerant with regard to the scenario above (coming back online
after draining), and to a lesser degree, going offline after a power glitch.
Never used an Eaton that I'm aware of however.
Would be interested in other recommendations for remote / IDF / MDF
environment UPS systems to just "keep the stack up" over power glitches.

Just go -48vdc.
None of these pesky UPS problems 
Unfortunately there's a serious lack of PoE switches that are -48.
I do have much larger Eaton units like the 9355 that haven't given me
anything to complain about yet. But they're of a wholly different
classes and I don't really expect one to represent the other. The 9130
that exploded was my first foray into their smaller side, destined to be
a telco room aux unit and replace an APC SmartUPS.

Well, you still have 1/2 the UPS - the inverter section. It's not a silver bullet.
I've had issues and experience with many types of UPSes, including HP (probably OEM'd from someone else), APC, EATON/Powerware, and Liebert/Emerson. I keep coming back to APC. Solid units, and are always slightly 'ahead' in technology. Sure, I've seen each model have failures and even faults (big boom style), but APC provides a solid product and supports their customers the best if you ask me. That being said, a very close second choice would be EATON/Powerware.

Are these UPS units going inside the racks? Would it not be better to do
something in the power room with an inverter on the circuits that feed the
racks, such as a large Outback unit with sufficient battery capacity?

With one device acting as your UPS you'd have only one point of failure
(that may be a plus or minus), only one set of batteries to worry about,
and those inverters are very well made.
They have 120v and 240v units. There are other brands you could use but my
experience with various brands is that Outback is the best in their class.

Note the EATON Press release. Maybe the "burn on the bench" is the way
they get to the California energy reduction Standards? If it isn't
working it isn't using power.
Latest Eaton Thought Leadership White Paper Provides Technical Analysis
of Eaton's Energy Saver System
Eaton today announced the release of its latest white paper,
"Understanding Eaton Energy Saver System." In the paper, George Navarro,
an Eaton technical solutions engineering specialist, explains how
Eaton's Energy Saver System (ESS) enables large uninterruptible power
systems (UPSs) to operate at up to 99 percent efficiency without
sacrificing reliability.
Though ESS is rapidly gaining support in the UPS industry for its
ability to build on the strengths of traditional double-conversion
architectures, many consultants and end users have questions about how
ESS works and what enables it to lower power consumption while
maintaining high levels of availability. In the paper, Navarro answers
these questions by providing in-depth technical information about ESS's
architecture, reliability characteristics, computational infrastructure
and surge suppression attributes.
