Can all the information from all UPS models be read via SNMP or do you supply specific software?

mdecamp

@mdecamp and Mike worked for all of them!

I had more hair when I worked for those companies.

@art_of_shred tons! the more feedback we can get the better. we have reviews on CDW as well. we do beta testing, panels, and are always asking for feedback from users. when we get a chance we like to spotlight our users stories with case studies and videos found here: http://switchon.eaton.com/plug/case-studies and eaton.com/pqsuccess

@JaredBusch Yeah, you should be good to go. If you haven't already downloaded the software, give it a try. Just make sure it provides what you need! We love feedback as well! Eaton.com/IntelligentPower

I am a bit late but... welcome!

Where does the name Eaton come from?

JColeKen

@nadnerB They can be read through SNMP or our Intelligent Power Manager software. However, you prefer!

@Reid-Cooper Thanks Reid!

Is EATON going to be at next years MangoCon? Curious to see what you might bring and be able to demo.

@nadnerB A long time ago...in a far away galaxy...

I've been a little caught up with the Gravatar issue and getting vendor accounts set up. But... Welcome!

And to all the Eaton folks in the top page list... all of your accounts are vendor accounts now. In your profile you can go under "Groups" and choose "Vendor" and you will display your vendor tag.

That's a great idea! Inquiring minds want to know.

Welcome everyone!

What is your representation like in the Australia/New Zealand region?

Do you have an office or just minions that sell stuff (Channel partners?)

Using a UPS is a short term option. In some cases services need to be maintained longer -

Are there best practices for deploying a UPS with a generator?

When designing with a backup solution, compatibility between a UPS and Generator is usually one of the biggest issues. It can be complex and confusing.

If the generator isn't sized large enough, it may not be able to hold voltage and frequency within input tolerances when the UPS comes online. The UPS will view the generator as an unstable power source and never come off of battery. The UPS will have a set input voltage and frequency window; if you go outside the window the UPS will go on battery. You can get into a vicious cycle of going on and off of battery until your UPS crashes and your IT load are dropped.

Several reasons why the generator would be an issue:
• The generator is like a car engine. As it maintains RPMs, it maintains frequency. When the UPS transfers from battery to generator power, the engine may slow down a bit. You can compare this to driving a stick shift while stopped at a red light headed uphill. When you dump the clutch, if you aren't giving it enough gas (or if you are driving a pinto) the RPMs are going to drop down.
• Just like in the automotive world, the bigger the engine (generator here) the more it can handle the dumping of the clutch as the UPS comes off of battery. Bigger (aside from your budget number) is better
• Natural Gas is usually the least combustible fuel out there, and generators that run off of NG are slow to respond and may need to be sized larger than propane counterparts. Diesel is best, but usually predominant in the world of 50kW and larger, but it may present a lot more budget and maintenance issues if you don't have a maintenance program or run them weekly, etc.
• When looking at smaller generators (30kW and below) look at the governor. Electronic governors are quick to respond, mechanical governors are not and may add headaches.
The features of the UPS can also impact you configuration. Most single phase UPS products (20kVA and below) will come back online all at once. Larger three phase UPS products will have "current walk-in" and will slowly transition from battery anywhere from 5-60 seconds. As for sizing solutions with generators under 30kVA for single phase UPS applications, I usually lean on the err of caution being a manufacturer. We recommend the same if you are responsible as the decision maker.
• Generator should be sized 2 times the total load (UPS, A/C, an everything else) for NG and mechanical governor
• 1.5 times the load will work if you have a new generator, Propane or Diesel and an electronic governor.
• Any mix from the above puts you somewhere in the middle of 1.5 to 2 times.

The beauty of this forum is that all the good stuff we glean from this will live on in perpetuity, to be searched and referenced... which is a good thing; if we get too many more questions running, I'll need to come back in order to properly digest all the information!
