Avaya Partner and UPS Backup Systems

[jjdad]

Hello to all.

This is a informational post about UPS sizing.

I installed a new Avaya Partner R7 system in a 5 slot rack that included two 308 modules and fifteen 18D display phones. There is no voicemail in this system.

The customer wanted a UPS system on the phone system and like many of you, I wondered which size UPS to buy to give the longest run time at the best price.

I installed an APC RS 1300VA LCD 120V system, since that was the largest I could find locally without really spending a lot of money. I bought this one at Circuit City for $160. There is a larger 1500VA unit available for around $210 that will give a bit more run time, but no one in my area had it at the time.

Based on the load display on the front of the UPS, this particular phone system only drew 35-40 watts of power and the estimated run time on the UPS was over two hours.

This was much less power draw and longer run time than I was expecting. Now if the system has voicemail, especially the Partner Voicemail VS System, I'm sure the load would be higher and the up time shorter.


So if you are looking for a UPS system to add to a Partner system. Look into one of these units.

The websites of most (if not all) UPS manufacturers provide some sort of program that allows you to input basic information about the equipment and length of time that the UPS needs to be able to provide power and uses the information to present the best configuration to meet your needs.

If it ain't broke, I haven't fixed it yet.

I work all day in the field and when I come home an look at these posts and specific people post all the time it becomes amusing.

As you said, Based on the load display on the front of the UPS, this particular phone system only drew 35-40 watts of power and the estimated run time on the UPS was over two hours.

That's about right. Incoming calls and incoming traffic will reduce the battery backup. These are switching power supplies and if it sees ringing current it has to work harder. Much harder.

More lights and audible on the incoming to activate or draw on the Cr kt makes things change real fast.

The older 206's had a higher load based junk power supplies.

They were energy robing heat transfer units.

They should have been built with a fan.

One older 206 mods like a baby partner stand alone draws at least 90 watts. Amps is the electrical volume of mis-managed resistance.

If Edison got his way it would be DC and cleaner electricity.

Much harder to work on for the common guy. Almost dangerous.

Imagine if all the cube transformers would be obsolete.

Why do they send power from Quebec Hydro DC? Least resistance and cost. Ac amplification over long distance is a resistor.

This is an inverse relationship.. DC is the most efficient.
