UPS Solution

Hi,

I am currently involved in a VOIP rollout project for the company I work with. I am looking for advice on the best UPS solution to use to support multiple switch cabinets jotted around the site. Each UPS should be capable of supporting 3 * 48 Port Cisco POE switch.  Ideally, we would like a UPS located at each cabinet that would kick in automatically once our monthly generator test kicks in. Maintaining 100% uptime of our Phone system is of absolute critical priority during these generator tests and power outages.

Thanks for any advice

I would lean towards using Tripp Lite as we have had good experience with it.  The real question that comes up is how long of a runtime you need as this will affect the number of batteries required.  Also note that under normal circumstances, the number of phones in use will be low.  This means that if you purchase managed PDU, you could get away with a 1000 VA UPS instead of 1500 VA where you could program your PDU to reboot your switches in series (1 minute pause between switch reboots).
His required runtime doesn't need to be more than around a minute as the Author said he just needs the UPS units to power the phones until the generator test kicks in.

I've been using APC for almost 20 years and have been completely satisfied with them.

Hi Guys,

1110W sounds about right so the APC Smart-UPS X 1500VA Rack/Tower LCD 230V looks to be the answer I feel and should comfortably manage the load in each of our cabinets.  Uptime is not important as its only takes a couple  of seconds for generator to kick in.  65%  load is also useful to know.

Thanks again
