Summary: If you want to manage this product via the network be sure you get the unit with a network management card. The card will eliminate the phone/network surge protection ports. We use these units to backup our switches and has been working well for over a year. No complaints so far.
Summary: Great Smart UPS. Well made and easy to replace the battery. Only negative comment is theat because most new computers do not have a RS-232 (serial) connector, the features offered by the software are obsolete and useless.
Summary: the connection to the server is serial, works for me... but really?
Pros: This unit is exactly what I needed. I had a Active PFC power supply, so wanted to make sure to have a pure sine way UPS. This unit runs my server (Quad core Xeon 3400 series, eight drives, lots of fans), router, two switches, wap and still runs for around 15minutes.
Cons: relatively expensive per VA.. but fit the bill for me... and it's not obnoxiously huge and heavy.
Excerpt: We deployed some of these to use at our switching closets. They have nice configurations like being able to turn off the alarm when it loses power since some of these are near living quarters. The rack mount capability is nice to keep the closet organized. The only thing that I see is that it doesn't have the capability to email messages on certain statuses.
