Elisej Babenko You may want to buy what fits your budget and still be good on features. I would generally recommend on buying an APC UPS. It has good life and pretty good features too. They came in various models, you may want to check out their website. http://www.apc.com Usually, if you are willing to interface the UPS with your Computer, like it should automatically shutdown the computer when there's a power failure, then you may want to buy one with USB support. But I am not sure that you can interface it with FreeBSD. It can be done with Linux and Windows. :) -- Regards, Amit. http://copperskullcprogramming.blogspot.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: How to choose an UPS?
If you are going to interface it with the FreeBSD for automatic shutdown, etc. Look at the port for nut in /usr/ports/sysutils. This supports only serial port models in the stable version but supports USB in the experimental version. I use the stable version and have bought Belkin's that have both USB and serial ports on their units for monitoring. This is in their line for UPS-networking. These are pretty good priced too. -Derek At 01:44 AM 11/28/2006, [EMAIL PROTECTED] wrote: I am going to buy an UPS. What should I know and take into account to choose a proper one?

You should look to the overall capacity, (to make sure it can operate your hardware), and then the runtime... for example, you probably want something larger than 500va on a dual-cpu server loaded with goodies... however a 500va unit is just fine for the average desktop system. My advice, would be to calculate the maximum draw for everything you want on the UPS combined, (ie: 450watt desktop pc, 250watt monitor = 700watts total), and then find a UPS with a suitable runtime for that wattage, ie: decent 1000va should give about 20mins for a 700watt load. Bear in mind, that's at maximum draw and maximum charge on the UPS' battery... so your runtime will vary and almost never maxes at what the box it came in may say ;) Be liberal about it is all, and remember to leave monitor (if any) off when you're not around. Unless of course you're talking about larger (datacenter-oriented) UPS'... in which case, if you're asking this generally - it'd be my advice to you to seek out an electrician. -- Nathan Vidican [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This supports only serial port models in the stable version but supports USB in the experimental version. For APC UPSes, sysutils/apcupsd is probably preferable. It's also under active development, the developers are well-versed in FreeBSD-specific issues, and respond quickly to questions on the mailing list. The FreeBSD port is a little behind the current release, but still works fine for most cases.

Re: How to choose an UPS?
apcupsd rules. Adam is quite responsive (if he's not traveling) with
fixes. USB works for most cases.

Re: How to choose an UPS?
Usually, if you are willing to interface the UPS with your Computer, like it should automatically shutdown the computer when there's a power failure, then you may want to buy one with USB support. But I am not sure that you can interface it with FreeBSD. It can be done with Linux and Windows. :) Check out the port sysutils/apcupsd According to the documentation on the project's website http://www.apcupsd.com, it works with both USB and with a serial cable. I've seen other people on this list reporting that it works with both of those solutions. For a network solution, you can also check the sysutils/nut port which also has a USB driver. More info on the project's website at http://www.networkupstools.org/.
