Maybe Michal Soltys has some additional insight into these models, but my first guess is that they are old enough (pre-2009) to work with the 'apcsmart' driver, and they should support normal low-battery shutdowns: http://www.networkupstools.org/docs/man/apcsmart.html > If it isn't possible, could > you recommend model(s) on which has this feature? > Does it exist models with which user is able to control the power per > power socket? One way to do power control with your existing UPS is to add a Power Distribution Unit (PDU). NUT supports several: http://www.networkupstools.org/stable-hcl.html?device-type=pdu It's difficult for us to recommend specific UPS models, since it seems like every time we find a good one, the manufacturer changes hardware under the hood (using the same model number), or they change to a new, incompatible proprietary protocol (APC did this in ~2009 with their Microlink protocol). My recommendation is to buy from a distributor with a good return policy. -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
