[Nut-upsuser] Control power output via serial connection
Hi, I have two APC UPS models and I am trying to find out if it is possible to cut power down via serial connection in Ubuntu Server 12.04.1 AMD64 system. I have models: APC Back-UPS Pro 650 (BP650SI) APC Back-UPS 650 (BK650MI) I have also APC serial cables 940-0020C and 940-0095B. Is this possible with my current hardware? 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? Tero

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 at gmail

They should work either with usbhid-ups or genericups drivers (depending if they have usb port or not), but I have no first hand experience with them.> I have also APC serial cables 940-0020C and 940-0095B.Both cables are for simple signalling, they differ in details though (I persume one is from BP650SI, the other BK650MI).> > Is this possible with my current hardware?
