Hi there, I've replaced yesterday my old UPS with a brand new "Eaton Ellipse MAX 600 USBS".
I've choosed the Eaton (previously MGE) both because I've always been extremely satisfied with MGE UPSes of all kinds at work, and because of the involvement of MGE (with Arnaud) in nut development, which made me quite sure that I would have no trouble with an Eaton (MGE) UPS and nut, where my previous old UPS was working OK with old nut versions, but not anymore with recent nut versions. So OK, I went to the Ellipse MAX 600, and have a couple questions / remarks : - This UPS supporting both serial (mge-shut) or USB (usbhid-ups) connections/drivers, is there a choice that is "better" than the other in Linux ? Do both drivers / connection methods give access to the exact same parameters / information on the UPS ? - So far I've choosen "serial" for I assume the serial connection to be simpler and more reliable (?) (doesn't need any access to libusb, doesn't need any filesystem mounted to communicate with UPS...) Well, once done, this works (see http://www.bouissou.net/ups ) but I'm puzzled to see that my new UPS seems unable to display input voltage and that it always displays output voltage as exactly "230.0 V" which makes me think that this is the "set" value and not an actually measured value. upsc command output gives the same result : « output.voltage: 230 » and no "input.voltage" field. Annoying. I was wondering if this shortcoming is due to the nut version I'm using now (2.4.1.-3ubuntu2), due to the Ellipse MAX 600 itself, or possibly due to using the serial connection rather than the USB...? Also, I've tried to set a couple UPS parameters using "upsset.cgi", and I observed the following : - I could change the default "battery.charge.low" parameter from "20" to "30". - But when I tried to change "ups.delay.shutdown" and "ups.delay.start" parameters from their default "0" to "20" and "60" respectively, when I validated this in upsset.cgi, my UPS immediately killed power to the machine (?????) and, when power came back some seconds later, I could see that "ups.delay.shutdown" and "ups.delay.start" still both display "0". So my question is "is this a bug or is this a feature" ? I won't play much with this unless I'm sure, at it seems to kill my server power... :-/ (Besides that, the Ellipse MAX 600 user manual is about non-existent... The thing is supposed to be "line-interactive" and there's no indication in the manual at all about any way to know when power boost or buck features activate or if they even really truly exist... Manual is "2 small pages in 294 languages", too bad. There's more information on the box itself than in the manual :-/ My old UPS had more LEDs and a better manual...)
