Re: [SLE] How to make UPS working

As far as I know, the cable that comes with the smart UPSs should work under linux, but I don't know for sure, I've never used one. As for the Back-ups office, it's a 'dumb' UPS, if that, (I didn't even know you could plug a cable into those) so a different cable is probably needed if it will work at all.

If you look at APC's site, the should tell you what cable you need for the Smart-UPS 700 to run under Unix, if that's the cable you have, then your good to go. If you can't find the info there, go download and install apcupsd ( ;)

Also, read the docs at along with the readmes, etc., in the package, that should give you some more info.

Hi nick, I'm runninging linux as a trial on a new server here at work, hopely to take the place of our old novell 3.2 server, I have a smart ups 700 with that cable that comes with it, do now know the number for it. What do I need to get it so the ups is seen by linux an will shutdown the machine if it needs to. I'm running suse 7.2. thanks. Not sure If i will need to aquire another cable or now. also have linux on an old pen 166 with an apc back-ups office 500 va ups. the cable that came with it is a 940-0119a guess that is the wrong cable for linux to see it. thanks for any info you can pass on.

I forgot to add that the Back-UPS UPSs are 'dumb' so a smart cable won't do you any good, unless you have a smart UPS (Back-UPS pro, Smart-UPS, etc . . . ).

Yah, that one only works for Windows (no clue why) . . . I called or emailed APC and told them that the only reason I bought theirs over tripplite was that the APC was on sale for $30 less, and APC was asking $40 for the serial cable! After I explained that they sent me a cable (free of charge), got here in 2 or 3 days. The cable I have is a 940-0023A, that's probably the one you want. If you ask APC for the cable, they should send it to you, I've heard of several people getting them for free.
BTW: The linux software (apcupsd) supports more than just the dumb cable (I use a smart cable with my BackUPS-Pro 280 and it works fine).

IIRC, the linux software only supports the dumb cable. I think this
is the 940-0020B. I had to mail away for the dumb cable. Since I
don't have the Pro, the smart box, this wasn't much of a problem.

i have just gotten a back-ups 650, and looked on the apc open source page to see what their daemon was up to. what i noticed was that apparently the included cable doesn't work with linux. do you know offhand whether the apcupsd app supports the one supplied, 940-0020C? (the apcupsd docs mention supporting a 940-0020B; i'm wondering if this merely has to do with the age of the docs rather than any real difference in the cable.)
