APC UPS w/ USB signal cable - work in Linux?


Our company just recieved (for free) several 350VA APC Back-UPS ES Series UPS devices that use a USB cable to attach to the server/system.

I would like to configure our linux server (SUSE 9.0) to automatically /cleanly shutdown during a power failure. Unfortunately I can't seem to find any information regarding the USB interface and Linux? Any chance I can get this running under linux? Or (alternatively) could I make my own serial cable that will run with known working linux packages?

I really wouldnt mind even getting some general information regarding UPS configuration under linux in general if anyone can help with that as well. What does everyone use? How difficult (generally speaking) is it to set up UPS support under linux? Surprisingly I cant find any modules or help document on my SUSE box, and my google searches have been fruitless as well.

Any help would be greatly appreciated!

Well, I'd sure like to be let in on the secret handshake if it's supposed to be so easy.

I have suse 9.0 recently installed on a new box based on a asus p4bgv-mx motherboard and I installed apcupsd via yast2 and I have a backups-es 725 plugged in and it's the only usb device and it sure isn't working merely by following the surface directions.


linux:~ # apcupsd --version

Perhaps it's a bad interaction with hotplug or usbd?

....

OK, i got it working. While I was assembling the details for this post I noticed in the config file comments about the old vs new values for device type.
I changed
UPSTYPE backups
to
UPSTYPE usb

and everything else above just the same and "etc/rc.d/apcupsd start"
worked immediately.

I decided to go ahead and post for the sake of the next guy who thinks it doesn't work right away. But I no longer have a question.

Thanks for the help!

And since I am the next guy who did not think it worked right away, I thank you. :-)

I am a next guy who think it could very well work right away, but have no cable. The manual refers to DB9, but what I see is an RJ-45 with 9 leads.

How do I go about it to build a cable?

Different models of APC's come with different connectors. Some with rs232 via db9, some with usb via keyed 10-pin rj45.
You don't build the usb cable. Even though the proper cable will cost more than such a simple cable really should, Finding 10p10c/rj50 (like rj45 but with 10 pins instead of 8) plugs, and a 10-pin rj50 crimper tool and a sacrificial standard usb cable will cost even more than just getting the proper cable on-line.

You can't use ordinary rj45 plugs because, of course, both of the outer-most pins are used, which don't exist on rj45.

I won't post a link to an ebay or nextag listing since they'll just be dead later.
Just Google for AP9827 or 940-0127D to buy a cable.
Least I can find is $15 - $20 on ebay and a few other places.

And here is the pinout if you have access to 10p10c plugs and crimper.
