I connected the UPS on the USB port and looked for it with lsusb but it doesn’t show up. I unconnected it and looked with lsusb again if I can see any change but nothing changed.
Before I connected the UPS with the server it was connected with a Windows computer and worked fine.
there are many apliances that work fine with windows and don’t work with linux… you’d ask their manufacturers why…
login as root in a CLI console, ups disconnected
give the command:
tail -f /var/log/messages
plug in the usb cable and see what happens… and paste here the lines
finally, a suggestion: before buying anything you what to use with/on your linux/NS server, check it’s supported… maybe it will cost you some bucks more, but your life will be easier
@zamboni The UPS comes with an Linux software and should run.
I did install the rpm package and I can open the GUI via the browser. The scan can’t find the UPS. I started to search how I can find out which device is connected on a USP port and the results I posted.
In the mean time I tested the connection via RS232, which the UPS and the server has as well, and it works.
But I will know why it doesn’t work and how I can solve this problem. for the next time I have it.
I will write the result of the command maybe tomorrow. At the moment I am not at home.
