0x00000111 Posted October 15, 2020 Share Posted October 15, 2020 I have an older UPS with a serial only connection and I have a USB to serial port adapter which seams to be recognized by unraid on /dev/ttyS0. Any idea on how to configure the UPS Settings? I've tried pretty much every combo. https://www.cyberpowersystems.com/product/ups/smart-app-lcd/cps1500avr/#tab-additional_information Quote Link to comment
Frank1940 Posted October 15, 2020 Share Posted October 15, 2020 The link that you posted has a back panel picture that has a USB port on the back of it. Use that port. If that picture (or link) is not your actual UPS, you will need to locate a manual for it as some UPS are configurable from the UPS itself. I also seem to recall that there were some UPS's that used some sort of weird serial/UBS cable... Quote Link to comment
0x00000111 Posted October 15, 2020 Author Share Posted October 15, 2020 It's apparently not. I'm the admin for the server, but not on site as it's my client's server. Here's the photos: Quote Link to comment
0x00000111 Posted October 15, 2020 Author Share Posted October 15, 2020 It would be a nice to have since this location sustains power outages pretty often. I'm thinking of having them buy another smaller UPS with a USB port just so unraid can detect power outages and do a graceful shutdown as required. Quote Link to comment
Frank1940 Posted October 15, 2020 Share Posted October 15, 2020 Look here: It looks like CyberPower has been making UPS's using this same model number when they have, in fact, redesigned the hardware. I don't know what you know (or can remember in my case) but setting up Serial link was always a bit of challenge. You have to know the baud rate, number of bits and parity. You may have to try and find a manual that matches the hardware that you have. I also seem to recall that not all UBS-to-serial port adapters will work in every application. 1 minute ago, 0x00000111 said: It would be a nice to have since this location sustains power outages pretty often.

If you are a paid consultant and charging them by the hour, that could be the cheapest solution! You might actually want to look for a unit which provides full sine wave output as that is a bit easier on the server's PS. (It sound like you want to run on the battery for a fair period of time. I should also point that doing so leaves a risk factor if you restart the server before the battery recharges and then have second power outage!) Quote Link to comment
0x00000111 Posted October 20, 2020 Author Share Posted October 20, 2020 Ok, So I bought a APC Battery Back-UPS, 675VA, It's got a USB data port, but it's now not being detected. Tried pretty much every possible combo of settings. 😕 https://www.samsclub.com/p/apc-battery-back-ups-675va/prod20142192 Quote Link to comment
Frank1940 Posted October 20, 2020 Share Posted October 20, 2020 (edited) Start here: https://forums.unraid.net/topic/74208-apc-smartups-setup/ If you don't find anything that makes it work, try googling APC UPS not working unraid.net EDIT: Or return it and get a Cyberpower UPS. (I seem to recall that they are more compatible.) I understand that the apcupsd package that is used in Unraid has nothing to do with the APC company. You can also try the NUT plugin.
