a12vman Posted April 30, 2017 Share Posted April 30, 2017 Hi- I am seeing the dreaded lost communication with UPS message. Was working fine for quite a while but suddenly stopped. I have the APC Backup-UPS 550 Nothing wrong with the APC UPS itself, I tested communication between my Win 7 Laptop via USB and the APC Software. Here are my UPS Settings, I don't have any extra UPS-related plugins installed: APC 001,017,0449 DATE 2017-04-30 13:48:34 -0400 HOSTNAME MediaTower VERSION 3.14.13 (02 February 2015) slackware CABLE Custom Cable Smart DRIVER APC Smart UPS (any) UPSMODE Stand Alone STARTTIME 2017-04-30 13:47:34 -0400 STATUS Lost communication MBATTCHG 40 Percent MINTIMEL 10 Minutes MAXTIME 0 Seconds NUMXFERS 0 TONBATT 0 Seconds CUMONBATT 0 Seconds XOFFBATT N/A STATFLAG 0x05000100 END APC 2017-04-30 15:34:07 -0400 Link to comment
Frank1940 Posted April 30, 2017 Share Posted April 30, 2017 I can suggest two things. First, get a diagnostics file ( "Tools" >>> "Diagnostics" ) and post it up with your next post. Second Thing: Try and new UPS cable (I've got a pile of them laying around-- hopefully you do to) and use a UBS2 port. (Some UBS3 ports on some MB's seem to occasionally get 'lost' with unRAID.) EDIT: and don't reboot before you get that diagnostics! Link to comment
Frank1940 Posted April 30, 2017 Share Posted April 30, 2017 Start and stop the UPS service ( 'Settings' >>> 'UPS Settings' >>> 'UPS Settings' ) after each change you make while testing things. I don't know if this is necessary as I haven't seen a lot of problems with the UPS software and unRAID on the forum so no one has a lot of experience in trouble shooting... Link to comment
a12vman Posted April 30, 2017 Author Share Posted April 30, 2017 Logs are attached. I will look for a different USB cable but I do know that it works as I used it to test with my Win 7 laptop. Also my server doesn't have any USB 3.0 ports. mediatower-diagnostics-20170430-1647.zip Link to comment
unevent Posted April 30, 2017 Share Posted April 30, 2017 Try setting 'UPS Cable: usb' and 'UPS Type: usb'. Based on the logs you are using a USB cable and not the APC serial to USB cable so I don't see a need for the custom cable type. Your Back-UPS ES 550G is not a 'smart' UPS so the standard USB driver is needed. Unplug and plug back in the USB cable after making the changes, if needed. Link to comment

Frank1940 Posted April 30, 2017 Share Posted April 30, 2017 9 minutes ago, a12vman said: Online 100.0 Percent 11.6 Minutes - - 29.0 Percent Make sure your 'Time on Battery before shutdown' is very short. (I would be setting it for less than a minute.) You don't have a lot of battery reserve and this becomes an issue when you have a power outage and then the power in all restored. You think everything is alright and turn the server back on. Now the power goes out again and the battery hasn't recharged enough to be able to get the server shutdown before the battery is discharged. (Full recharge time is more than eight hours for inexpensive UPS's.) Link to comment

av8or Posted February 27, 2018 Share Posted February 27, 2018 Setup a new server (second server) running 6.2.4 and unable to get the UPS set up correctly. Have read the posts above and a few others. Not able to resolve. Initially sees the APC UPS and then "lost communication." I had the NUT plugin (deprecated and current) installed for a brief time but wanted to stick with the APCUPSD instead. Attached is a screen shot of the details and the log. Any help solving would be appreciated.... UPS Log.txt Link to comment

av8or Posted February 28, 2018 Share Posted February 28, 2018 SOLVED..... Pulled the USB again but this time used an adjacent USB connection. Communication restored. Strange, but solved the issue. Link to comment
