openmediavault-nut, APC Smart-UPS XL 750VA and APC AP9630 NMC CARD 2

  • Hi!

    Recently upgraded from a local APC UPS connected with a USB cable to the APC Smart-UPS XL 750VA with an APC AP9630 NMC CARD 2 connected via ethernet.

    Have tried configuring it in the "Services" >> "UPS" section with:



    'Standalone' for local UPS, 'Netclient' for remote UPS on a NUT server.

    Identifier *


    The name used to uniquely identify your UPS on local or remote system.


    Smart-UPS 1000INET

    Netclient hostname

    Netclient user name


    Netclient password




    The number of power supplies that the UPS feeds on this system (usually 1), refer to upsmon.conf(5) for more information.

    Shutdown mode

    UPS reaches low battery

    Defines when the shutdown is initiated.

    Keep getting the error "Communications with the UPS apc@ cannot be established" in my mail, and no status for the UPS under "Diagnostics" >> "Services" >> "UPS". It does however throw an error "Error. Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; upsc 'apc@' 2>&1' with exit code '1': Error: Connection failure: Connection refused".

    What am I missing here?
