nut-ipmipsu - Driver for IPMI Power Supply Units (PSU)

       Arnaud Quette <arnaud.quette@free.fr>

       This driver doesn’t support any optional settings.

       The port value is used to identify the PSU. For instance, to target FRU 0x2, use the following in
       ups.conf:

           [pdu]
                   driver = nut-ipmipsu
                   port = id2

       This driver will report various information related to a PSU, including:

       •   manufacturer, model, serial and part numbers,

       •   nominal voltage and frequency,

       •   actual current and voltage,

       •   status of the PSU:

           •   OL means that the PSU is present and providing power,

           •   OFF means that the PSU is present but not providing power (power cable removed),

           •   stale (no data) means that the PSU is not present (i.e. physically removed).

       Here is an example output for a Dell r610 server:

       This driver may be not built by default. You can build it by installing the libfreeipmi-dev dependencies
       and using configure --with-ipmi=yes.

       You also need to give proper permissions on the local IPMI device file (/dev/ipmi0 for example) to allow
       the NUT user to access it.

       An udev rules file (nut-ipmipsu.rules) is provided and automatically installed on an udev enabled system.
       This file is generally installed in /etc/udev/rules.d/, or /lib/udev/rules.d/ on newer systems, to
       address the permission settings problem.

       For more information, refer to scripts/udev/README.adoc in NUT sources.

       This driver doesn’t support any instant commands.

       This driver should support a wide range of PSUs through local IPMI interface.

       nut-ipmipsu currently uses the GNU FreeIPMI project, for IPMI implementation.

           Note

           This driver is experimental, and still a work-in-progress. Feedback is encouraged.

           Note

           This man page only documents the hardware-specific features of the nut-ipmipsu driver. For
