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

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

This man page only documents the hardware\-specific features of the nut\-ipmipsu driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
.sp .5v
.RE
.SH "SUPPORTED HARDWARE"
.sp
This driver should support a wide range of PSUs through local IPMI interface\&.
.sp
nut\-ipmipsu currently use the GNU FreeIPMI project, for IPMI implementation\&.
.SH "EXTRA ARGUMENTS"
.sp
This driver doesn\(cqt support any optional settings\&.
.SH "INSTALLATION"
.sp
This driver is not built by default\&. You can build it by using "configure \-\-with\-ipmi=yes"\&.
.sp
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\&.
.sp
An udev rules file (nut\-ipmipsu\&.rules) is provided and automatically installed on 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 nut/scripts/udev/README\&.
.SH "INSTANT COMMANDS"
.sp
This driver doesn\(cqt support any instant commands\&.
.SH "IMPLEMENTATION"
.sp
The "port" value is used to identify the PSU\&. For instance, to target FRU 0x2, use the following in \fBups\&.conf\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
[pdu]
        driver = nut\-ipmipsu
        port = id2
.fi
.if n \{\

.sp
This driver will report various information related to a PSU, including:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

manufacturer, model, serial and part numbers,

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

nominal voltage and frequency,
.RE
.sp
.RS 4
.ie n \{\

.el \{\

.sp
.RS 4
.ie n \{\

.el \{\

.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

.ie n \{\

.el \{\

.el \{\
