.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:
