This man page only documents the hardware\-specific features of the mge\-shut driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.

.RE
.SH"SUPPORTED HARDWARE"
.sp
mge\-shut supports all recent Eaton, MGE and Dell UPS models which use the SHUT (Serial HID UPS Transfer) protocol\&.
.sp
Older MGE models, such as Pulsar ESV+, Pulsar EX and Pulsar ES+, use the U\-Talk protocol and should use the mge\-utalk driver\&.
.SH"EXTRA ARGUMENTS"
.sp
This driver also supports the following optional settings:
.PP
\fBlowbatt\fR=\fInum\fR
.RS4
Set the low battery warning threshold at which shutdown is initiated by
\fBupsmon\fR(8)\&.
.sp
The factory default value is 30 (in percent), and can be settable depending on the exact model\&.
.RE
.PP
\fBoffdelay\fR=\fInum\fR
.RS4
Set the timer before the UPS is turned off after the kill power command is sent (via the
\fB\-k\fR
switch)\&.
.sp
The default value is 20 (in seconds)\&. Usually this
\fBmust be lower\fR
than
\fIondelay\fR, but the driver will
\fBnot\fR
warn you upon startup if it isn\(cqt\&.
.RE
.PP
\fBondelay\fR=\fInum\fR
.RS4
Set the timer for the UPS to switch on in case the power returns after the kill power command had been sent but before the actual switch off\&. This ensures the machines connected to the UPS are, in all cases, rebooted after a power failure\&.
.sp
The default value is 30 (in seconds)\&. Usually this
\fBmust be greater\fR
than offdelay, but the driver will
\fBnot\fR
warn you upon startup if it isn\(cqt\&. Some UPS\(cqes will restart no matter what, even if the power is (still) out at the moment this timer elapses\&. In that case, you could try if setting
\fIondelay = \-1\fR
in
\fBups\&.conf\fR
helps\&.
.RE
.PP
\fBnotification\fR=\fInum\fR
.RS4
Set notification type to 1 (no), 2 (light) or 3 (yes)\&.
.sp
The default value is 3 (yes) because of some early Ellipse models which need it\&.
.RE
.SH"KNOWN ISSUES"
.SS"Repetitive timeout and staleness"
.sp
Some models tends to be unresponsive with the default polling frequency\&. The result is that you have some "data stale" errors in your system log\&.
.sp
In this case, simply modify the general parameter "pollinterval" to a higher value (like 10 for 10 seconds)\&. This should solve the issue\&.
.sp
Using \fInotification=3\fR might also help\&.
