NAME
       mge-shut - Driver for SHUT Protocol UPS equipment

SYNOPSIS
       mge-shut -h

       mge-shut -a UPS_NAME [OPTIONS]

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

SUPPORTED HARDWARE
       mge-shut supports all recent Eaton, MGE and Dell UPS models which use the SHUT (Serial HID UPS Transfer) protocol.

       Older MGE models, such as Pulsar ESV+, Pulsar EX and Pulsar ES+, use the U-Talk protocol and should use the mge-utalk driver.

EXTRA ARGUMENTS
       This driver also supports the following optional settings:

       lowbatt=num
	   Set the low battery warning threshold at which shutdown is initiated by upsmon(8).

	   The factory default value is 30 (in percent), and can be settable depending on the exact model.

       offdelay=num
	   Set the timer before the UPS is turned off after the kill power command is sent (via the -k switch).

	   The default value is 20 (in seconds). Usually this must be lower than ondelay, but the driver will not warn you upon startup if it
	   isn't.

       ondelay=num
	   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.

	   The default value is 30 (in seconds). Usually this must be greater than offdelay, but the driver will not warn you upon startup if it
	   isn't. Some UPS'es 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 ondelay = -1 in ups.conf helps.

       notification=num
	   Set notification type to 1 (no), 2 (light) or 3 (yes).

	   The default value is 3 (yes) because of some early Ellipse models which need it.

KNOWN ISSUES
   Repetitive timeout and staleness
       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.

       In this case, simply modify the general parameter "pollinterval" to a higher value (like 10 for 10 seconds). This should solve the issue.

       Using notification=3 might also help.
