MGE-SHUT(8)                       NUT Manual                       MGE-SHUT(8)


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.

               Warning
               ondelay parameter was set in ten seconds unit in the legacy
               mge-shut driver ( 3 for 30 seconds) . It is now set in seconds
               ( 30 for 30 seconds). Make sure you use the correct unit in
               your configuration.

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

           This argument is ignored. It is only here for backward
           compatibility.


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.
