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.
