mge-shut - Driver for SHUT Protocol UPS equipment
mge-shut -a UPS_NAME [OPTIONS]
This man page only documents the hardware-specific features of the mge-shut driver. For information about the core driver, see nutupsdrv(8).
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.
This driver also supports the following optional settings:
The factory default value is 30 (in percent), and can be settable depending on the exact model.
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.
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 UPSes 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.
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.
This argument is ignored. It is only here for backward compatibility.
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.
