NAME

mge-shut, newmge-shut - Driver for SHUT Protocol UPS equipment

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 support 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 supports the following optional settings in the ups.conf(5):
lowbatt=num
Set the low battery warning threshold at which shutdown is initiated by upsmon(8). The factory default value is 30 (in percentage), and only 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), and MUST BE LOWER than ondelay.
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 3 (in 10 seconds units, which means 30 seconds), and MUST BE GREATER than offdelay.
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

Pulsar Ellipse S: Repetitive stale status - Loss of communication

Several users have reported "data stale" errors with Pulsar Ellipse equipment. This lasts around 10 seconds and happens once every few hours. This is due to the fact that the SHUT protocol is verbose, and the driver sometimes does not handle all of it during the usual polling interval in upsd. To solve this problem, change the value of MAXAGE to 25 in upsd.conf. Also add "notification=3" in ups.conf (thanks to Julien Lesaint and Fabien).
