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
|
|
|
|
|
linkman: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
|
|
|
|
|
linkman: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).

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.
