13 Note
14 This man page only documents the hardware-specific features of the
15 mge-shut driver. For information about the core driver, see
16 nutupsdrv(8).
17
19 mge-shut supports all recent Eaton, MGE and Dell UPS models which use
20 the SHUT (Serial HID UPS Transfer) protocol.
21
22 Older MGE models, such as Pulsar ESV+, Pulsar EX and Pulsar ES+, use
23 the U-Talk protocol and should use the mge-utalk driver.
24
26 This driver also supports the following optional settings:
27
28 lowbatt=num
29 Set the low battery warning threshold at which shutdown is
30 initiated by upsmon(8).
31
32 The factory default value is 30 (in percent), and can be settable
33 depending on the exact model.
34
35 offdelay=num
36 Set the timer before the UPS is turned off after the kill power
37 command is sent (via the -k switch).
38
39 The default value is 20 (in seconds). Usually this must be lower
40 than ondelay, but the driver will not warn you upon startup if it
41 isn’t.
42
43 ondelay=num
44 Set the timer for the UPS to switch on in case the power returns
45 after the kill power command had been sent but before the actual
46 switch off. This ensures the machines connected to the UPS are, in
47 all cases, rebooted after a power failure.
48
49 The default value is 30 (in seconds). Usually this must be greater
50 than offdelay, but the driver will not warn you upon startup if it
51 isn’t. Some UPS’es will restart no matter what, even if the power
52 is (still) out at the moment this timer elapses. In that case, you
53 could try if setting ondelay = -1 in ups.conf helps.
54
55 Warning
56 ondelay parameter was set in ten seconds unit in the legacy
57 mge-shut driver ( 3 for 30 seconds) . It is now set in seconds
58 ( 30 for 30 seconds). Make sure you use the correct unit in
59 your configuration.
60
61 notification=num
62 Set notification type to 1 (no), 2 (light) or 3 (yes).
63
64 This argument is ignored. It is only here for backward
65 compatibility.
66
68 Repetitive timeout and staleness
69 Some models tends to be unresponsive with the default polling
70 frequency. The result is that you have some "data stale" errors in your
71 system log.
72
73 In this case, simply modify the general parameter "pollinterval" to a
74 higher value (like 10 for 10 seconds). This should solve the issue.
75
76 Using notification=3 might also help.
