           apcsmart -h
           apcsmart -a 'UPS_NAME' [-x option=value ...]
               This man page only documents the hardware-specific features of the
               apcsmart driver. For information about the core driver, see


           The apcsmart driver should recognize (or at the very least work with)
           majority of Smart-UPS models - which includes Smart-UPS, Matrix-UPS and
           Back-UPS lineups, among few other ones.
           Currently we can roughly divide APC hardware into 3 groups (note that
           the division isn't strict by any means, and the borders between those
           are pretty fuzzy):
           [very] "old" models
               These models usually have old APC logo, white color and no
               programmable eeprom; You won't find them listed anywhere on APC's
               site either. The support for those will be usually based on
               driver's compatibility tables, or if the model (firmware) is not
               listed in those - the driver will try to follow the very basic
               subset of features, while still trying to remain useful. Despite
               "smart" tagname, they often tend to behave in pretty dumb way (see
               the section below about shutdown behaviour).
               Example models:
               ?   Smart-UPS 2000I
               ?   Smart-UPS 900I
           "new" models
               These models usually come from late 1990s / pre-2009 times. They
               are often referred as "3rd. gen". For the most part, they have
               programmable eeprom, report supported commands and capabilites, and
               should work just fine with the apcsmart driver.
           "microlink" models
               WARNING: these are not natively supported by apcsmart (or apcupsd
               for that matter, if you're wondering). Around 2007 APC (now APC
               Schneider) decided to go back to its proprietry roots and all the
               new models (SMT, SMX, SURTD) use completely different protocol and
               cables. If you purchased a new APC ups, that uses cable with rj45
               on the one end, and db-9 on the other - then you have such model.
               Your only option to support it through NUT is to purchase "legacy
               communications card" - part #AP9620 (google 'AP9620' for more
               details). Or if that's not an option, rely on official software.
               It was reported, that the 940-0024E cable uses the same wiring as
               the 940-0024C one.
           You can specify alternate cable in ups.conf(5):
           Alternatively, you can also provide it on the command line using:
           -x cable=940-0095B


           APC hardware supports a lot of shutdown methods, that themselves can
           differ in behaviour quite a bit, depending on the model.
           S (soft hibernate)
               This is most basic command present in probably all APC models. It
               will hibernate the UPS, and subsequently wake it up when the mains
               supply returns.  The command doesn't work if UPS is running on
               "old" models
                   The behaviour here is unfortunately pretty primitive - when the
                   power returns, the ups just wakes up. No grace periods, no min.
                   battery charge condition, etc. This is probably not what you
               "new" models
                   The behaviour here is as expected - the power is cut off after
                   the eeprom defined grace period. The ups will wake up when the
                   power returns, after the eeprom defined delay AND if the eeprom
                   defined min. battery charge level is met. The delay is counted
                   from the power's return.
           CS (aka "force OB hack")
               This is a trick to make UPS power down even if it's running on
               mains. Immediately before issuing S, "simulate power failure" is
               issued. The remaining behaviour is as in S case.
               The name came from APC CS models, where such trick was used to
               power down UPSes in consistent fashion using only S. It's better to
               use @nnn command if your UPS supports it (and is not too old, see
           @nnn (hard hibernate)
               This is basic command used to hibernate UPS regardless if it's
               running on batteries or on mains. The option takes 3 digits
               argument which can be used to specify additional wakeup delay (in 6
               minute units).
                   eeprom defined delay. UPS will not power up if it's running on
                   batteries, contrary to what "old" models used to do - the
                   combined delay is counted from the moment of power return.
               Supposedly there exist models that take 2 digits instead of 3. Just
               in case, NUT also supports such variation. You have to provide
               exactly 2 digits to trigger it (awd option, or argument to one of
               the supported instant commands).
           K (delayed poweroff)
               This is permanent poweroff - the ups will not wake up
               automatically. On newer units, it will respect applicable eeprom
           Z (instant poweroff)
               This is also permanent poweroff - the ups will not wake up
               automatically. The poweroff is executed immediately.


           There're 3 options used to control shutdown behaviour.
               This option takes a single digit (0-5) as an argument. See below
               for details.
               This option takes string of digits as an argument. Methods listed
               are tried in turn until one of them succeedes. Note that the
               meaning of digits is different from sdtype. See below for details.
               This option lets you specify additional wakeup delay used by @. If
               you provide exactly 2 digits, the driver will try 2 digits
               variation (see previous section for more info). Otherwise standard
               3 digits variation is used.  Note: the time unit is 6 minutes !
           Keep in mind that sdtype and advorder are mutually exclusive. If
           advorder is provided, sdtype is ignored. If advorder is set to 'no',
           sdtype is used instead.
           If nothing is provided, NUT will assume sdtype=0 - which is generally
           fine for anything not too ancient or not too quirky.
           The values permitted are from 0 to 5. Only one can be specified.
           Anything else will cause apcsmart to exit.
               issue soft hibernate (S) if the ups is running on batteries,
               otherwise issue hard hibernate (@)
               Hard hibernate's additional wakeup delay can be provided by awd.
           The argument is either a word 'no', or a string of 1 - 5 digits in [0 -
           4] range. Each digit maps to the one of shutdown methods supported by
           APC upses. Methods listed in this way are tried in order, until one of
           them succedes.
           If advorder is undefined or set to 'no', sdtype is used instead.
           The mapping is as follows:
           0   soft hibernate (S)
           1   hard hibernate (@)
           2   delayed poweroff (K)
           3   instant poweroff (Z)
           4   "force OB hack" (CS)
               Hard hibernate's additional wakeup delay can be provided by awd.


           APC units - even if they report LB mode - will not go into shutdown
           automatically. This gives us even more control with reference to "when
           to actually shutdown psu". Since version 2.6.2, NUT supports ignorelb
           option in driver's section of ups.conf(5). When such option is in
           effect, the core driver will ignore LB state as reported by specific
           driver and start shutdown basing the decision only on two conditions:
           battery.charge < battery.charge.low
           battery.runtime < battery.runtime.low
           Of course - if any of the variables are not available, the appropriate
           condition is not checked. If you want to explicitly disable one of the
           conditions, simply override the right hand variable causing the
           condition to always evaluate to false (you can even provide negative
           APC upses don't have battery.charge.low - you will have to define it if
           you want to use such condition (prefix the variable with override. or
                   override.battery.runtime.low = -1
           This would cause apcsmart to go into shutdown only if detected battery
           charge < 15%. Runtime condition is always false in this example.
           You could ask - why bother ? Well, the reason is already hinted above.
           APC units can be very picky about the batteries, and their firmware can
           underestimate the remaining runtime (especially right after going into
           OB state). ignorelb option and override.* let you remain in control of
           the ups, not ups in control of you.
           Furthermore, this allows to specify conditions similary to how it's
           done in apcupsd daemon, so it should be welcome by people used to that


           The apcsmart driver exposes following instant commands:
               executes soft hibernate
           shutdown.return cs
               executes "force OB hack"
           shutdown.return at:<nbr>
               executes "hard hibernate" with <nbr>*6 minutes additional wakeup
               delay (<nbr> format is the same as of awd option)
               executes "delayed poweroff"
               executes "instant poweroff"
           All the above commands must be issued 2nd time to have any effect (no
           less than 3 seconds, and no more than 15 seconds after the initial
           call). Those commands are mostly useful for manual testing, when your
           machine is not powered by the ups you're testing.
           Other supported commands:
           ?   load.on
           ?   test.panel.start
           ?   test.failure.start
           ?   test.battery.start
           ?   test.battery.stop
           ?   bypass.start


           Nigel Metheringham <> (drawing
           heavily on the original apcsmart driver by Russell Kroll). This driver
           was called newapc for a time and was renamed in the 1.5 series. In
           2.6.2 it was renamed to apcsmart-old, being superseded by updated
           version with new features, which is maintained by Michal Soltys
