    Command:

    optiups

    
    
    
    

    NOTE

           This man page only documents the hardware-specific features of the
           optiups driver. For information about the core driver, see
           nutupsdrv(8).
    
    
    

    SUPPORTED HARDWARE

           optiups was originally written against a PowerES 280es in nut-0.45. It
           was revised for nut-2.0.1 and tested against a PowerES 420E. It is
           expected to work with at least the PowerES, PowerPS, and PowerVS
           models.
    
           This driver additionally supports a Zinto D from ONLINE USV-Systeme AG
           because of their very similar commands, but it is unknown if it also
           works with other UPS from them.
    
           This driver will not work with the PowerES stock serial cable. You will
           need to construct your own three conductor cable:
    
               UPS 6 -> PC 3
               UPS 9 -> PC 2
               UPS 4 -> PC 5
    
           The cable for Online-USV uses pin UPS 7 (not UPS 4) -> PC 5.
    
    
    

    EXTRA ARGUMENTS

           This driver supports the following optional settings in the ups.conf(5)
           file:
    
           status_only
               Only poll for critical status information. Without this, optiups
               (and all NUT drivers) poll all sorts of information from the UPS
               fairly often. It is probably not often enough to hurt anything, so
               this option probably is not very useful, unless you have a flaky
               serial connection or a highly loaded machine.
    
           nowarn_noimp
               Does not print warnings when the UPS reports that a variable is not
               implemented or not pollable. Without the option you will get a
               message sent to your system logs each time NUT polls the UPS. If
               you specify nowarn_noimp, this message will only be logged once.
    
           fake_lowbatt
               This forces the low battery flag true. Without it, if you want to
               test your UPS, you will have to unplug it and wait until the
               battery drops to a low/critical voltage level before NUT will
               respond and power down your system. With the flag, NUT should power
               down the system soon after you pull the plug. When you are done
               testing, you should remove this flag.
    
               For basic shutdown configuration testing, the command upsmon -c fsd
               is preferred.
