NOTE

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

SUPPORTED HARDWARE

       This  driver supports some Liebert UPS equipment with a contact-closure
       interface.  This includes the UPStation GXT2 with their contact-closure
       cable.   The  smart  mode  ("Multilink") cable is not supported by this
       driver.

EXTRA ARGUMENTS

       This driver does not support any extra settings in the ups.conf(5).

BUGS

       This driver does not yet support shutdowns by raising  DTR.   Be  aware
       that  shutdowns  are not possible with the stock contact-closure cable.
       You may have to build another cable with DTR connected through  to  the
       UPS for it to work.

       There  is  no  way for this driver to detect the hardware or cable.  It
       will start up successfully even if no UPS is present.  This is a funda-
       mental limitation of any contact-closure driver.
