LIEBERT(8)                        NUT Manual                        LIEBERT(8)



NAME
       liebert - Driver for Liebert contact-closure UPS equipment

NOTE
       This man page only documents the hardware-specific features of the
       liebert driver. For information about the core driver, see
       nutupsdrv(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
       fundamental limitation of any contact-closure driver.
