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.
