LIEBERT(8) NUT Manual LIEBERT(8) NAME liebert - Driver for Liebert contact-closure UPS equipment SYNOPSIS liebert -h liebert -a UPS_NAME [OPTIONS] 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 in- terface. 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 lim- itation of any contact-closure driver.
