col
NOTE
This man page only documents the hardware‐specific features of the
liebertgxt2 driver. For information about the core driver, see nutups‐
drv(8).
SUPPORTED HARDWAREliebertgxt2 is experimental and will recognize only those models known
to work. The driver will report the model it finds and abort if it is
unknown. modelname= in ups.conf can be used to force the driver to
accept the model as supported.
The driver is incomplete but supports the numerious information fields
and fields necessary to make the driver useful. Potentially useful fea‐
tures that aren't supported are shutdown and battery test - or any com‐
mand that instructs the UPS to take some action.
CABLING
This driver expects to see 2400 baud serial data at the TX/RX pins.
This driver was tested with an original cable.
EXTRA ARGUMENTS
This driver supports the following optional settings in the
ups.conf(5):
modelname=model

you the chance to try this driver with your Liebert UPS.
BUGS
Action commands are not supported, that includes battery test and shut‐
down.
