liebertgxt2 (8) - Linux Man Pages

NAME

liebertgxt2 - Driver for Liebert GXT2 UPS, using the ESP2 serial protocol

NOTE

This man page only documents the hardware-specific features of the liebertgxt2 driver. For information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

liebertgxt2 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 features that aren't supported are shutdown and battery test - or any command 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
Force the model name of model to be a supported model, giving you the chance to try this driver with your Liebert UPS.

BUGS

Action commands are not supported, that includes battery test and shutdown.
