NAME

       liebert-gxe - Driver for Liebert GXE series UPS, using the YDN23 serial protocol

SYNOPSIS

       liebert-gxe -h

       liebert-gxe -a UPS_NAME [OPTIONS]

           Note

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

SUPPORTED HARDWARE

       Tested to work on the following units:

       •   Liebert GXE 01k00TS1101C00

               Note
               This UPS has an RS-232 port and a USB port. The USB port has an ACM interface which functions as
               a serial port for the host operating system. Both ports can be used managing the device.

       This is an experimental driver. You have been warned.

EXTRA ARGUMENTS

       This driver supports the following optional settings in ups.conf(5):

       addr=num
           Set the address of the UPS — 01 (default) ~ 99.

       retry=num
           Set the max times of read failures. (UPS sometimes ignores the incoming command and causes driver
           stales. The driver will ignore retry failures if occurred in a row. However, this does increase the
           latency if a real stale happened. Default to 3)
