# LIEBERT-GXE(8)

## 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)
