I have a Powerware PowerRite XT (PRXT0600A), which I am attempting to configure with nut over RS232, to allow for clean shut downs.
However, so far I haven't had any luck trying to talk to it, or work out what language it speaks even. Its like it I forgot to plug it in in fact, I am not getting any response to anything.
Is there any hope? Or should I be looking at getting a newer UPS that I know will work with nut?
NFI about that particular unit, but strategies I have found successful in the past are: - ask the vendor (but don't necessarily believe them). - google the name plus "nut" or so. - if it supports e.g. both USB and RS232, try both. - just run each nut driver by hand and see if it complains, e.g. "/lib/nut/megatec_usb -a foo -D" Once you know what nut driver to use, it should be straightforward. If you're running a stable OS, it is also worth doing this investigation on a recent release in case nut has grown support for your unit in the interim. Here is an example if you've never used nut before: root@omega:~# egrep -v '^[[:space:]]*(#|$)' /etc/nut/* /etc/nut/nut.conf:MODE=netserver /etc/nut/ups.conf:[upset] /etc/nut/ups.conf:driver = megatec_usb /etc/nut/ups.conf:port = unused /etc/nut/upsd.conf:LISTEN * 3493 /etc/nut/upsd.users:[monslave] /etc/nut/upsd.users:password = UNPRINTABLE /etc/nut/upsd.users:upsmon slave /etc/nut/upsd.users:[monmaster] /etc/nut/upsd.users:password = UNPRINTABLE /etc/nut/upsd.users:upsmon master /etc/nut/upsmon.conf:MONITOR upset@localhost 1 monmaster UNPRINTABLE master /etc/nut/upsmon.conf:SHUTDOWNCMD "/sbin/shutdown -h +0" /etc/nut/upsmon.conf:POWERDOWNFLAG /etc/killpower /etc/nut/upssched.conf:CMDSCRIPT /upssched-cmd PS: there is also acpupsd, but AFAIK that only speaks the APC protocol and non-APC brands don't speak it, so it is not for you.
