hi,
[sol8, apc powerchute ent. edition]
got a problem with my ups after replacing the batterie..
there is no connection to the ups. when i plug this ups into a windows - laptop i can speak to it, but in solaris not. there are no messages in powerchute.err and the deamon upsd is running. restarting the deamon doesn't change anything. solving the problem i 've seen that there is no entry in the powerchute.ini, where the hardwarepath should be. i think that that is the problem.
anyone knows how to reconfigure these setting?
thx a lot
greetings Preßy
I found one link at docs.sun.com, but this may be way off; I'm not sure:
Appendix A - Installing and Configuring an Uninterruptible Power Supply (UPS)
thx for the quick answere... i also found that docu on docs.sun.com but this explains how to integrate the ups into the RSC-Card/Program there is no readme about powerchute on docs.sun neither on sunsolve... ;-(
waiting for other good ideas 
greetings Preßy
pressy i use powerchute plus for sol8.
are you useing smart signaling or dumb signaling?
if you dont have any comm going on check the port listed in powerchute.ini.
DUMB:
[ Ups ]
SignallingType = Simple
PortName = /dev/ttya
AutoUpsRebootEnabled = Yes
AllowedPortNames = /dev/ttya,/dev/ttyb
SMART:
[ Ups ]
SignallingType = Smart
PortName = /dev/ttyb
AutoUpsRebootEnabled = No
AllowedPortNames = /dev/ttya,/dev/ttyb
And if I remember correctly, if the server only has one port, it is shared as A and B and you need a special cable from Powerchute to make it work on either A or B (your serial ports).
