UPS hardware problem

[Tina Waitherwerch]

I have 2 N class 9000/800's that I'm trying to activate the ups monitoring daemon. It seemed easy enough, but when I checked syslog.log, I got lots of the following:
Aug 6 09:06:59 mbhpu09 /usr/lbin/ups_mond[22789]: /usr/lbin/ups_mond: UPS Monitor daemon starting; using configuration file /etc/ups_conf

Aug 6 09:11:52 mbhpu09 /usr/lbin/ups_mond[22789]: /usr/lbin/ups_mond: terminated by signal 15

I got this on both machines. Do you think BOTH machines have a hardware problem at the same time or have I missed a step setting it up?

Thanks,

Tina,
which UPSes do you use? HP ones? Did you use comm cable shipped with them?
For example, APC UPSes use their own made especially for hpux servers serial comm cable, and will NOT work with ups_mond (need to use APC's software called PowerChute)

I agree with Eugene. I think you might have a cable pin out problem. Look at the pinout requirements for the UPS that you are using.

a found my answer rummaging through some old forums. Apparently, I had both ups_mond and UPS MANAGER II running at the same time - which is a no-no and causes the daemons to have software conflicts. Why didn't SAM stop me from activating ups_mond when I didn't know I even had a UPS Manager II?

Thanks
