[Nut-upsuser] Need help with Unitek Alpha 1200sx.

Tue Oct 7 19:21:32 UTC 2008

Hi,
Apologies for picking up on this old thread but I never had gotten this
issue resolved and I'm now back in the location where the UPSs are so I was
hoping we could look into the issue again.

Basically, I had two Unitek Alpha 1200sx UPSs, connected to Fedora Linux 8.
The NUT version seems to be:

Network UPS Tools upsd 2.2.0-
not listening on 0.0.0.0 port 3493

The driver seems to be the megatec_usb driver. The problem I have is that
this only seems to work occasionally (I typically have to restart the deamon
several times, switch on/off the UPSs etc in order to get it to work). Most
of the time, the controller seems to fail to start up and I subsequently get
the following message:

Broadcast message from nut (Tue Oct  7 21:14:44 2008):

UPS unial1200 at localhost is unavailable

I'm not quite sure what other information you'd need. That said, I can
provide any output requested.

Thanks in advance for helping me out.

Joe
