Ihave a technical question: my sagetv server is attached to an APc ups in slave mode and my unraid box is master. i am out of town and my sage server has crashed and is unaceesible either by logmein or splahtop. i need to reboot the sage server and want to know if it is possible to power down the ups forcing attached computers to shut off and then get the ups back on line hopefully rebooting the computers . not sure if the WOL will work but that way i can give it a shot. i have 5b14 installed with the apcupsd plugin, have set kill ups to yes and nothing has mhappened. is there a command via telnet( i have another computer on the network that is up and running for use to control the unraid box) that i can use to shut down the ups device. is there also some other method that folks use to remotely force a reset, warm boot of computer that are no longer accessible?? thx

Even if you could shut down the UPS, what then happens to the server?  If it is also on the UPS it will have no power so WOL will not be able to wake it up again.  What you would need to do is to have the UPS be given a command to shut down for a just short period before it comes back up automatically.  I am not aware that there is any way to do that.

I've used one of these  http://www.securitystoreusa.com/Multi-Link-PowerStone-Remote-AC-Controller-p/powerstone.htm for a similar problem,  It connects between the power...  eg. UPS and server(s) and also connects to a phone line.  If things die, you call  the number and the PowerStone will answer with a beep or two, then you dial the secret code and it turns the power off for 5 seconds then back on.  I used it on a second number on distinctive ring with my main number so that I did not have to have an additional physical phone line.  It can be configured answer ONLY on the distinctive ring pattern. 

 

1800 Watt capacity, so they will handle some pretty hefty combinations of equipment.

 

Just make sure all the necessary equipment is set to resume the previous power state so they will come back to life after the power cycle.

 

Worked for me, but YMMV !
