UPS setup with multiple computers
Just getting my hands dirty with unRAID and finally have a basic system up and running for a few days now.

My first thought was to configure a script on my Mac to send an SSH command to unRAID to tell it to shutdown. I'm still learning where a
Just be VERY sure that you think through all the timing issues when chaining one to another. If your ethernet switch isn't on battery backup, your messages won't get through. If your master machine shuts down too quickly, your slave machines won't shut down. The way I handle it is a successively longer set of shutdown times specified in the apcupsd config, so all the slave machines should have shut down well before the master runs out of battery.
