So I have two APC UPS devices: Back-UPS ES 500 and 725. These two UPSes work fine but recently we had an extended outage and both of our servers connected to these UPSes shutdown and one of them had a RAID Drobo that suffered disk damage.
Now I need to figure out how to make both of these machines shutdown gracefully when the batteries in the UPSes get low. I am looking at APCUPSD from this post:
I like the program but I have some weird issues. I'm not sure how to connect these UPSes to the Ubuntu servers. The UPSes both have phone jacks (for protection) and one network jack for, presumably, communication. The ES 725 has two coaxial jacks as well.
Am I to assume that I need some kind of network to USB cable for communication between my servers and these UPSes? Any hints or feedback would be very appreciated.
