Got my Uninterruptable Power Supply (a.k.a. UPS) installed and now it seems to be running alright. Thanks to the apcupsd driver which offers much in terms of monitoring the power supply and getting your servers shutdown cleanly in case of electrical spikes and/or interrupted power.
Then the test... When it came down to testing the setup to make sure it was working, I must admit feeling a little bit nervous about pulling the plug to see what would happen. However, it was actually kind of fun when you think about it. Living on the edge by closing my eyes tight and ripping out the plug. There we go, I did it. The master-slave setup went fine, enough power for two machines continuing for nearly fiftteen minutes. Then the automatic shutdown, beep-beep, and the power off sequence. Truly amazing. Put the plug back, the UPS beeped alive and the two machines rebooted perfectly. Just as if nothing had ever happened.
