Finally, a wafer-thin server... Only a tiny little thin one. Oh all right. Just the one...

Not blown one up, but it helps if they are live....

Following a planned power off for electrical work, 06fartooearly on a Monday, I come in, fire up all the network kit, lights come on in the right order, everything goes green as it should, lovely. Go to the server cabinet, start them all up, all the usual whirry noises, fans, lights, etc. Fantastic. Then my ears pick up a regular beeping noise, one not normally heard. WTF?? While my half awake brain processes this, all the servers shut down and there is silence again. Mild panic ensues. Press power again, nothing. Beeping continues. Finally look at UPS at the bottom of the rack....oh-oh, red lights all round. No power. Phone electrician on call...…

After the inspection one of the RCDs hadn't been replaced correctly, so the entire rack had no power. All the servers fired up on UPS power, which then promptly shut them all down gracefully before it ran out of battery power.

Lesson learned, check everything for red lights. Even the stuff right at the bottom...….
