Remembering ALL the vital things to go on ups.
I got a nice big ups at home, external batteries for about 5 hrs runtime at full load, powering my proliant server & network kit. Our utility announced a maintenance outage. No problem, been there, done that, i power down the unneccessary stuff before heading to work that day, and monitor the situation remotely. About an hour into the outage the proliant goes down. ILO tells me its having a heatstroke. Whoopsie, i forgot the cooling air fan; the server is a bit noisy, so after complaints from the missus it sits in a silencing cabinet, therefore requiring external forced air to keep it running. And i forgot to put the fan on the ups circuit. Thank you ILO, after the power came back i could power it on remotely. And rewired the fan after i got home. Lesson learnt.
