YADM ... Yet Another Doh Moment ...
I had recently managed moving our Siemens PBX, Telephony servers & call centre servers into a shiny new server room. I had purchased a network card for the system's UPS so we I could monitor it along with all the other services (knowing something is misbehaving 30 seconds before the users being a Good Thing (tm)).
So I rang the suppliers techies and quized them on procedure, did the change thing, as no downtime was needed I proceded on a Monday morning with a Sunday hangover. I put the UPS in to pass-thru mode prior to fitting the card ... Ker-Thump!!! ... both racks went down. It took me most of the day to recover everything.
Basically our sparkies had not wired in the pass-thru. I was quized by the IT Director and the Finance Director and while they agreed the outage was not my fault I was unfortunately the PM on the system move so I should have checked the sparkies work. Obviously the dept thought it was hilarious.
A bad day ended better, went to the pub.
Biting the hand that feeds IT
