Who, Me? G’day readers, and welcome as soon as once more to The Register’s reader-submitted column of chilly consolation that we name Who, Me? the place you discover out that everybody – even intelligent clogs such as you – makes errors.
This week, meet a hero we’ll Regomize as “Mick” who labored for “a big Aussie telco” within the Nineties (a time when there weren’t precisely a plethora of enormous Aussie telcos, in order that narrows it down a bit).
One advantageous day Mick discovered himself having to go out to someplace between the Queensland cities of Mt Isa and Townsville. For the unfamiliar, a lot of the 900kms between the cities presents is sizzling desert famed for its warmth, crimson mud, and deadly nastiness.
The unstaffed phone trade on this distant location required the set up of two 16-amp rack-head fuses on its 50 volt major energy cables. Mick notes that this was an uncommon requirement, as gear racks normally solely wanted one fuse. However on this case the gear was significantly energy hungry – thus the 2.
The opposite trick was that the set up needed to be completed whereas the ability was dwell. It was, in spite of everything, a phone trade, so shutting it down for any size of time would symbolize a terrific ache within the proverbial.
The cables, and thus the fuses, have been mounted to the metal framework above the racks. As a cautious electrician, Mick naturally insulated all the metal with plastic wrap to keep away from mishaps. The set up of the primary fuse proceeded completely.
Sadly (you knew there needed to be an “sadly”) he made the error of connecting the fuse to the earth cable on the rack – a size on uninsulated braided stainless-steel cable about 5mm in diameter. When he began to put in the second fuse, the braided cable “shorted to the optimistic pole” as Mick instructed Who, Me?
What meaning, for these unfamiliar with sparkie jargon, is that there was an almighty flash and bang because the earth cable immediately vaporized. It additionally blew the principle 100 amp fuse – reducing energy to your entire trade.
Bear in mind how we did not wish to do this?
Panic set in, as Mick began frantically looking for a alternative fuse. Inside a couple of minutes he had discovered one and reinstalled it, then waited because the trade regularly got here again on-line. Just a few issues needed to be manually reset.
All that remained was to complete the job he was there to do and head again to Townsville.
Solely when he bought again to house base there was dialogue of this mysterious telephone outage that had taken out all telephone visitors west from roughly the place Mick had simply been all the best way to Darwin within the Northern Territory – 1,600kms up the highway from Mt Isa. No-one might clarify fairly what had occurred or how. Mick, in his knowledge, joined in on the dumbstruck hypothesis.
To this present day he is fairly positive no-one is aware of what actually occurred.
