If the conductors in each cable touch one another, the system SHOULD read that as a shorted cable and ignore it.
BUT, you should know that you stand a very good chance of being put in the trick bag if anything ever goes wrong with their IT system. Write down exactly how you are going to deal with your end of the cables and officially hand it to them so they can't later say that hey had no knowledge of what you were up to.
As I said before, I fervently believe that the majority of IT folks are clueless and are just itching for a chance to blame someone else for their system woes.
I had one of our IT staff try to fix a computer problem last week; and a lot of her time was spent opening various windows muttering, "What's this one do? Let's try this setting. Let's 'google' it and see if anyone else knows how to fix this." ... followed by "I'm going to get him a better program, this Microsoft program isn't the best" when there are only a few of us in a thousand user network with this issue. If it was a bad piece of software, wouldn't it be acting the same on ALL of the machines throughout the company?
If we go out on a call and there's no power on the load side of a transformer how many of us would install a new Service at a different voltage? I dare say that we would at least try to find the blown fuse or failed transformer before we ripped out the whole electrical system and replaced it with a something different.
Keep in mind, these people invented the concept of "reboot". Their first instinct to a problem is to turn it off and on and see if the problem goes away...their second instinct is to blame someone else.
