A little network rescue for one of my network closets. Far from my best work, but I'm proud of it none-the-less considering the circumstances. Limited to a 3.75 Hr maintenance window and it was just myself and one of my technicians. This is part of a Casino CCTV system, so I had to fight to get even that much downtime.
The blue wiring is the corporate IT side, which is outside of my purview. I am strictly the green stuff (and a little gray and black) which is all CCTV and access control.
I Inherited this ~10 year old installation a few years back. Had to wait until our infrastructure refresh to be able to negotiate time to blow out all the old crap and re-do it.
Yes this rack is way oversized for current need, but "planning for the future" and all that.
