The comms room had grown by accretion over six years — no labelling, no slack management, and a patch field nobody was willing to touch in case something went dark.
We rebuilt both racks over a weekend to avoid downtime. Every run was re-terminated, tested and labelled at both ends, then dressed into proper cable management. Camera, guest and corporate traffic were split onto separate VLANs, which had been a standing audit finding.
The client received a port-by-port schedule as a PDF. Their own IT team now handles moves and changes without calling us.
