Category 6A structured cabling and new power circuits for a co-location room

The room had grown outside its design

Within 420 m² four generations of installation lived together: a 1998 board feeding improvised rack outlets, data cables crossing the power tray, and two UPS units with expired batteries the operations team already treated as decoration. Every new asset came in through a tap-off, never through a design — and the label tags had more splices than numbers.

Functional principle and separation

What NBR 14565 asks and site work usually ignores

• Three cabling spaces in cascade: the carrier entrance, the main room and floor distribution, each with its own route
• Distance and physical separation between twisted-pair cable and power circuits, respecting size and tap-offs
• Earthing to a single reference mesh, with an equipotential bar along each rack row
• Alphanumeric identification at both ends with a register sheet, no abbreviation invented by the installer

1. Two independent power boards, one per feed, with type B RCDs and consumption metering per rack row
2. Full UPS replacement with runtime sized from real measured load in the rack, not from an estimate
3. 96 Category 6A outlets on 1U patch panels, laid out by functional principle and tested link by link
4. Migration across three overnight windows, with the new cabling commissioned before the old one went dark
