Design order that avoids rework
- Map the physical process and where devices live
- Place MDF and IDFs based on distance limits, not convenience
- Run fiber between closets and buildings
- Define VLANs by function and write inter-VLAN policy
- Design Wi-Fi along aisles for handheld radios
- Plan redundancy for internet and core switching
- Specify labeling and documentation standards up front
- Validate with loaded racks before signing off
