Start with the physical sites, user and device counts, traffic patterns, security zones and availability requirements. These determine the switching, routing, wireless and infrastructure components required.
Core bill-of-material categories
- Core, distribution and access switches with port and PoE requirements
- Routers, gateways, wireless controllers and access points
- Optical modules, transceivers, fibre and copper patching
- Racks, cable management, power distribution and UPS systems
- Licences, subscriptions, support and spare units
- Mounting kits, power supplies and region-specific power cords
Check compatibility before purchase
Validate interface speeds, optics standards, PoE budgets, stacking support, software versions and licensing terms. Manufacturer part numbers should be recorded wherever possible.
Include deployment assumptions
Record quantities by site, required delivery phases and acceptable substitutions. A precise schedule helps suppliers propose workable lead times and alternatives.
