What you'll learn
- Describe a building network in layers, divide responsibilities between the installer and the owner's network team, and troubleshoot from the bottom up
- Explain Ethernet frames, MAC addresses, copper and fiber Ethernet types and auto-negotiation, and recognize speed fallbacks and duplex mismatches
- Explain how switches learn and forward, and use VLANs, access and trunk ports and the MAC address table to place and locate devices
- Convert addresses between decimal, binary and hexadecimal, calculate subnets, and read an IP plan to check a device's address, mask and gateway
- Explain DHCP, DNS, gateways and time services, size a DHCP scope, and set fixed addresses from the plan
- Apply PoE types and classes, calculate switch power budgets and cable losses, and follow guidance on bundle heating
- Mount, connect, power and verify wireless access points according to the design, including Wi-Fi 6, 6E and 7 port and power needs
- Connect, configure and prove cameras, door controllers, phones, displays and sensors in their own systems
- Mount network equipment, provide redundant power, patch from the port map and keep complete network records
- Test connectivity with network testers and ping, read switch counters, and hand faults to the network team with clear evidence
- Apply defensive security habits: credentials, firmware, network separation, physical security and confidentiality of records
- Plan, commission and hand over a floor of PoE devices with application and resilience tests and a complete record
