Commission new stores end to end — rack layout, structured cabling, router/firewall and managed switch configuration, VLAN segmentation (management / POS & token / IoT machines / CCTV / staff), access point setup, WireGuard tunnel back to HQ, Zabbix agent registered.
Bring the machine layer online — wire and address washer/dryer controllers, verify RS485/Modbus TCP connectivity, pull and run the Docker container for the IoT service, confirm the FastAPI endpoint is reachable and returning correct machine state, and prove each machine reads and writes before handover.
Diagnose faults to root cause — machines become offline, a token terminal drops off, a store loses its tunnel. You isolate it layer by layer (cable → link → IP → VLAN → route → firewall → service → application) and document what it actually was.
