1. Unboxing & Cabling
Hardware Setup:
├── WAN → Modem/Router (2.5G for max speed)
├── LAN1 → Management PC (initial setup)
├── LAN2-4 → Switch/APs (PoE powered)
└── Power → 45W USB-C adapter (EU plug included)2. First Boot & Adoption
Browser → ethernet.ui.com → "Adopt Device"
→ UniFi OS 4.1.x loads automatically (5-7 min)
→ Create account → Set up site ("Zurich-Home")3. Basic Configuration (Network App)
Recommended First Steps:
1. VLANs: 10=Guest, 20=IoT, 30=Corporate
2. Firewall: Guest isolation ON, IoT → block internet
3. WiFi: WPA3, band steering, MLO (WiFi 7)
4. Protect/Access: Install apps (2 GB SSD)Config Example (JSON Export):
{
"networks": [{
"vlan": 10,
"name": "Guest",
"isolate": true,
"dhcp_range": "192.168.10.100-250"
}]
}Hands-On Review: 4-Week Test from Zurich
Test Setup: 1x UCG Ultra + 3x U7 Pro APs + 4x G5 Turret cameras + 45 clients (iPhones, PCs, smart home). Usage: home office, 4K streaming, Protect recording (2 TB cloud).
