Tier 1 — RG-NBS3100. Layer 2 cloud-managed, VLANs + IGMP snooping, 370W PoE+ and 56 Gbps on the 24-port model. The workhorse for most 8–48 camera sites.

Six-step commissioning order on a Hub 2 Plus retrofit:
1. Push hub to OS Malevich 2.13+
2. Mount MultiTransmitter beside the legacy panel
3. QR-code pair from the Ajax PRO app
4. Terminate zones (1.5 mm² alarm cable)
5. Set R, 2R, 3R resistors per zone
6. Walk + ARC handover
Compatibility gate: Hub Plus, Hub 2 (2G/4G), Hub 2 Plus (2G/4G), Superior Hub Hybrid (2G/4G) — all on OS Malevich 2.13+. Older Hub (gen 1) and ocBridge Plus / uartBridge are out.
2EOL + 3EOL require MultiTransmitter firmware 2.13.0+. 4/6
