The Ubiquiti UniFi SmartPower Cable (Model: USP-Cable) is a proprietary DC power interlink engineered to pair UniFi networking devices—such as Enterprise/Pro PoE switches and Dream Machine Gateways—with the UniFi SmartPower System (USP-RPS). Designed to provide high-capacity DC power delivery, the USP-Cable acts as the physical conduit for secondary power redundancy, preventing network dropouts in the event of an internal power supply failure or primary AC source loss.
Built to transport continuous high-amperage current, the cable incorporates a multi-conductor core featuring (18) 16 AWG power conductors paired with (6) 24 AWG signal and control conductors. The core uses high-conductivity tinned copper wire with 0.35 mm PVC insulation and a UV-resistant outer PVC jacket measuring 9.5 \times 23.0\text{ mm}. The cable features latching proprietary connectors at each end to guarantee secure, vibration-resistant seating with automatic detection in the UniFi Controller platform.
Comprehensive Key Features:
Proprietary SmartPower DC Interface: Custom latching connectors engineered specifically for seamless lock-in engagement with USP-RPS ports and UniFi target hardware.
High-Current Multi-Conductor Wire Gauge: Utilizes (18) 16 AWG conductors for high-wattage DC delivery alongside (6) 24 AWG conductors for control telemetry.
Instant Failover Power Support: Transports 52\text{V DC} and 11.5\text{V DC} power output directly to connected switches and gateways.
1.5 Meter Reach: Flexible 1.5 m (4.9 ft) length accommodates standard 19" rack layouts and top-of-rack or middle-of-rack power backup arrangements.
Tinned Copper Construction: Tinned copper conductors minimize resistance and oxidation while ensuring heat-dissipating performance during maximum load backup.
Plug-and-Play Integration: Automatically recognized by the UniFi Network Controller platform for real-time status diagnostics and power monitoring.
