- 1 × 10/100 Mbps uplink port (data only)
- 12 V DC output jack for powering an ONU/ONT downstream
🛠️ Key Technical Specs
- Standards: IEEE 802.3, 802.3u, 802.3x, 802.3az (Energy Efficient Ethernet)
- MAC table: 1K entries; packet buffer: ~448 Kb
- Max packet size: 1,536 bytes
- Throughput:
- 100 Mbps ports → 148,800 pps
- 10 Mbps ports → 14,880 pps
⚡ Power Management & Protection
- Powered remotely via 24 V DC PoE injector (0.75–1 A) — no rooftop UPS needed
- 2500 V surge protection on all ports
- Over-voltage protection (handles up to ~50 V DC, shuts down and auto-recovers removal)
- Per-port over-current protection via resettable fuses
🌡️ Physical & Environmental Specs
| Attribute | Specification |
|---|---|
| Power consumption | ~2 W (switch) + ~5 W (injector) |
