LT-AS0820GV 8+2 Port Unmanaged PoE Switch (Gigabit Uplink)
The ND-S0820GV is an unmanaged PSE PoE switch from NEWBRIDGE® designed for small to medium surveillance and network applications. It features 8× 10/100Mbps PoE ports (IEEE 802.3af/at, up to 30W per port) and 2× 10/100/1000Mbps Gigabit uplink ports – all 10 ports work simultaneously. With a total PoE budget of 120W, built‑in intelligent PoE priority mechanism, watchdog on ports 1‑8 (auto‑restarts unresponsive devices after 2 minutes), OVP (Over Voltage Protection), short‑circuit protection, 4KV lightning protection on both ports and power supply, 250‑meter long‑range transmission (reduces ports 1‑8 to 10Mbps), and VLAN isolation mode (isolates ports 1‑8 from each other while keeping communication with uplink ports). Housed in a fanless galvanized steel metal case, this plug‑and‑play switch is ideal for IP cameras, VoIP phones, and wireless APs in offices, hotels, and small business networks where Gigabit uplink speed is needed.
Key Features
🔌 PoE+ with 120W Budget, Priority & Protections
IEEE 802.3af/at compliant (up to 30W per port), total PoE budget 120W.
Intelligent PoE priority mechanism – when remaining power is low, high‑priority ports are guaranteed power to prevent overload.
OVP (Over Voltage Protection) – safeguards the switch and connected devices from voltage spikes.
Short‑circuit protection built‑in for safe operation.
4KV lightning protection on both PoE ports and power supply.
🔁 Watchdog Auto‑Recovery (Ports 1‑8)
Continuously monitors data communication status on all 8 PoE ports.
If a connected camera or device stops working for 2 minutes, the corresponding port automatically restarts to restore operation – no manual intervention needed.
🌐 Gigabit Uplink Ports
Two 10/100/1000Mbps uplink ports provide high‑speed connection to NVRs, routers, or core switches, eliminating bottleneck.
📡 Long‑Range & VLAN Mode (DIP Switch)
Long‑Range Mode: Reduces ports 1‑8 to 10Mbps, extending transmission distance up to 250 meters over standard Cat5e/6 cable.
VLAN Mode: Isolates ports 1‑8 from each other (they only communicate with uplink ports 9‑10), reducing broadcast storms and preventing DHCP conflicts.
⚡ High‑Performance Switching
8× 10/100Mbps PoE ports + 2× Gigabit uplink ports, all support non‑blocking wire‑speed forwarding.
Switching capacity: 5.6Gbps; throughput: 4.1664Mpps; MAC table: 2K; packet buffer: 1M.
Supports IEEE 802.3x flow control and backpressure.
🔌 Plug‑and‑Play & Reliable Hardware
No configuration required. LED indicators for power (PWR), link (Link), PoE status, and extend mode.
Fanless silent design, galvanized steel metal shell, excellent heat dissipation.
Operating temperature: 0℃～55℃; storage: -40℃～70℃.
