LT-ASG1622V 16+2+2 Port Gigabit Unmanaged PoE Switch
The LT-ASG1622V is an advanced unmanaged PSE PoE switch from NEWBRIDGE® designed for large surveillance and enterprise networks requiring high power, Gigabit speeds, and flexible uplinks with a 4‑position DIP switch for extended functionality. It features 16× 10/100/1000Mbps Gigabit PoE ports (IEEE 802.3af/at, up to 30W per port), 2× 10/100/1000Mbps Gigabit uplink RJ45 ports, and 2× 1000Mbps SFP slots – all 20 ports work simultaneously.
With a total PoE budget of 300W, built‑in intelligent PoE priority mechanism, watchdog (AI self‑healing) on ports 1‑16 (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 1‑16 to 10Mbps), and VLAN isolation mode (isolates ports 1‑16 from each other while keeping communication with uplink ports).
Housed in a fanless galvanized steel metal case (19″ rack‑mount size), this plug‑and‑play switch is ideal for large‑scale IP surveillance, Wi‑Fi AP deployments, campus networks, hotels, and industrial environments where high port density, high PoE power, and dual fiber uplinks are required.
Key Features
🔌 High‑Power Gigabit PoE+ with 300W Budget, Priority & Protections
16× Gigabit PoE ports – IEEE 802.3af/at compliant, up to 30W per port, total PoE budget 300W.
Intelligent PoE priority mechanism – ensures critical ports stay powered when power budget is low.
OVP (Over Voltage Protection) and short‑circuit protection for maximum safety.
4KV lightning protection on both PoE ports and power supply.
🔁 AI Self‑Healing Watchdog (Ports 1‑16)
Continuously monitors data communication on all 16 PoE ports.
If a connected device stops working for 2 minutes, the corresponding port automatically restarts – no manual intervention.
Enabled via DIP switch position 3 (AI self‑healing mode).
🌐 Dual Gigabit Uplink & Dual SFP Slots (Fixed 1000Mbps)
2× 10/100/1000Mbps RJ45 uplink ports for high‑speed connection to NVRs or core switches.
2× 1000Mbps SFP slots – fixed Gigabit fiber uplink, compatible with standard 1.25G SFP modules (multi‑mode or single‑mode).
📡 Four‑Function DIP Switch
The 4‑position DIP switch provides easy configuration:
Position 1 (Long Range): ON = ports 1‑16 reduce to 10Mbps, transmission distance up to 250 meters.
Position 2 (VLAN): ON = isolates ports 1‑16 from each other (they only communicate with uplink ports 17‑18).
Position 3 (AI Self‑Healing): ON = enables watchdog auto‑restart on ports 1‑16.
Position 4 (Reserved): Unused; keep OFF.
⚡ High‑Performance Switching
Switching capacity: 40Gbps; throughput: 59.52Mpps; MAC table: 8K; packet buffer: 4M.
8‑core PoE power supply (pins 1,2,3,6 + and 4,5,7,8 -) for stable delivery.
Store‑and‑forward, wire‑speed forwarding, IEEE 802.3x flow control.
🔌 Plug‑and‑Play & Reliable Hardware
No IP/web configuration; all extended features via 4‑position DIP switch.
Fanless silent design, galvanized steel case, 19″ rack‑mount dimensions (440×192×45mm).
Operating temperature: 0℃~55℃; storage: -40℃~70℃.
