LT-AS2422GV 24+2+2 Port Unmanaged PoE Switch
The LT-AS2422GV is an unmanaged PSE PoE switch from NEWBRIDGE® designed for large surveillance and enterprise network applications. It features 24× 10/100Mbps 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 28 ports work simultaneously.
With a total PoE budget of 300W, built-in intelligent PoE priority mechanism, watchdog on ports 1‑24 (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 1‑24 to 10Mbps), and VLAN isolation mode (isolates ports 1‑24 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 large‑scale deployments such as campuses, hotels, warehouses, and enterprise networks where high PoE power and fiber uplink flexibility are required.
Key Features
🔌 High‑Power PoE+ with 300W Budget, Priority & Protections
IEEE 802.3af/at compliant (up to 30W per port), total PoE budget 300W – ample power for up to 24 devices.
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 1‑24)
Continuously monitors data communication status on all 24 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.
🌐 Dual Gigabit Uplink & Dual SFP Fiber Slots
2× 10/100/1000Mbps RJ45 uplink ports for high‑speed connection to NVRs or core switches.
2× 1000Mbps SFP slots – allow fiber uplink (multi-mode or single-mode, distance up to 100km depending on module), providing flexible long-distance backbone connectivity and redundancy.
📡 Long‑Range & VLAN Mode (DIP Switch)
Long-Range Mode: Reduces ports 1‑24 to 10Mbps, extending transmission distance up to 250 meters over standard Cat5e/6 cable – ideal for large‑area surveillance.
VLAN Mode: Isolates ports 1‑24 from each other (they only communicate with uplink ports 25‑26), reducing broadcast storms and preventing DHCP conflicts.
⚡ High‑Performance Switching
24× 10/100Mbps PoE ports + 2× Gigabit RJ45 uplink + 2× Gigabit SFP, all support non-blocking wire-speed forwarding.
