LT-ASG2422V   24+2+2 Port Gigabit Unmanaged PoE Switch

The LT-ASG2422V is an unmanaged PSE PoE switch from NEWBRIDGE® designed for large‑scale surveillance and enterprise networks requiring high port density, Gigabit speeds, and flexible fiber uplinks. It features 24× 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 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 (19″ rack‑mount size), this plug‑and‑play switch is ideal for large IP surveillance systems, Wi‑Fi AP deployments, campus networks, hotels, and enterprise access layers.

Key Features

🔌 High‑Power Gigabit PoE+ with 300W Budget, Priority & Protections

• 24× 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.

🔁 Watchdog Auto‑Recovery (Ports 1‑24)

• Continuously monitors data communication on all 24 PoE ports.

• If a connected camera or device stops working for 2 minutes, the corresponding port automatically restarts – no manual intervention needed.

🌐 Dual Gigabit Uplink & Dual SFP Slots

• 2× 10/100/1000Mbps RJ45 uplink ports for high‑speed connection to NVRs or core switches.

• 2× 1000Mbps SFP slots – allows fiber uplink (multi-mode or single-mode, distance up to 100km depending on module), providing flexible long-distance backbone connectivity.

📡 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.

• 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× Gigabit PoE ports + 2× Gigabit uplink + 2× Gigabit SFP, all support non-blocking wire-speed forwarding.

• Switching capacity: 56Gbps; throughput: 41.664Mpps; MAC table: 4K; packet buffer: 2M.

• 8‑core PoE power supply (pins 1,2,3,6 + and 4,5,7,8 -) for stable delivery.

• 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℃.
