Monalogg ML-24G22GS-400W 28 Port Long-range Gigabit Intelligent PoE Switch

The ML-24G22GS-400W is a 28-port Gigabit PoE switch designed for small to medium deployments, offering a blend of power, flexibility, and reliability. Here’s a structured overview of its key features and considerations:

Key Features

1. Port Configuration:
   • 24× PoE+ Ports: Ports 1-24 support IEEE 802.3af/at (15.4W/30W), with Port 1 capable of 60W output (beyond 802.3at, possibly proprietary).
   • 2× Gigabit Uplink RJ45 Ports: For high-speed copper connections.
   • 2× SFP Ports: Fiber uplink support (IEEE 802.3z) for long-distance connectivity.
2. PoE Power Budget:
   • Total Budget: 400W.
   • Prioritization: Ports 1-16 prioritized for PoE power by default.
   • Usage Monitoring: LED indicators for power usage (Green: <90%, Flashing: 90–95%, Solid: 95–100%).
3. Extend Mode:
   • Ports 17–24: Drop to 10Mbps with 250-meter reach when enabled (via DIP switch).
   • PoE Watchdog: Enhanced monitoring for connected devices in this mode.
4. Performance:
   • Non-Blocking Throughput: 56Gbps switching capacity.
   • Packet Forwarding Rate: 41.644 Mpps (line-rate for all ports).
   • Store-and-Forward Transmission: Ensures data integrity.
5. Durability & Safety:
   • Surge/ESD Protection: 4kV common mode, 2kV differential mode; 8kV air/6kV contact ESD.
   • Fanless Design: Silent operation but limited to 0–40°C environments.
6. Ease of Use:
   • Zero Configuration: Plug-and-play for basic setups.
   • LED Indicators: Port status (link/speed), PoE power, and mode monitoring.
   • DIP Switch: Toggles between Default (all ports at 1G) and Extend modes.
7. Physical Design:
   • Compact Form Factor: 440mm width (rack-mountable with optional brackets).
   • Lightweight: 2.86kg (desktop or rack installation).

Use Cases

• IP Cameras & Wireless APs: Port 1’s 60W supports high-power devices (e.g., PTZ cameras).
• Long-Distance Deployments: Extend mode for warehouses or outdoor setups.
• Small Office Networks: Combines PoE, fiber uplinks, and surge protection for reliability.

Considerations

• PoE Budget Planning:
  • Port 1 (60W) + 7× 30W ports = 270W (within 285W limit). Avoid overloading.
• Speed Trade-off: Extend mode sacrifices speed (10Mbps) for distance on ports 17–24.
• Temperature Sensitivity: Fanless design requires ambient temps ≤40°C.
• Unmanaged Features: No advanced QoS/VLAN; ideal for simple deployments.

Package Contents

• Switch, power cord, manual, and qualification certificate.

Summary: A cost-effective, versatile PoE switch for powering and connecting devices in environments requiring basic management, extended reach, and robust surge protection. Ideal for SMBs, surveillance, and IoT deployments.
