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
- 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.
- 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%).
- 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.
- 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.
- 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.
- 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.
- 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.
