4. Product Overview
The VIMIN 16-Port 2.5G PoE Switch is designed for high-speed network environments, offering robust performance and Power over Ethernet capabilities.
4.1 Key Features
- High-Performance PoE+ 2.5G: Equipped with 16 RJ45 PoE+ ports (100/1000/2500 Mbps) and 2x 10 Gigabit SFP ports for seamless data transfer with 2.5 Gbps NAS, wireless access points (APs), and PCs.
- Robust PoE+ Functionality: Supports IEEE 802.3af/at standards, delivering up to 30W per port with a total PoE power budget of 220W. This allows powering compatible devices without separate power adapters. Note: This switch does not support passive PoE.
- 120Gbps Switching Capacity: Provides super data processing capabilities for efficient network operation.
- One-Touch VLAN: Isolate ports 1-16 while maintaining communication with SFP ports to enhance network security, monitor network interruptions, reduce interference, and optimize port bandwidth utilization.
- 6KV Surge Protection and Fanless Design: Integrated 6KV surge protection safeguards devices from electrical surges. The fanless design ensures silent operation.
- Plug and Play: As an unmanaged switch, it requires no complex configuration, offering easy installation and immediate use.
- Durable Metal Housing: Constructed with a robust metal casing for enhanced durability and heat dissipation.

4.3 Rear Panel Layout
The rear panel typically contains the power input and grounding screw (if applicable). Ensure the power cable is securely connected to the power input port.
5. Setup
5.1 Physical Installation
- Placement: Place the switch on a stable, flat surface or install it into a standard 19-inch rack using the provided mounting brackets. Ensure adequate space around the switch for proper airflow.
- Power Connection: Connect the power cable to the switch's power input and then to a suitable power outlet.
- Grounding (Optional): For enhanced safety, connect a grounding wire to the grounding screw on the switch (if present) and to a proper ground source.

5.2 Connecting Network Devices
As an unmanaged switch, the VIMIN 16-Port 2.5G PoE Switch is plug-and-play. Simply connect your devices:
- Connect your network devices (e.g., computers, NAS, access points, IP cameras) to the RJ45 PoE+ ports using standard Ethernet cables.
- For high-speed uplinks or fiber connections, insert compatible SFP+ modules (not included) into the 10G SFP+ slots and connect fiber optic cables.
- The switch will automatically detect the connected devices and establish network links. For PoE-compatible devices, power will be supplied automatically.

6. Operating Instructions
6.1 Basic Operation
Once powered on and devices are connected, the switch operates automatically. The LED indicators will provide status information:
- A solid Link/Act LED indicates a stable network connection.
- A blinking Link/Act LED indicates data activity.
- A solid 2.5Gbps Link LED indicates a 2.5Gbps link speed.
- A solid PoE LED indicates that power is being supplied to the connected PoE device.
6.2 VLAN Mode
The switch features a one-touch VLAN mode. When enabled, this mode isolates ports 1-16 from each other, preventing direct communication between them. However, all isolated ports can still communicate with the SFP uplink ports. This feature is useful for:
- Enhancing network security by segmenting traffic.
- Monitoring network interruptions more effectively.
- Reducing broadcast storms and optimizing bandwidth.
To activate or deactivate VLAN mode, use the physical VLAN switch located on the front panel of the device.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the switch. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure that the cooling vents on the sides of the switch are not obstructed to maintain optimal operating temperature. The fanless design relies on natural convection.
- Environmental Conditions: Operate the switch within the specified temperature range of 0°C to 45°C (32°F to 113°F).
- Firmware Updates: As an unmanaged switch, firmware updates are generally not required or available.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to the switch. | Power cable disconnected or power outlet faulty. | Check power cable connection. Test the power outlet with another device. |
| No link light on a connected port. | Faulty cable, incorrect cable type, or connected device is off/faulty. | Ensure the Ethernet cable is properly connected and not damaged. Verify the connected device is powered on and functioning. Try a different port or cable. |
| PoE device not receiving power. | Device is not PoE compatible, exceeds PoE budget, or faulty cable. | Confirm the device supports IEEE 802.3af/at PoE. Check the total power budget (220W) and individual port limit (30W). Use a known good Ethernet cable. |
| Network performance issues (slow speed). | Cable quality, network congestion, or VLAN mode misconfiguration. | Ensure high-quality Ethernet cables are used (Cat5e or better for 2.5G). Check for excessive network traffic. Verify VLAN mode setting is appropriate for your network setup. |
