How to Use 9 Port DIN POE++ Switch with 10gb SFP+: Examples, Pinouts, and Specs

The TrendNet TI-BG5091 is an industrial-grade network switch designed to deliver both power and data connectivity to networked devices. Equipped with 9 Gigabit PoE++ ports and a 10Gb SFP+ slot, this switch is ideal for high-performance networking in environments requiring robust and reliable connections. Its Power over Ethernet (PoE++) capability allows it to power devices such as IP cameras, VoIP phones, and wireless access points, eliminating the need for separate power supplies.

• Surveillance Systems: Powering and connecting IP cameras in industrial or outdoor environments.
• Wireless Networks: Providing data and power to wireless access points.
• VoIP Systems: Supporting VoIP phones in office or industrial setups.
• Industrial Networking: Connecting and powering devices in factories, warehouses, or other rugged environments.
• High-Speed Fiber Connectivity: Utilizing the 10Gb SFP+ port for long-distance, high-speed data transfer.

1. Powering the Switch:

   • Connect a 48-56V DC power supply to the terminal block on the switch.
   • Ensure the power source meets the required voltage and current ratings.

2. Connecting Devices:

   • Use Ethernet cables to connect PoE-compatible devices (e.g., IP cameras, access points) to the PoE++ ports (1-8).
   • For non-PoE devices, use the standard Gigabit Ethernet port (port 9).

3. Fiber Connectivity:

   • Insert a compatible 10Gb SFP+ module into the SFP+ slot.
   • Connect the fiber optic cable to the SFP+ module for high-speed data transfer.

4. Mounting:

   • Use the included DIN-rail or wall-mount brackets to securely install the switch in the desired location.

• PoE Power Budget: Ensure the total power consumption of connected devices does not exceed the 360W PoE power budget.
• Cable Quality: Use high-quality Cat5e or Cat6 cables for optimal performance and to minimize signal loss.
• Environmental Conditions: Operate the switch within the specified temperature range (-40°C to 75°C) to avoid damage.
• SFP+ Module Compatibility: Use TrendNet-certified SFP+ modules for guaranteed compatibility and performance.

To connect an Arduino UNO to the TI-BG5091 for network communication, you can use an Ethernet shield. Below is an example Arduino sketch for basic communication:

#include <SPI.h>
#include <Ethernet.h>

// MAC address and IP address for the Arduino
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 177);

// Initialize the Ethernet server on port 80
EthernetServer server(80);

void setup() {
  // Start the Ethernet connection
  Ethernet.begin(mac, ip);

  // Start the server
  server.begin();
  Serial.begin(9600);
  Serial.println("Server is ready at IP: ");
  Serial.println(Ethernet.localIP());
}

void loop() {
  // Listen for incoming clients
  EthernetClient client = server.available();
  if (client) {
    Serial.println("New client connected");
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        Serial.write(c); // Echo data to Serial Monitor
        // Respond to the client
        client.println("Hello from Arduino!");
      }
    }
    client.stop();
    Serial.println("Client disconnected");
  }
}

1. No Power to Connected Devices:

   • Cause: Insufficient power supply or exceeded PoE power budget.
   • Solution: Verify the power supply voltage and ensure the total power consumption of connected devices is within the 360W limit.

2. No Network Connectivity:

   • Cause: Faulty cables or incorrect port connections.
   • Solution: Check all Ethernet cables and ensure devices are connected to the correct ports.

3. SFP+ Module Not Detected:

   • Cause: Incompatible or improperly seated SFP+ module.
   • Solution: Use a TrendNet-certified SFP+ module and ensure it is securely inserted.

4. Overheating:

   • Cause: Operating outside the specified temperature range.
   • Solution: Install the switch in a well-ventilated area within the -40°C to 75°C range.

• Q: Can I use this switch with non-PoE devices?

  • A: Yes, the switch supports non-PoE devices via the standard Gigabit Ethernet port or PoE++ ports without supplying power.

• Q: What type of SFP+ modules are compatible?

  • A: TrendNet-certified 10Gb SFP+ modules are recommended for optimal performance.

• Q: Is the switch suitable for outdoor use?

  • A: While the switch is designed for industrial environments, it should be housed in a weatherproof enclosure for outdoor use.

• Q: Can I daisy-chain multiple switches?

  • A: Yes, you can use the 10Gb SFP+ port to connect multiple switches for extended networks.
