Experiment - 80 :- To demonstrate the functionality of Power over Ethernet (PoE) and measure its performance in powering a device over an Ethernet cable.

Aim :-  To demonstrate the functionality of Power over Ethernet (PoE) and Measure its performance in powering a device over an Ethernet cable.

Materials Needed

1. PoE Injector or PoE Switch: To provide power over the Ethernet cable.
2. PoE-Compatible Device: Such as a PoE IP camera, VoIP phone, or a PoE splitter.
3. Ethernet Cables: At least two Cat5e or Cat6 cables.
4. Multimeter: To measure voltage and current.
5. Network Switch (optional): If using a PoE injector.
6. Computer or Laptop: For monitoring and configuration (if necessary).
7. Power Source: For the PoE injector or switch.

Experiment Steps

Step 1: Setup the Equipment

Connect the PoE Injector/Switch:

• If using a PoE injector, connect it to a power source and plug it into your network.
• If using a PoE switch, ensure it is powered and connected to your network.

Connect the PoE Device:

• Use an Ethernet cable to connect the PoE output port of the injector/switch to the PoE-compatible device.

Connect the Data Input:

• If using a PoE injector, connect another Ethernet cable from the data input port of the injector to your network switch or router.

Step 2: Power On the Equipment

1. Turn on the PoE Injector/Switch: Ensure that the device is powered on and functioning.
2. Check the PoE Device: Verify that the PoE device powers on, indicating that it is receiving power through the Ethernet cable.

Step 3: Measure Voltage and Current

1. Use a Multimeter: Set the multimeter to measure DC voltage.
2. Measure Voltage: Connect the multimeter probes to the appropriate pins on the Ethernet cable (typically pins 1, 2 for data and 3, 6 for power in 802.3af/at standards).
3. Record the Voltage: Note the voltage reading.
4. Measure Current: If possible, measure the current flowing through the cable using the multimeter in series with the load.

Step 4: Test Data Transmission

1. Connect a Computer: If applicable, connect a computer to the same network to test data transmission.
2. Ping Test: Use the command prompt to ping the PoE device to ensure it is reachable over the network.
3. Monitor Performance: Check for any data loss or latency issues.

Step 5: Analyze Results

1. Evaluate Power Delivery: Compare the measured voltage and current against the specifications of the PoE standard being used (802.3af, 802.3at, or 802.3bt).
2. Assess Data Transmission: Analyze the results of the ping test and any other data transfer tests conducted.

Step 6: Document Findings

1. Record Observations: Document all measurements, observations, and any issues encountered during the experiment.
2. Conclude: Summarize the findings, discussing the effectiveness of PoE in powering devices and any limitations observed.

Safety Precautions

• Ensure all equipment is properly grounded.
• Avoid short-circuiting the Ethernet cables.
• Handle the multimeter with care to prevent electric shock.

Conclusion

This experiment will provide insights into how Power over Ethernet works, its efficiency, and its practical applications in networking environments. Adjust the experiment as needed based on available equipment and specific learning objectives.

Experiment - 79 :- Connecting an Integrated Wired Device to a Wireless Network

 AIM :-  Connecting an Integrated Wired Device to a Wireless Network

Materials Needed:

1. Integrated Wired Device (e.g., smart TV, gaming console, desktop computer)
2. Wireless Access Point (WAP)
3. Ethernet cable
4. Wireless router with an active internet connection
5. Computer or mobile device for configuration

Step 1: Set Up the Wireless Access Point (WAP)

Unbox the WAP: Take the Wireless Access Point out of the box and ensure you have all the necessary components (power adapter, Ethernet cable, etc.).

Power the WAP:

• Plug the WAP into a power outlet using the provided power adapter.

Step 2: Connect the WAP to the Wireless Router

Connect Using Ethernet:

• Use an Ethernet cable to connect the WAP to your wireless router.
• Plug one end of the Ethernet cable into the LAN port of the WAP and the other end into one of the LAN ports on your router.

Step 3: Configure the Wireless Access Point

Access the WAP Configuration Page:

• Connect your computer or mobile device to the WAP using another Ethernet cable (plug it into the WAP) or connect to the WAP’s default Wi-Fi network (check the WAP manual for the default SSID and password).
• Open a web browser and enter the WAP’s IP address in the address bar (commonly something like 192.168.0.1 or 192.168.1.1). Refer to the WAP manual for the exact address.

Log In:

• Enter the default username and password (often found in the manual or on the device itself). Common defaults are admin/admin or admin/password.

Configure Wireless Settings:

• Navigate to the wireless settings section.
• Set the WAP to connect to your existing wireless network (SSID).
• Enter the Wi-Fi password for your wireless network.
• Save the settings and allow the WAP to reboot if necessary.

Step 4: Connect the Integrated Wired Device

Connect the Wired Device:

• Use an Ethernet cable to connect your integrated wired device (e.g., smart TV, gaming console, or desktop computer) to one of the LAN ports on the WAP.

Step 5: Test the Connection

Power On the Wired Device: Turn on your integrated wired device if it’s not already on.

Check Network Connection:

• On the wired device, check the network settings to ensure it has obtained an IP address (this can usually be found in the network settings).
• You can also try to access the internet by opening a web browser and visiting a website.

Step 6: Troubleshooting (if necessary)

No Internet Access:

• Ensure the WAP is properly connected to the router and that the router is connected to the internet.
• Check the Ethernet cable connections.
• Verify that the WAP is configured correctly with the right SSID and password.

Wired Device Not Recognized:

• Ensure the Ethernet cable is functioning and securely connected.
• Restart the wired device and the WAP.

Conclusion

By following these steps, you have successfully connected an integrated wired device to a wireless network using a Wireless Access Point. This setup allows the wired device to access the internet wirelessly through the WAP, effectively bridging the gap between wired and wireless networks.
