PoE Network Installation: Key Steps

Cable Installation - During this step, the installer must verify that all cables and connectors are properly connected. Typically, a cable tester is used to check for continuity. However, most basic cable testers only detect continuity issues, missing common faults. For example, a loose connection may still transmit signals but cause packet loss. Similarly, cables made from materials with poor conductivity, like aluminum, can have high internal resistance, affecting PoE power transmission. Our CT003 tester not only checks continuity but also measures resistance abnormalities in cables and connectors, helping to identify potential issues quickly. Once validated using our CT003, the cable installation is certified as complete and error-free.

PSE Installation - After installing the PSE, it's essential to check each remote port to ensure the PSE can deliver the required power. The CT003 tester helps by identifying the PoE mode and verifying the available voltage at each port, ensuring the system is functioning as expected.

PD Installation - Following the installation of the PD, the CT003 tester can monitor real-time power consumption. If the PD is drawing abnormally high or low power, this could indicate a problem with the device, warranting further investigation.

Comprehensive Testing Solution - Our CT003 PoE tester covers all aspects of PoE cabling and equipment installation. Additionally, the optional Port Mapping feature simplifies ongoing network maintenance, making it a valuable tool for both installation and long-term management.

POE Voltage Detection

Cable Test Results

• GREEN DOT – The corresponding wire pair has good continuity, and the wiring is correct.

• RED DOT – The corresponding wire pair has a short or is miswired. •

• RED X – The corresponding wire pair has an open circuit.

• ORANGE DOT – The corresponding wire pair has Resistance that is too high, NOT safe for POE

  • Resistance measurement is an indicator of material and connection quality; and also indicates power transmission capability for POE application

  • Possible reasons for high resistance:

    • Cable is too long

    • mproper contact or termination of the RJ45 connector

    • Improper cable conductor (CCA or the conductor is too thin)

    • Improper cable construction

Case Study 1 - the Faulty Network

In the bustling heart of Taipei's Xinyi District, a newly constructed office building was grappling with a persistent network issue. Despite meticulous installation of the Power over Ethernet (PoE) system, devices were frequently disconnecting and data transmission was erratic.

Network technician Ethan was tasked with diagnosing the problem. Armed with his trusty CT003 POE tester, Ethan began a methodical investigation.

First, he examined the cable installation. With the CT003, he meticulously tested each cable segment for continuity and resistance. To his surprise, he discovered a loose connection between two cables in the server room. While the connection seemed secure to the naked eye, the CT003 revealed a subtle increase in resistance, indicating a potential fault.

Ethan tightened the connection and retested. The resistance reading returned to normal. This seemingly minor issue had been the root cause of the network instability, leading to frequent device disconnections and data loss.

Next, Ethan turned his attention to the Power Source Equipment (PSE). Using the CT003, he verified that each port was supplying the correct PoE mode and voltage. He found that one port was delivering insufficient power, potentially causing devices to malfunction.

After adjusting the PSE settings, Ethan checked the Power Devices (PDs) connected to the network. With the CT003's real-time power consumption monitoring, he identified a PD that was drawing significantly more power than expected. Further investigation revealed a faulty component within the PD itself.

By systematically addressing these issues with the help of the CT003, Ethan was able to restore the network's stability and ensure the smooth operation of the office building's devices. The CT003 proved to be an invaluable tool in diagnosing and resolving network problems, demonstrating its effectiveness in complex POE installations.

Case Study 2 - POE Hero Alex

In a quiet, sunlit office building, a team of IT specialists was preparing for a critical installation: a new Power over Ethernet (PoE) network that would power everything from surveillance cameras to wireless access points. The lead technician, Alex, knew that success depended on following three essential steps: cable installation, PSE setup, and PD installation.

Step 1: The Cable Installation - The team began by pulling cables through the building’s ceiling. Alex's focus was sharp as he oversaw the work. He knew from experience that a seemingly solid cable connection could hide subtle issues. "Make sure every connector is properly seated," he reminded his team. But to be sure, Alex pulled out their secret weapon—the CT003 tester.

Unlike most testers that only check for continuity, the CT003 went further. As Alex connected the cables to the device, it measured resistance across each wire. This test was critical. If any part of the cable had excessive resistance due to poor quality materials, like aluminum, it could still transmit signals but would struggle to deliver the power required for PoE devices. "Everything's clear," Alex said with a smile after validating all the cables. The cable installation was complete and certified to be problem-free.

Step 2: The PSE Installation - With the cables in place, the team moved on to installing the Power Sourcing Equipment (PSE). This was the heart of the network, responsible for supplying power to all connected devices. Alex knew they couldn't just assume the PSE was working properly, so he used the CT003 tester again. This time, the tester checked each remote port to confirm that the correct PoE mode was enabled and that the voltage was sufficient to power the devices. "Perfect. The PSE is supplying power as expected," Alex noted, feeling a sense of progress.

Step 3: The PD Installation - Finally, it was time to install the Powered Devices (PDs), like cameras and access points. Once again, the CT003 played a crucial role. As each device was connected, the tester displayed real-time power consumption. One of the cameras was drawing unusually high power. "This one's off. Let’s check it out," Alex said, immediately identifying the faulty device that needed attention. Thanks to the CT003, they could troubleshoot the issue before it became a problem.

With all systems in place, Alex took a moment to reflect. The CT003 PoE tester had been the unsung hero of the day, ensuring every part of the installation went smoothly. Its Port Mapping feature would also make future maintenance effortless, helping the team keep the network running smoothly long after they had completed the installation.

As they packed up their gear, Alex smiled at the thought of the flawless network they had just built, all thanks to careful planning and the power of the right tools.
