Question 557 - 220-1101 discussion

The output from the cable tester indicates that there is an open fault in the cable, which means that one or more of the wires in the cable are not connected properly or are broken. The open fault affects the wires 3, 4, and 6, which are used for transmitting and receiving data in Ethernet networks.The open fault can cause network connectivity issues, such as no link, slow speed, or packet loss12.

To resolve this issue, the technician should use a crimper and a punchdown tool, which are tools that are used to attach connectors to cables or wires to patch panels. A crimper is a tool that squeezes or crimps a connector, such as an RJ-45, to the end of a cable, ensuring that the wires are securely inserted into the pins of the connector. A punchdown tool is a tool that pushes or punches a wire into a slot on a patch panel, creating a connection between the wire and the panel.Both tools can be used to fix or replace the faulty wires or connectors that cause the open fault12.

The other options are not as effective or relevant as a crimper and a punchdown tool. A loopback plug is a tool that is used to test the functionality of a network port or device, by sending and receiving signals from the same port or device.A loopback plug can help diagnose network problems, such as faulty ports or devices, but it cannot fix the open fault in the cable12. A network tap is a tool that is used to monitor or capture network traffic, by creating a copy of the data that passes through a network link.A network tap can help analyze network performance, security, or troubleshooting, but it cannot fix the open fault in the cable12. A toner probe is a tool that is used to trace or identify a cable or wire, by sending and detecting an audible tone along the cable or wire.A toner probe can help locate or label network cables or wires, but it cannot fix the open fault in the cable12. A Wi-Fi analyzer is a tool that is used to scan or measure wireless networks, by displaying information such as signal strength, channel, encryption, etc.A Wi-Fi analyzer can help optimize or troubleshoot wireless networks, but it cannot fix the open fault in the cable12.
