Chapter 8 (2.8). Network Types and Networking Tools

Tone generator and probe

A technician is tasked with finding and labeling where a network connection terminates in a patch panel. Which of the following tools would be BEST for the technician to use A. Ethernet cable tester B. Tone generator and probe C. RJ-45 loopback plug D. Patch panel punchdown too

Tone generator and probe

These devices are used to locate cables in a wiring closet. The tone generator is typically placed at the user end, and a probe is waved around in the wiring closet to locate the connection. It will make a distinctive noise when it is near the correct cable.

patch tester

This device has two RJ45 jacks; you plug each end of the patch cable into the tester, and then press the button to make sure each wire makes a proper connection and has continuity.

loopback plug

This tool simulates a network connection and has two main functions. First, it can help find what port on a switch an RJ45 jack is wired to. Second, you can test the network adapter on a PC and find out if TCP/IP is functioning properly. This tool is essentially a really short crossover connection—the appropriate pins are crossed within the device, looping the signal and data back to where it came from.

RJ45 Crimper

Usually, you would buy patch cables for $2 or $3 each and be done with it. However, you can make them, too, using this tool. You would have to purchase cable as well as RJ45 plugs. The plugs are attached to the cable ends with an ________ _______ tool.

RJ45 crimper

What would be required to attach RJ45 plugs to the ends of a single patch cable?

Loopback plug

Which tool is used to test a network adapter not connected to the network?

Wi-Fi analyzer; 5 GHz

Your boss is concerned with overlapping wireless networks from neighboring companies using 802.11ac. Which tool should you use to analyze the problem, and which frequency should you display for analysis?

Wi-Fi Analyzer

a tool that can identify wireless networks on 2.4-GHz and 5-GHz frequencies. The tool shows things such as the channels used by neighboring wireless networks, any overlapping that might be occurring between those networks and yours, and the signal strength of access points. come in two types: handheld, all-in-one devices with a built-in Wi-Fi antenna and incorporated analysis programs (these are much more expensive); and then there are various apps for Windows, Android, and iOS.

cable cutter

first tool needed to install a physical wired network, used for cutting cable

cable tester

last tool needed to install a physical wired network - An electrical instrument that verifies if a signal is transmitted by a cable. Also called a media tester.

cable stripper

second tool needed to install a physical wired network - This tool is used to strip a portion of the plastic jacket off the cable, exposing the individual wires. At this point, you can separate the wires and get ready to terminate them

punchdown tool

third tool needed to install a physical wired network - This device punches the individual wires down into the 110 IDC clips of an RJ45 jack and the patch panel. This "punching down" of the wires is the actual termination.
