Thediagram below shows an example of how to place the wires on one type of jack. Most jacks will havethe channels color-coded to indicate where the wires go. The photo of the jack on the next pageshows one variety of jack. Jacks are typically stamped to indicate whether they are T568A or B asshown in the photo.1-2CCNA 1: Networking Basics v 3.1 - Lab 5.1.5Copyright 2003, Cisco Systems, Inc.Step 3Use the 110 punch-down tool shown below to push conductors into the channels.
Make sure toposition the cut side of the punch-down tool so that it faces the outside of the jack. If this is not done,it will cut the wire being punched down. Try tilting the handle of the punch tool a little to the outside,so it will cut better. If any wire remains attached after using the punch tool, simply twist the endsgently to remove them. Then place the clips on the jack, and tighten them. Make sure that no morethan 1.27 cm (one half inch) of untwisted wire is between the end of the cable jacket and thechannels on the jack.Step 4Snap the jack into its faceplate by pushing it in from the back side.
Make sure when this is done, thatthe jack is right-side up so the clip faces down when the wall plate is mounted.Step 5Use the screws to attach the faceplate to either the box or to the bracket. If there is a surfacemounted box, keep in mind that it might hold 30 - 60 cm (1 - 2 feet) of excess cable. Then it will benecessary to either slide the cable through its tie-wraps or pull back the raceway that covers it inorder to push the rest of the excess cable back into the wall.
If there is a flush-mounted jack, all thatis needed is to push the excess cable back into the wall.Category 5 T568B Jack Wiring Color SchemeHold the jack with the 8-pin jack receptacle, which is the part that the RJ-45 connector goes into,facing up or away from the body while looking at the wire channels or slots. There should be fourwire channels on each side.
Match the wiring colors to the codes on the jack.8-pin receptacle2-2White GreenWhite BlueGreenBlueWhite BrownWhite OrangeBrownOrangeCCNA 1: Networking Basics v 3.1 - Lab 5.1.5Copyright 2003, Cisco Systems, Inc.Lab 5.1.7 Hub and NIC PurchaseObjective•Introduce the variety and prices of network components in the market•Gather pricing information for hubs and Ethernet NICs for a small networkBackground / PreparationA friend has asked for help putting together a price list for a small LAN to be set up in a very smallbusiness.
Rapid growth is not really a concern. The business has computers, but it has notnetworked the computers together. They are getting a DSL connection, so that they can access theInternet. They have been told that all they need is a small hub and connections to each computer tocomplete the project. Each machine is running a version of Windows that will work on a peer-to-peernetwork. The lab will use the Web site www.cdw.com, but any local source, catalog, or Web site canbe used. The requirements include the following:1 – Ethernet Hub2 – Ethernet NICs for existing laptop PCs3 – Ethernet NICs for existing desktop PCs4 – Ethernet Cat 5e jumper cables – length 6.1 meters (20 feet)Step 1 Research equipment pricingUse at least three other sources for technologies and pricing.
For Web searches, try www.cdw.com,www.google.com, or any other search engines that are preferred. Look at the prices for small hubsand how much more would it cost to use a small switch. Compare the cost to a wirelessimplementation.Step 2 Compile one page summary of the resultsUse Microsoft Excel, Word, or any comparable products to compile a one page summary of theresults. A comparison table should show the choices and the features or factors that were compared,such as number of ports, features, price, performance, and so on.1-1CCNA 1: Networking Basics v 3.1 - Lab 5.1.7Copyright 2003, Cisco Systems, Inc.Lab 5.1.10 Purchasing LAN SwitchesObjective•Introduce the variety and prices of network components in the market•Gather pricing information for Ethernet switches and NICs for a networkBackground / PreparationPut together a proposal for replacing hubs with switches at a branch office.
Research at least twodifferent solutions and develop a proposal. The project details are the following:1-2•The company has a branch location still using an Ethernet hub network. Congestion issues aregetting to be a serious problem as more and more services are being added to the network.Currently each of the four floors has one or more hubs in a wiring closet supporting 30-35computers except the ground floor, which has 65 computers.•The four floors plug into an 8-port 10-Mbps switch that was added earlier to reduce thecongestion problems. While that solution was a major improvement it cannot keep up all of thetime anymore. The two servers and router to the Internet also connect to the 8-port switch.•The branch cabling is relatively new and certified to Category 5 standards.
The company is notinterested in any major cabling changes at this time.•At least 75% of the 160 current workstations have NICs with 10/100, full duplex capabilities. Alllaptop computers have the newer NICs. All new machines include similar NICs.•Consider what should be done with the existing switch.
Are there higher bandwidth options forconnecting the two servers?CCNA 1: Networking Basics v 3.1 - Lab 5.1.10Copyright 2003, Cisco Systems, Inc.The requirements include the following:•Replace all hubs with switches.•Replace the 10 Mbps NICs for existing desktop PCs.•Each host connection should be 10/100 Mbps minimum.Step 1 Research equipment pricingStart by going to www.cisco.com and selecting “Products & Solutions” and following the links to“Switches” to gather basic information.
Look specifically at the Catalyst 29xx and 35xx models.Use at least three other sources for technologies and pricing. When doing Web searches, trywww.cdw.com, www.google.com, or any other preferred search engines.Step 2 Compile a table of your resultsUse Microsoft Excel, Word, or any comparable products to compile a table of the results.The first page is The Executive Summary where the recommended choice of products and the totalcost is written.
Include a short 8-15 line reason why this implementation was selected.The second page is a comparison table showing the choices that were looked at and the features orfactors that were compared such as price, performance, and so on.The third page explains any security concerns discovered in the research. Summarize them as abulleted list. Summarize whether the concerns are serious and if they can be overcome.Optional Step 2 Create a 4-8 slide PowerPoint presentationInstead of creating the above Excel or Word documents, create a four to eight slide PowerPointpresentation covering the same requirements.Assume that there will be a presentation of the material.If time allows, do both of these. That would often be the norm.2-2CCNA 1: Networking Basics v 3.1 - Lab 5.1.10Copyright 2003, Cisco Systems, Inc.Lab 5.1.12 Building a Peer-to-Peer NetworkObjective•Create a simple peer-to-peer network between two PCs•Identify the proper cable to connect the two PCs•Configure workstation IP address information•Test connectivity using the ping command.Background / PreparationThis lab focuses on the ability to connect two PCs to create a simple peer-to-peer Ethernet LANbetween two workstations.
The workstations will be directly connected to each other without using ahub or switch. In addition to the Layer 1 physical and Layer 2 data link connections, the computersmust also be configured with the correct IP network settings, which is Layer 3, so that they cancommunicate. A basic Category 5/5e UTP crossover cable is all that is needed.
A crossover cable isthe same type that would be used as backbone or vertical cabling to connect switches together.Connecting the PCs in this manner can be very useful for transferring files at high speed and fortroubleshooting interconnecting devices between PCs. If the two PCs can be connected with a singlecable and are able to communicate, then any networking problems are not with the PCs themselves.Start this lab with the equipment turned off and with cabling disconnected. Work in teams of two withone person per PC. The following resources will be required:•Two workstations with an Ethernet 10/100 NIC installed•Several Ethernet cables, which are both straight-through and crossover, to choose from forconnecting the two workstationsStep 1 Identify the proper Ethernet cable and connect the two PCsa.
