1.Now that you have read the chapter about the OSI model, how would you change it? Are there inefficiencies or redundancies in the model?2.Use the following worksheet to complete the Ethernet Lab. At

Learning Objectives

In this lab, you will research a TIA/EIA 568B patch cable. When you have completed this lab you will be able to

• Identify proper orientation of RJ-45 connectors

• Identify the wire pairs of a UTP patch cable according to the specifications of the TIA/EIA 568B standard

Lab Materials and Setup

• The Mike Meyers' CompTIA Network+ Guide to Managing and Troubleshooting Networks textbook

• A computer with Internet access

• Pencil and paper

Instructions – Part 1

The TIA/EIA 568B standard defines the arrangement of 4 pair UTP cabling into RJ 45 connector. In purchasing commercial premade cables the emerging standard is 568B.

Task 1: Using the Internet conduct a search for the TIA/EIA 568B standard wiring diagram. There are many sites that offer color coded diagrams for wiring straight through patch cables.

Using your color coded diagram record the proper color wire for each of the pins of the RJ 45 modular connector when assembled using the TIA/EIA 568B standard.

Optional:

When possible in class we would make cables using these standards. Depending on this course format, that may not be possible. However if you have an extra UTP cable available you can examine or disassemble it to compare the concepts and layout of the pairs.

In this lab, you'll examine the standards and technology of 1000BaseT, 1000BaseSX, and 1000BaseLX Ethernet. When you have completed this lab, you will be able to

• Define the 1000BaseT Ethernet specifications, requirements, and limitations

• Define the 1000BaseSX and 1000BaseLX Ethernet specifications, requirements, and limitations

• Recommend Gigabit Ethernet NICs

• Determine appropriate use of fiber-optic Ethernet based on application

Your client is building a new regional complex consisting of two physical buildings. One building will house all of the administrative departments. The other building, located approximately 900 feet away from the administrative building, will be a large, garage-like structure where the inspection of automobiles will be conducted. The professional installers have submitted a proposal that has been accepted, outlining the following parameters:

• The proposed cabling for the internal office space of the administrative building is Category 6 UTP. The administrative network will need to support 75 to 100 devices (servers, computers, and printers).

• The proposed cabling for the internal area of the inspection building is Category 6 UTP. The network in the inspection building will need to support 25 to 40 devices (computers and printers).

• For the backbone between the two buildings, the proposal is single-mode 12-fiber optic cabling.

Using this general information, follow Steps 1 through 4 to develop an implementation plan for the new site. The design should take advantage of the Gigabit Ethernet technology.

Task 1: Utilizing the textbook and online resources, research and document the following information for 1000BaseT Ethernet:

Task 2: Utilizing online resources research and document the following information for 1000BaseTX Ethernet:

Task 3: Utilizing the textbook and online resources, research and document the following information for 1000BaseSX Ethernet:

Task 4: Utilizing the textbook and online resources, research and document the following information for 1000BaseLX Ethernet

Task 5: Utilizing online resources research and document the following information for 1000BaseZX Ethernet:

Task 6: As discussed in the scenario, the new facility will have approximately 100 to 140 network devices (computers and printers). In order to implement Gigabit Ethernet throughout the organization, each device will need a gigabit NIC. Launch your browser and research the current pricing for Gigabit Ethernet NICs. Document your findings in the following space:
