8.6 Planning Structured Cabling: Electricity and Grounding 8.6.1 Differences between AC and DC Instructor Note Jumping back to electrical topics may seem to be redundant. . But in our discussions of where to put wiring closets, where to run cable, which backbone cabling to use, and others,

8.5 Planning Structured Cabling: Horizontal and Backbone Cabling 8.5.1 Catchment area problems Instructor Note The purpose of this target indicator is to introduce what happens in larger buildings. Unlike the prior example for choosing a wiring closet, many buildings will require cable runs greater

8.4 Planning Structured Cabling: Selection Practice 8.4.1 Building description Instructor Note The purpose of this target indicator is to give the student more practice in determining the location of wiring closets. Note that the overall dimensions of the building are rather small. This is

8.3 Planning Structured Cabling: Identifying Potential Wiring Closets 8.3.1 Topology as floor plan Instructor Note The first step in locating a wiring closet is to obtain, or create, to-scale floor-plans of the area the network will service. You may use the diagram given in the curriculum. However,

8.2 Planning Structured Cabling: Wiring Closet Specifications 8.2.1 Overview of wiring closet selection One of the early decisions you must make when planning your network is where to place the wiring closet(s), since this will be where you will have to install many of the networking cables and

Overview Now that you a firm understanding of data flow through the OSI model, along with Layer 1 and 2 concepts and technologies, you are ready to start learning how to design networks. Network design takes many technologies into consideration (e.g. token-ring, FDDI, and Ethernet). For example, a

Lab 7.6.2 Network DiscoveryEstimated time: 20 min.Objectives:Use Network Inspector (or equivalent) Software to Perform Network Discovery. Background:One of the most powerful tools for troubleshooting computer networks is Network Management software. There are many fine programs for performing

7.6 Basic Ethernet 10Base-T Troubleshooting 7.6.1 Troubleshooting workstations Instructor Note The purpose of this target indicator is to present the students an approach to problem-solving based on the OSI model. Often lower layer problems (layer 1, layer 2) underlie our inability to use layer 7

7.5 Effects of Layer 2 Devices on Data Flow 7.5.1 Ethernet LAN segmentation Instructor Note A crucial concept in understanding how real networks are designed is segmentation. Segmentation is also an important concept on the CCNA exam. This introduction to segmentation presents three devices for

7.3 Ethernet and IEEE 802.3 7.3.1 Comparing Ethernet and IEEE 802.3 Instructor Note The purpose of this target indicator is to introduce both Ethernet and the IEEE 802.3 standard. The Ethernet family is the most popular LAN technology in use today and students should develop a solid understanding
