CISCO NETWORKING ACADEMY PROGRAM (CNAP) SEMESTER 1/ MODULE 5 Cabling LANs and WANs 1 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Networking Fundamentals Objectives • Upon completion of this module, the student will be able to perform tasks related to the following: • Cabling the LAN • Cabling the WAN 2 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs LAN Physical Layer 3 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Ethernet in the Campus 4 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Ethernet Media & Connector 5 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Connection Media 6 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs UTP Implementation • Order of the wires in must follow EIA/TIA-T568-A or T568-B standards • Three types of patch cables: • Straight-though cable •Switch to router •Switch to PC or server •Hub to PC or server • Crossover cable •Switch to switch •Switch to hub •Hub to hub •Router to router •PC to PC •Router to PC • Rollover cable •console cable 7 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs UTP Implementation 8 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Repeaters 9 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Hubs • multiport repeaters (generally have from two to twenty-four ports) • data arriving over the cables to a hub port is electrically repeated on all the other ports connected to the same network segment, except for the port on which the data was sent 10 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Bridges 11 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Switches • Sometimes described multiport bridges • Operate at data link layer of OSI reference model • Switches use gathered information to build forwarding tables to determine the destination 12 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Switches 13 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Wireless • Wireless signals are electromagnetic waves that travel through the air • Wireless networks use Radio Frequency (RF), laser, infrared (IR), or satellite/microwaves to carry signals from one computer to another without a permanent cable connection • Two most common wireless technologies used for networking are: • IR - line of sight • RF - out of sight, two approaches used to implement spread spectrum for WLAN transmissions are Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) 14 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Host Connectivity • Host can connect to network using Network Interface Card (NIC) • NIC is layer-2 device and each NIC carries a unique code called MAC address 15 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Peer-to-peer & Client-server • Peer-to-peer • networked computers act as equal partners, or peers • users control their own resources • Client-server • server is a central computer that respond to requests from clients for file, print, application, and other services 16 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Peer-to-Peer VS Client/Server 17 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Peer-to-Peer VS Client/Server 18 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs WAN Physical Layer 19 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs WAN Serial Connection DTE: Data Terminal Equipment DCE: Data Communications Equipment CSU: Channel Service Unit DSU: Data Service Unit 20 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and Serial Connections 21 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and Serial Connections 22 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and Serial Connections 23 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and Serial Connections port type slot number / port number 24 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and ISDN BRI Connections • With ISDN BRI, two types of interfaces may be used, BRI S/T and BRI U • A BRI interface with an integrated NT1 is labeled BRI U • A BRI interface without an integrated NT1 is labeled BRI S/T 25 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and DSL Connections • To connect a router for DSL service, use a phone cable with RJ-11 connectors. • DSL works over standard telephone lines using pins 3 and 4 on a standard RJ-11 connector. 26 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Routers and Cable Connections • Coaxial cable and a BNC connector are used to connect the router and cable system 27 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Setting Up Console Connections 28 CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/ MODULE 5 Cabling LANs and WANs Summary 29
