1. PC Support & Repair Chapter 15 Advanced Networks

2. Objectives After completing this chapter, you will meet these objectives: Identify potential safety hazards and implement proper safety procedures related to networks. Design a network based on the customer's needs. Determine the components for your customer's network. Implement the customer's network. Upgrade the customer's network. Describe installation, configuration, and management of a simple mail server. Describe preventive maintenance procedures for networks. Troubleshoot the network.

3. Safety Hazards & Procedures Installing cabling can be dangerous! Proper clothing & shoes Ladder safety Tool safety Cable safety

4. Fiber Optic Cable Safety Require training to cut/splice/repair fiber cables Chemical safety Solvents & glues used are dangerous Tool safety Sharp, compression, cuts glass & plastic Watch for flying shards Hard to see; can cut you Light safety Cant see light, can damage eyes Careful with magnifier (for inspecting)

5. Copper Cable Safety Copper strands are sharp Can cut you Can fly into air & eye Tools are sharp

7. Design a network based on needs Determine a topology. Determine protocols and network applications.

8. Determine the Topology Site Survey Estimate # of users & future growth Location of computers Location of network equipment & servers Cable/wireless Get blueprint or draw it yourself Note space, power, security, air conditioning Can you name the topologies?

9. Determine Protocols TCP/IP required for Internet NetBEUI No connection to Internet Fast, but only good for small networks IPX/SPX Used for old Novell networks (use TCP/IP now) AppleTalk Old, uses TCP/IP now

10. TCP/IP Protocols

11. More TCP/IP Protocols

12. Review

14. Determine Components for Network Select cable types. Select an ISP connection type. Select network cards. Select the network device.

15. Select Cable Types UTP Cat5 & Cat5e 5e can handle higher speeds Up to 330ft Cat6 & Cat6A Splits pairs in upper/lower 6A-For faster speeds; up to 10Gbps 10GBase-T Cables connect to central MDF Use Plenum rated for in walls & dropped ceilings Retards fires

16. More Cable Types Wireless Use where cables cant be installed Older, historic buildings Cost Wiring is a one-time, expensive cost Little maintenance after installed Security Wired is more secure than wireless

17. Select an ISP Connection Consider: Speed Reliability Availability

18. ISP Connections

19. Scenarios Choose which type of ISP service youd use.

20. Selecting a Network Card Desktop- integrated or expansion slot Laptop- integrated or PC Card USB adapters Ethernet Card or Gigabit Ethernet Card Should match speed of switch port Which for a Linksys E3000?

21. Wireless Network Cards 802.11a B G N

22. Select Your Network Device Hub Slow Basic sharing of data Data goes to all Switch Faster than hub Smart Data goes to the one Router One port connects to Internet Called a gateway device Also can be multi-function

26. Implement the Network Install and test the customer's network. Configure the customer's Internet and network resources.

27. Perform the Install Plan first! Install cables in wall One feeds another pulls Terminate cables & test Check net cards & configure for TCP/IP Install switches/routers in secure location Put patch cable from jack to PC Test Ipconfig /all & ping

28. Configure the Internet Connection Temporary Internet files Help pages display faster Delete every so often Default Browser File Sharing Right-click on folder, Sharing Read, Change, Full Control Print Sharing Right-click, Sharing

29. Lab 3 computers connected by a hub, sharing a printer and a folder. 192.168.1.1, 1.2, 1.3 Printer connected locally to 1.2 computer Folder GCIT in Documents on computer 1.1

31. Upgrade the Network Install and configure a wireless NIC. Install and configure a wireless router. Test a connection.

32. Install a Wireless NIC Wireless PCI or USB Check version Install drivers Set IP Static or DHCP Packet Tracer Lab 15.5.1

33. Install & Configure Wireless Router Find a good location Central to all is best Connect to modem & a computer Log in through browser Whats the IP usually? Select mode (mixed, B, G, N) Static/DHCP SSID & broadcast Security Firmware Update

34. Test the Wireless Connection Connection status (Enabled/Disabled) Double-click for status In Vista, Network and Sharing Center > Manage Network Connections. Double-click the Wireless Network Connection to display the status.

35. Testing the Connection Ipconfig /all, /release, /renew Ping Tests connectivity Ping 192.168.1.7 –n 789 Ping 192.168.1.7 –t Nslookup Tests DNS Nslookup www.cisco.comwww.cisco.com Nslookup 64.190.7.89 Packet Tracer Lab 15.5.3
