Basics to Netoworking Class

Updated on November 10, 2014

Configure TCP/IP


Note: When choosing the default gateway value, choose the IP address of the router that is on the same subnet as the host.

Complete the following steps:

  1. Click the Office2 monitor icon shown in Office 2 to go to the operating system.
  2. In the Task Bar, click the network icon and select Open Network and Sharing Center.
  3. Click the Local Area Connection link.
  4. Click the Properties button.
  5. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
  6. To manually configure the IP address and default gateway, select Use the following IP address:. Type the required configuration values identified in the table above. Click OK.
  7. Click Close.
  8. Click Close.

To confirm that the workstation is connected to the network and the Internet, click on the network icon in the Task Bar and select Open Network and Sharing Center. The diagram should indicate an active connection to the network and the Internet.

Connect to an Ethernet Port

To complete this lab, use twisted pair cable with RJ-45 connectors to connect to a wired Ethernet network. RJ-45 connectors have 8 wires (as seen below), and are larger than RJ-11 connectors.

Complete the following steps:

  1. Click the Hardware icon shown in Office 1 to go to the workstation.
  2. In Office 1, switch to the back view of the computer.
  3. On the Shelf, expand the Cables category.
  4. Select each cable type. Examine the cable ends in the Selected Component window to identify the cable with RJ-45 connectors.
  5. In the Selected Component window, select a cable end. Drag and drop the connector to the Ethernet port on the computer.
  6. In the Selected Component window, drag the other connector to the Ethernet port on the wall outlet.
  7. To confirm that the workstation has a connection to the local network and the Internet, click the Windows icon on the monitor.
  8. Click on the network icon in the Task Bar and select Open Network and Sharing Center. The diagram should indicate an active connection to the network and the Internet.

Connect a Cable Modem

2.2.3 Connect a Cable Modem

To complete this lab:

  • Add the cable modem to the Bench. Connect the modem to the WAN connection using the RG-6 coaxial cable. Both RG-6 and RG-59 are 75 ohms and can be used, but RG-6 has less signal loss than RG-59. RG-58 cables are used for 10Base2 Ethernet and have a BNC connector.
  • Connect the computer to the cable modem using a Cat5e Ethernet cable.
  • Use the AC to DC power adapter to plug in the modem.

Complete the following steps:

  1. On the Shelf, expand the Modems category.
  2. Drag the cable modem from the Shelf to the Bench.
  3. To connect the modem to the Internet connection, switch to the back view of the cable modem.
  4. On the Shelf, expand the Cables category.
  5. Select the RG-6 coaxial cable.
  6. In the Selected Component window, drag a connector to the port on the cable modem.
  7. In the Selected Component window, drag the other connector to the port on the wall plate.
  8. To connect the computer to the cable modem, switch to the back view of the computer.
  9. On the Shelf, select the Cat5e Ethernet cable.
  10. In the Selected Component window, drag a connector to the Ethernet port on the cable modem.
  11. In the Selected Component window, drag the other connector to the Ethernet port on the computer.
  12. To plug in the cable modem, select the power adapter on the Shelf.
  13. In the Selected Component window, drag the DC power connector to the port on the cable modem.
  14. In the Selected Component window, drag the AC adapter end to the power outlet.
  15. Click the Windows icon on the monitor.
  16. Click the networking icon in the Task Bar and select Open Network and Sharing Center. The diagram should indicate an active connection to the home network and the Internet.

Connect a Fiber Optic Cable

Use the ST to LC cable to connect the server to the switch using a fiber optic connection.

  • ST cables have two connectors that twist on using BNC connectors: one for transmit (Tx) and one for receive (Rx).
  • An LC connector has both connectors linked together such that the connector can only be inserted one way.

When connecting the cable to the server:

  • Connect the transmit port on the switch to the receive port on the server; connect the receive port on the switch to the transmit port on the server.
  • The switch transmits from the port on the left. When the cable is connected, the connector with the white sleeve is on the left `(this is the B connector in the LC connector).
  • The other end of this cable is the ST connector with the black sleeve. Connect this connector to the Rx port on the server.
  • The switch receives from the port on the right. When the cable is connected, the connector with the yellow sleeve is on the right (this is the A connector in the LC connector). Connect the red/orange connector on the other end to the Tx port on the server.

Complete the following steps:

  1. In the Networking Closet, examine the ports on the switch to identify the fiber optic port types.
  2. Switch to the back view of the rack, and examine the ports on the new server (i.e., bottom server).
  3. On the Shelf, expand the Cables category.
  4. Select each cable on the Shelf. In the Selected Component window, examine the connector ends of each cable to identify the cable with the required connectors. Select the ST to LC cable.
  5. In the Selected Component window, drag the ST B connector (black) to the Rx port on the server.
  6. In the Selected Component window, drag the ST A connector (red or orange) to the Tx port on the server.
  7. Switch to the front view of the rack.
  8. To connect the server and the switch, drag the LC connector to one of the fiber optic ports on the switch (the ports on the far right).
