Select the Cat5e cable with RJ-45 connectors. 12. In the Selected Component window, drag a connector to the Ethernet port on the back of Home-PC. 13. In the Selected Component window, drag a connector to an Ethernet port on the hub. 14. To confirm that Home-PC is properly connected to the network and Internet, click the Windows icon on the monitor on the left. 15. In the notification area, click the networking icon and click Open Network and Sharing Center. The diagram should indicate an active connection to the home network and the Internet. 16. To connect Home-PC2 (the computer on the right) to the hub, switch to the Workspace. 17. Repeat steps 11 through 13 to make the connection, and then repeat steps 14 and 15 to confirm the connection.
You are working on a small office/home office (SOHO) network. After adding a hub to the network so Home-PC and Home-PC2 could communicate and have successful connection to the Internet, the customer has noticed a connection delay whenever the computers use the network at the same time. You believe the delay might be related to the shared bandwidth on the network.
-Place the managed switch on the Bench -Connect the cable modem to the managed switch -Use Cat5e cables to connect both computers to the managed switch -Provide power to the managed switch -Confirm that the two computers are properly connected to the local network and the Internet Explanation To meet the requirements, you will need to select a managed switch. The following are the essential differences between the networking devices offered in this scenario: A switch creates a connection for computers in a local area network, and offers guaranteed bandwidth between the devices. Types of switches include: Managed switches allow administrators to change the port configurations, including the following: Port speed Filters based on network adapter MAC addresses Unmanaged switches are autonomous in their function, requiring no port management or configuration. A router connects devices on two different networks, but many routers (such as the ones shown here) also include integrated Ethernet ports for the LAN. Selecting a router with an integrated hub or switch is not necessary for this scenario. Complete the following steps: 1. On the Shelf, expand the Networking Devices category. 2. Read the device descriptions to identify the switch. Drag the Managed Switch to the Workspace (preferably next to the existing hub). 3. Switch to the back view of the managed switch and the hub. 4. To plug in the switch, select the DC power connector on the hub and drag it to the power port on the switch. 5. To connect the Home-PC, Home-PC2, and the cable modem to the switch, select an Ethernet cable on the hub, and drag it to an open Ethernet port on the switch. Repeat for each Ethernet connection on the hub. 6. To confirm that Home-PC is properly connected to the network and Internet, click the Windows icon on the monitor on the left. 7. In the notification area, click the networking icon and click Open Network and Sharing Center. The diagram should indicate an active connection to the home network and the Internet. 8. To confirm the connection for Home-PC2, switch back to the bench and click the Windows icon on the monitor on the right. 9. Repeat step 7.
