Perform the following steps to connect the PC to port number 4 of the built-in 
switch:

Connect one end of the yellow Ethernet cable to built-in Ethernet switch port 4 on 
the router.

Connect the other end of the cable to the RJ-45 port on the NIC installed in the 
PC, server, or workstation.

Leave the PCs that you are connecting to the router turned off until after you 
complete the router installation.

You can connect additional servers, PCs, or workstations to built-in Ethernet 
switch ports 1, 2, and 3.

If more than four PCs need to be connected to each other in an office, you may 
connect an external Ethernet switch to the router’s built-in switch to add 
additional Ethernet connections to the router. To connect an external Ethernet 
switch to a built-in Ethernet switch port on the router, follow the steps given after 

Figure 2-2
