Installing the Router

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

Step 1 Connect one end of the yellow Ethernet cable to built-in Ethernet switch port 4 on the router.

Step 2 Connect the other end of the cable to the RJ-45 port on the NIC installed in the PC, server, or workstation.

Note 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.

Connecting an External Ethernet Switch (Optional)

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. (Figure 2-2shows a Cisco 831 router, but it also applies to a SOHO 91 router. The connection procedure applies to both the Cisco 831 router and the SOHO 91 router.)
