Connecting an External Ethernet Switch
If more than four PCs in an office must be connected to each other, you can add Ethernet connections to
the router by connecting an external Ethernet switch to the Ethernet switch on the router.
To connect an external Ethernet switch to an Ethernet switch port on the router, perform these steps:
Step 1 Connect one end of the yellow Ethernet cable to an Ethernet switch port on the router. Figure 3-2 shows
a Cisco 888W router connected to an Ethernet switch.

connections.
