Connecting a Phone
To connect an 802.3af-compliant phone to an Ethernet switch port, follow these steps:
Note A power source must be provided for the phone to function. This can be done in two ways: the phone
can be powered via the PoE function using the PoE enabled Ethernet ports, or by using an external AC
power source connected to the phone.
Step 1 Connect one end of the yellow Ethernet cable to Ethernet switch port 0 or port 1 on the router. Figure 3-2
shows a Cisco 888W router connected to a phone.
