4. Connect the network and power, as shown below:
You have two options for network and power connections. Your system administrator will advise you which
one to use.
Note:
• The IP phone should be used with Yealink original power adapter (5V/1.2A) only. The use of the
third-party power adapter may cause the damage to the phone. If you are connecting a PC to your
phone, we recommend that you use the Ethernet cable provided by Yealink.
• If inline power (PoE) is provided, you don’t need to connect the power adapter. Make sure the
hub/switch is PoE-compliant.
