Note: The IP phone should be used with Yealink original power adapter (5V/600mA) 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 do not need to connect the power adapter. Make sure the hub/switch
is PoE-compliant. PoE is only applicable to the SIP-T21P E2 IP phone.
After the IP phone is connected to the network and
supplied with power, it automatically begins the
initialization process. After startup, the phone is ready
for use. You can configure the phone via phone user
interface or web user interfafce.
