To connect the AC power:

connect the other end of the power adapter into an electrical power outlet.
2. Connect the included or a standard Ethernet cable between the Internet port on
the phone and the one on the wall or switch/hub device port.

Power over Ethernet
With the included or a regular Ethernet cable, the SIP-T21P E2 IP phone can be powered
from a PoE-compliant switch or hub.
PoE is not applicable to the SIP-T21 E2 IP phone.
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.
