AC Power 
To connect the AC power: 
1.  Connect the DC plug on the power adapter to the DC5V port on the phone and 
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. 
 
Note 
Power over Ethernet 
With the included or a regular Ethernet cable, the SIP-T23P/G IP phone can be powered 
from a PoE-compliant switch or hub. 
   
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.
