YEALINK NETWORK TECHNOLOGY CO. LTD. T54S 用户手册

You have two options for network and power connections. Your system administrator will advise you which 

one to use.

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 interface.

Note: 

The IP phone should be used with Yealink original power adapter (5V/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.

Note:

 

The USB port can also be used to connect the Wi-Fi USB dongle WF40, color-screen expansion module 

          EXP50 and USB headset. 

          The Wi-Fi USB dongle WF40 and color-screen expansion module EXP50 should be purchased separately.

          For more information on how to use the WF40 and EXP50, refer to Yealink Wi-Fi USB Dongle WF40 User 

          Guide and Yealink EXP50 User Guide. For more information on how to use USB headset, refer to the 

          documentation from the manufacturer.
