Connecting two Expansion Modules
Note:
The T43U/T46U/T48U
IP phone can support 3 expansion modules at most. But if you use the
expansion module on the T43U or use more than one expansion module on the T46U/T48U, you
need to connect an additional Yealink power adapter (5V/2A) to any one of the expansion
modules. The power adapter should be purchased separately.
Connecting the USB Cable
Note:
You just need to connect the USB jack of the previous module and the mini USB jack of the
next module using a USB cable.
