Connecting two Expansion Modules
Note: The T52S/T54S/T56A/T58A/T58V IP phone can support 3 expansion modules at most. But if you
use more than one expansion module, 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.
The slots are plugged up by silica gel. You can pull out the silica gel when cascading
expansion modules.
