other end of the power adapter into an electrical power outlet.
Note
Power over Ethernet
With the included or a regular Ethernet cable, the SIP-T27G IP phone can be powered from a
PoE-compliant switch or hub.
To connect the PoE:
1. Connect the Ethernet cable between the Internet port on the phone and an available port
on the in-line power switch/hub.
Note
If in-line power is provided, you don’t need to connect the phone to the power adapter. Make
sure the switch/hub is PoE-compliant.
Important! Do not remove power from the phone while it is updating firmware and
configurations.
The IP phone should be used with Yealink original power adapter (5V/1.2A) only. The use of the
third-party power adapter may cause the damage to the phone.
