Power over Ethernet
With the included or a regular Ethernet cable, the SIP-T27P 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
Phone Initialization
After your phone is powered on, the system boots up and performs the following steps:
Automatic Phone Initialization
The phone finishes the initialization by loading the saved configuration. The LCD screen displays
"Welcome Initializing…please wait" during the initialization.
DHCP (Dynamic Host Configuration Protocol)
The phone attempts to contact a DHCP server in your network to obtain valid IPv4 network
settings (e.g., IP address, subnet mask, default gateway address and DNS address) by default.
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.
The phone can also share the network with another network device such as a PC (personal
computer). This is an optional connection. We recommend that you use the Ethernet cable
provided by Yealink. The PC port may be disabled, contact your system administrator for more
information.
Important! Do not remove power from the phone while it is updating firmware and
configurations.
If your network does not use DHCP, proceed to Basic Network Settings on page 20.
