16
To connect the PoE for the SIP-T40P IP phone:
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 this process.
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
Phone Status
You can view phone status via phone user interface or web user interface.
Available information of phone status includes:
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 18.
