Getting Started
13
To connect the PoE for the SIP-T19P 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
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 “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 and
IPv6 network settings (e.g., IP address, subnet mask, default gateway address and DNS
address) by default.
Note
You can view phone status via phone user interface or web user interface.
Available information of phone status includes:

Network status (e.g., IPv4 status, IPv6 status, IP mode and MAC address).

Phone status (e.g., device model, hardware version, firmware version, product ID,
MAC address and device certificate status).
If in-line power switch/hub 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). It is an optional connection.
Important! Do not unplug or remove power to the phone while it is updating firmware
and configurations.
If your network does not use DHCP, proceed to Basic Network Settings on page 15 .
