About This Guide

	Thank you for choosing the SIP-T21 E2/SIP-T21P E2 (hereinafter referred to as SIP-T21(P) E2)
	IP phone, exquisitely designed to provide business telephony features, such as Call
	Hold, Call Transfer, Busy Lamp Field, Multicast Paging and Conference over an IP
	network. The difference between the SIP-T21 E2 and SIP-T21P E2 IP phones is that only
	SIP-T21P E2 supports PoE.
	This guide provides everything you need to quickly use your new phone. First, verify
	with your system administrator that the IP network is ready for phone configuration. Also
	be sure to read the Packaging Contents and Regulatory Notices sections in this guide
	before you set up and use the SIP-T21(P) E2 IP phone.
Note
	Network Directory and Network Call Log features are hidden for IP phones in neutral
	firmware, which are designed for the BroadWorks environment. Please contact your
	system administrator for more information.

Two ways to customize configurations of your SIP-T21(P) E2 IP phone:

The user interface on the IP phone.

The user interface in a web browser on your PC.

The hardware components keypad and LCD screen constitute the phone user interface, which allows the user to execute all call operation tasks and basic configuration changes directly on the phone. In addition, you can use the web user interface to access all configuration settings. In many cases, either the phone user interface and/or the web user interface interchangeably. However, in some cases, it is only possible to use one or the other interface to operate the phone and change settings.

You can customize your phone by pressing the Menu soft key to access the phone user

interface. The Advanced Settings option is only accessible to the administrator, and the default administrator password is “admin” (case-sensitive). For more information on customizing your phone with the available options from the phone user interface, refer to Customizing Your Phone on page 25.

In addition to the phone user interface, you can also customize your phone via web user interface. In order to access the web user interface, you need to know the IP address of your new phone. To obtain the IP address, press the OK key on the phone. Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10) in the address bar of web browser on your PC. The default administrator user name and password are both “admin” (case-sensitive).

14

Getting Started

3)Connect the network and power

You have two options for power and network connections. Your system administrator will advise you which one to use.

AC power

Power over Ethernet (PoE)

Note PoE is not applicable to the SIP-T21 E2 IP phone.

AC Power

To connect the AC power:

1.Connect the DC plug on the power adapter to the DC5V port on the phone and connect the other end of the power adapter into an electrical power outlet.

2.Connect the included or a standard Ethernet cable between the Internet port on the phone and the one on the wall or switch/hub device port.

Note The IP phone should be used with Yealink original power adapter (5V/600mA) only. The use of the third-party power adapter may cause the damage to the phone.

Power over Ethernet

With the included or a regular Ethernet cable, the SIP-T21P E2 IP phone can be powered from a PoE-compliant switch or hub.

15

User Guide for the SIP-T21(P) E2 IP Phone

To connect the PoE for the SIP-T21P E2 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 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.

Important! Do not remove power from the phone while it is updating firmware and configurations.

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 If your network does not use DHCP, proceed to Basic Network Settings on page 18.

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, IP mode and MAC address).

16

Getting Started

Phone status (e.g., product name, hardware version, firmware version, product ID, MAC address and device certificate status).

Account status (e.g., register status of SIP accounts).

Note You can view device certificate status via phone user interface only.

To view the phone status via phone user interface:

1.Press , or press Menu->Status.

2.Press or to scroll through the list and view the specific information.

To view the phone status via web user interface:

1.Open a web browser of your computer.
