The call is muted.
The above introduces the default LED status. The status of the power indicator LED is
configurable via web user interface. For more information, contact your system administrator.
Two ways to customize configurations of your SIP-T48S IP phone:
T
he user interface on the IP phone.
T
he user interface in a
web browser
on
your PC.
The hardware components keypad and touch 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, it is possible to use 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 tapping to access the phone user interface. The
Advanced 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 43.
For a better understanding of the menu structure, please refer to Appendix B – Menu Structure
on page 251.
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 when the phone is idle.
Enter the IP address (e.g., http://192.168.0.10 or 192.168.0.10 for IPv4;
http://[2005:1:1:1:215:65ff:fe64:6e0a] or [2005:1:1:1:215:65ff:fe64:6e0a] for IPv6) in the address
bar of a web browser on your PC. The default administrator user name and password are both
“admin” (case-sensitive).
The access to the Advanced settings of the Account or Network via web user interface may be
blocked by the web browser (e.g., Chrome, Firebox) if you have installed “Adblock Plus plugin”.

The main options you can use to customize the IP phone via phone user interface and/or via
web user interface are listed in the following table:

AC Power (Optional)
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.
The IP phone should be used with Yealink original power adapter (5V/2A) 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-T48S IP phone can be powered from a
PoE-compliant switch or hub.
