Step 1 Depending on how your Cisco Unified IP Phone is  
powered with one or two Expansion Modules, perform  
one of the following actions to connect the power  
supply:  
Your Cisco Unified IP Phone is powered over the  
Ethernet with one Expansion Module:  
Connect the power supply unit to the AC  
adapter port on the Expansion Module and  
plug the other end into a standard electrical  
power outlet in the wall.  
If your Cisco Unified IP Phone is powered over the  
Ethernet with two Expansion Modules:  
Connect the power supply unit to the AC  
adapter port on the Expansion Module closest  
to the Cisco Unified IP Phone and plug the  
other end into a standard electrical power  
outlet in the wall.  
If your Cisco Unified IP Phone is powered with a  
power supply unit with one Expansion Module:  
Reconnect the original Cisco Unified IP Phone  
power supply unit to the AC adapter port on  
the Cisco IP Phone and plug the other end into  
a standard electrical power outlet in the wall.  
If your Cisco Unified IP Phone is powered with a  
power supply unit with two Expansion Modules:  
Connect a second power supply unit to the AC  
adapter port on the Expansion Module closest  
to the Cisco Unified IP Phone and plug the  
other end into a standard electrical power  
outlet in the wall.

3 Features of the Cisco Unified IP  
Phone Expansion Module 7915  
The Cisco Unified IP Phone Expansion Module 7915 includes  
the following features.  
1
2
Phone screen—Displays the phone number, speed dial  
number (or name or other text label), phone service,  
phone feature or Privacy assigned to each button. Icons  
indicating line status appear similar to, and function the  
same as, those on the Cisco Unified IP Phone to which it  
is attached.  
1
16  
 
 
Lighted Buttons—12 buttons. Each button corresponds to  
one line (just like on the Cisco Unified IP Phone). The  
lights beneath each button indicate the state of the  
corresponding line as follows:  
2
Line available: light off  
Line in use by you: steady green light  
Line in use by someone else: steady red light  
Line ringing: flashing amber light  
You have a call on hold: flashing green light  
Someone else has a call on hold: flashing green light  
Call transfer: steady green light  
Shift Buttons—2 buttons. Each button corresponds to one  
page of 12 line keys. Page one is labeled with the number  
1 and page two is labeled with the number 2. The lights  
beneath each button indicate the state of the page as  
follows:  
3
Page is active: steady green light  
Page is inactive: light off  
A call is ringing on an inactive page: flashing  
amber light  
A call on hold on an inactive page: flashing  
amber light  
4 Using the Cisco Unified IP Phone  
Expansion Module 7915  
The Expansion Module 7915 functions as a line appearance or  
programmable button module, allowing you to keep track of  
calls in progress, calls on hold, and calls requiring transfer, or to  
access phone services. Most call functions, such as answering a  
call, placing a call on hold, transferring a call, and so on, are  
performed from the Cisco Unified IP Phone.  
17  
 
 
Note  
If the Expansion Module 7915 buttons are configured  
as phone features, they can be performed from the  
Expansion Module.  
Refer to the phone guide for your Cisco Unified IP Phone for  
instructions about using your phone.  
The following is a typical scenario when using the Cisco Unified  
IP Phone and Cisco Unified IP Phone Expansion Module 7915  
combination.  
You receive a call for your Director at extension 12345. You  
look at your Cisco Unified IP Phone Expansion Module 7915  
and see that your Director has a call in progress with another  
party and also has another call on hold. Looking down the  
Cisco Unified IP Phone Expansion Module 7915 screen, you  
note that another manager in your group has just completed a  
call and could possibly assist the incoming caller. You consult  
briefly with the incoming caller and then transfer the call to the  
manager.  
Keeping Your Call Information Private  
If Privacy is programmed for one of your buttons, you can keep  
your call information private from users who share your lines.  
If you see a button labeled “Privacy,” then this feature has been  
enabled for you by your system administrator. You toggle  
privacy on and off by pressing the Privacy button when  
receiving an incoming call. In addition, with Privacy enabled,  
other shared lines are blocked from joining your calls.  
Refer to the phone guide for your Cisco Unified IP Phone for  
more information.

Configuring the Buttons on Your Cisco  
Unified IP Phone Expansion Module 7915  
Similar to your Cisco Unified IP Phone, you can configure speed  
dial numbers or program buttons to access phone services on  
the Cisco Unified IP Phone Expansion Module 7915. Before  
you can do this, ask your system administrator for the following  
information to access your Cisco Unified Communications  
Manager User Options web page:  
The URL  
Your user name and password  
After you have this information, you can configure your speed  
dial numbers or program buttons to access phone services.
