Cisco IP Phone Key
Expansion Module Setup Overview
Key expansion modules add extra line appearances, speed dials, or programmable buttons to the phone. The programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature buttons
The slots in the side of the phone are designed only for use with the spine connectors on the key expansion module. Insertion of other objects permanently damages the phone.
When adding features to your expansion module, remember that each line button supports only one feature. You cannot add more features than the number of programmable line keys on your expansion module.

If you use a key expansion module with your phone then Power over Ethernet (PoE) is enough to power your expansion modules. But a power cube is needed for smartphone or tablet charging when your expansion module is attached.
A key expansion module uses 48V DC, 5W per module. If you are charging a smartphone or a tablet, note the following:
Side USB: Up to 500mA/2.5W charging
Back USB: Fast charging, Supports up to 2.1A/10.5W charging

The fast-charging feature on the back USB does not work when more than one expansion module is attached to a Cisco IP Phone 8861 using 802.3at PoE.
The fast-charging feature on the back USB doesn’t work when more than one expansion module is attached to a Cisco IP Phone 8861 unless Cisco Universal PoE (UPoE) is used.
Cisco IP Phone 8851 with 2 expansion modules will work on 802.3at PoE only with v08 or later hardware. You can find the phone version information on the lower back of the phone as part of the TAN and PID label. Version information is also located on the individual phone packaging.
Connect a Key Expansion Module to a Cisco IP Phone
If you want to install more than one expansion module, you repeat steps 7-9 to connect the other expansion modules together.Procedure
Unplug the Ethernet cable from the phone.
If installed, remove the footstand from the phone.
Locate the accessory connector covers on the side of the phone.
This diagram shows the location.
Remove the two accessory connector covers, as shown in the diagram.
The slots are designed for the spine connector only. Insertion of other objects will cause permanent damage to the phone.
Position the phone so that the front of the phone faces up.
Connect one end of the key expansion module spine connector to the accessory connector on the Cisco IP Phone.
Align the spine connector with the accessory connector ports.
Install the connector in the orientation shown in the following diagrams.
Firmly press the spine connector into the phone.
This diagram shows the spine connector.
This diagram shows the installation of the spine connector.
Connect the other end of the spine connector to the key expansion module as shown in this diagram.
Align the spine connector with the key expansion module accessory connector ports.
Firmly press the key expansion module into the spine connector.
(Optional)Use a second key expansion module spine connector to connect the second key expansion module to the first key expansion module.
(Optional)Use a third key expansion module spine connector to connect the third key expansion module to the second key expansion module.
Use a screwdriver to fasten the screws into the phone.
This step ensures that the phone and key expansion module remain connected at all times. This diagram shows the location of the screw holes on the phone and one key expansion module.
Make sure that the screws are fully inserted into the phone and tightened.
(Optional)Install the footstands on the phone and on the key expansion module, and adjust both footstands to rest evenly on the work surface.
Plug the Ethernet cable into the phone.
Set up the Key Expansion Module in Cisco Unified Communications Manager
Before you install an expansion module on a phone, configure it in the Product Specific Configuration area of your Cisco Unified Communications Manager Administration.
During the expansion module set up, you can configure the module to display on one-column or two-column mode.
In one-column mode, each row in the display corresponds to one line which is accessed by either the left or right-side buttons. In this configuration, the key expansion module displays 9 lines on page 1, and 9 lines on page 2. The following graphic shows the one-column mode.
In two-column mode, each of the buttons on the left and right of the screen is assigned to different lines. In this configuration, the key expansion module displays 18 lines on page 1, and 18 lines on page 2. The following graphic shows the two-column mode.
If the label is longer than the display space in both one- and two-column mode, the text contains an ellipsis (…).
In Cisco Unified Communications Manager Administration, choose
Device > Phone.
The Find and List Phones window appears. You can search for one or
more phones that you want to configure for the Cisco IP Phone 8800 Key Expansion Module.
Select and enter your search criteria and click
The Find and List Phones window appears with a list of phones that
match your search criteria.
Click the phone that you want to configure for the Cisco IP Phone 8800 Key Expansion Module. The Phone Configuration window appears.
Scroll down to the Expansion Module Information section on the right pane of the Phone Configuration window. Select the appropriate expansion module for the Module 1, Module 2 and Module 3 fields, in that order.
Select the phone button template (in the Device Information portion of the Phone Configuration window) that is configured to make full use of the KEMs attached to the phone.
Depending on your requirements, enable the One Column Display for KEM field for one-column mode, or disable the field for two-column mode.
Access Key Expansion Module Setup
After you install one or more key expansion modules on the phone and configure them in Cisco Unified Communications Manager Administration, the phone automatically recognizes the key expansion modules.
When multiple key expansion modules are attached, they are numbered according to the order in which they connect to the phone:
Key expansion module 1 is the expansion module closest to the phone.
Key expansion module 2 is the expansion module in the middle.
Key expansion module 3 is the expansion module farthest to the right.
You can select a key expansion module, and then choose one of the following softkeys:
Exit: Returns to the Applications menu.
Details: Provides details about the selected key expansion module.
Setup: Allows you to configure the brightness of the selected key expansion module. Setting the brightness can also be done using the Preferences menu on the phone.
On the phone, press Applications.
All properly installed and configured key expansion modules display in the list of accessories.
Reset the Single LCD Screen Key Expansion Module
If you are having technical difficulties with your Cisco IP Phone 8800 Key Expansion Module, you can reset the module to the factory default settings.
Restart the expansion module by disconnecting the power source, waiting a few seconds, and then reconnecting it.
As the expansion module powers up, press and hold Page 1. As the LCD screen turns white, continue pressing Page 1 for at least one second.
Release Page 1. The LEDs turn red.
Immediately press Page 2 and continue pressing Page 2 for at least one second.
Release Page 2. The LEDs turn amber.
Press Lines 5, 14, 1, 18, 10, and 9 in sequence.
The LCD screen turns blue. A spinning icon is displayed in the center of the screen.
The key expansion module resets.
