The programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature buttons. Most call functions, such as answering a call, placing a call on hold, and transferring a call, can be performed with the Cisco Unified IP Color Key Expansion Module. The following table lists the Cisco Unified IP Phones and the number of Key Expansion Modules that each model supports. Note For information about installing a wall mount kit for a phone that includes a Cisco Unified IP Color Key Expansion Module, see related links.

2 KEM Power Information Cisco Unified IP Phone model Supported KEMs 2 KEMs with 72 lines or buttons 1 KEM with 36 lines or buttons Related Topics Wall Mounts KEM Power Information The Cisco Unified IP Color Key Expansion Module for the Cisco Unified IP Phone 8961, 9951, and 9971 possesses the following power consumption and power scheme: Power consumption 48V DC, 5W per KEM Power scheme If the Cisco Unified IP Phone 8961, 9951, and 9971 uses AT PoE, at least one KEM can be powered up. If the phone uses a power adapter, three KEMs can be powered up for the Cisco Unified IP Phone 9971, two KEMs can be powered up for the Cisco Unified IP Phone 9951, and one KEM can be powered up for the Cisco Unified IP Phone If the Cisco Unified IP Phone 8961, 9951, and 9971 uses AF PoE, a KEM cannot be powered up. With AT power, the Cisco Unified IP Phones 9951 and 9971 can support two KEMs plus a USB headset or another USB device that is independently powered and only uses USB for signalling. The Cisco Unified IP Phone 9971 needs a power cube to support three KEMS. With AF power, the Cisco Unified IP Phones 9951 and 9971 need power cubes for any KEMS. The Cisco Unified IP Phone 8961 can support one KEM with CDP, AF power, and no power cube. Connect Single KEM to Cisco Unified IP Phone To connect a single KEM to the Cisco Unified IP Phone, follow these steps: 2 Cisco Unified IP Phone 8961, 9951, and 9971 Administration Guide for Cisco Unified Communications Manager 10.0

3 Connect Two or More KEMs to Phone Using KEM Spine Connector Position the phone so that the front of the phone is facing up. Connect one end of the KEM spine connector to the accessory connector on the Cisco Unified IP Phone. Connect the other end of the KEM spine connector to the KEM as shown in the following figure. Figure 1: Connecting the KEM Spine Connector to the Cisco Unified IP Phone and KEM Fasten the screws on the spine connector after connecting both the ends. Note You can use a coin or screwdriver to fasten the screws. Make sure that the sides of the screw heads are fully inserted into the spine connector cavity and tightened. Connect Two or More KEMs to Phone Using KEM Spine Connector To connect two or more KEMs to the Cisco Unified IP Phone, follow these steps: Cisco Unified IP Phone 8961, 9951, and 9971 Administration Guide for Cisco Unified Communications Manager

4 Set Up Key Expansion Module in Cisco Unified Communications Manager Administration Position the phone so that the front of the phone is facing up. Connect one end of the KEM spine connector to the accessory connector on the Cisco Unified IP Phone and the other end of the spine connector to a KEM, as seen in Connect Single KEM to Cisco Unified IP Phone, on page 2. The first KEM is now connected to the Cisco Unified IP Phone. Use a second KEM spine connector to connect the second KEM to the first KEM. Use a third KEM spine connector to connect the third KEM to the second (middle) KEM. The following figure shows a Cisco Unified IP Phone with three KEMs attached. Figure 2: Cisco Unified IP Phone with Three KEMs Attached Step 5 Fasten the screws on the spine connectors after connecting both the ends. Set Up Key Expansion Module in Cisco Unified Communications Manager Administration To configure the Cisco Unified IP Color Key Expansion Module on the Cisco Unified IP Phone, follow these steps: 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 Unified IP Color Key Expansion Module. Select and enter your search criteria and click Find. The Find and List Phones window appears with a list of phones that match your search criteria. 4 Cisco Unified IP Phone 8961, 9951, and 9971 Administration Guide for Cisco Unified Communications Manager 10.0

5 Access Key Expansion Module setup Step 5 Step 6 Step 7 Click the IP phone that you want to configure for the Cisco Unified IP Color 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, and choose the appropriate expansion module (or none ) for the Module 1, Module 2 and Module 3 fields, in that order. For the Module Load Name, enter the custom software for the appropriate expansion module, if applicable. The value that you enter overrides the default value for the current model. Ensure that the firmware load matches the module load. If the Module Load Name is left blank, the default load (the load bundled with the phone load) is installed. For the number of supported KEMs per phone model, see Cisco Unified IP Color KEM Setup Overview, on page 1. Ensure that the Side USB Port parameter is enabled. Note If the Side USB Port is disabled, the KEM does not work. Be sure to 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. Click Save. Access Key Expansion Module setup After you install one or more KEMs on the phone and configure them in Cisco Unified Communications Manager Administration, the KEMs are automatically recognized by the Cisco Unified IP Phone 8961, 9951, and When multiple KEMs are attached, they are numbered according to the order in which they connect to the phone. For example (see Connect Two or More KEMs to Phone Using KEM Spine Connector, on page 3): Key Expansion Module 1 is the KEM closest to the phone. Key Expansion Module 2 is the KEM in the middle. Key Expansion Module 3 is the KEM farthest to the right. You can select a KEM, and then choose one of the following softkeys: Exit: Returns to the Applications menu. Details: Provides details about the selected KEM. Setup: Allows you to configure the brightness of the selected KEM. Setting the brightness can also be done using the Preferences menu on the phone. For details, see the Cisco Unified IP Phone 8961, 9951, and 9971 User Guide for Cisco Unified Communications Manager (SIP). On the phone, press Applications and then press Accessories. All properly installed and configured KEMs display in the list of accessories. Cisco Unified IP Phone 8961, 9951, and 9971 Administration Guide for Cisco Unified Communications Manager

6 Upgrade Key Expansion Module Upgrade Key Expansion Module To automatically upgrade KEMs to the latest load, follow these steps: Power on the KEM, press Page 1, and do not release the key. When the LCD turns white, continue pressing Page 1 for at least one second. Release Page 1; LEDs should turn red. Immediately press Page 2 and continue pressing Page 2 for at least one second. Release Page 2; all LEDs should turn amber. Press Lines 5, 14, 1, 18, 10, and 9 in sequence. The LCD should turn blue, and the spinning loader icon displays in the center. The KEM starts to upgrade. Remove All Key Expansion Modules If you are removing one or more KEMs but still leaving one or more KEMs attached to the phone, see Connect Single KEM to Cisco Unified IP Phone, on page 2 or Connect Two or More KEMs to Phone Using KEM Spine Connector, on page 3 for instructions on how to connect the KEMs and phone based on how many KEMs remain. Also, go to Cisco Unified Communications Manager Administration and update the phone configuration file accordingly. Detach all existing KEMs from the phone. In Cisco Unified Communications Manager Administration, update the phone configuration file accordingly. Troubleshoot the Key Expansion Module Open a CLI.
