Setting Up the Cisco Unified IP Color Key Expansion Module


The Cisco Unified IP Color Key Expansion Module (KEM) attaches to your Cisco Unified IP Phone 8961, Cisco Unified IP Phone 9951, and Cisco Unified IP Phone 9971 to add additional line appearances, speed dials, or programmable buttons to your phone.

You can add one Key Expansion Module (KEM) to the Cisco Unified IP Phone 8961 to add up to 36 extra lines or buttons, two Expansion Modules to the Cisco Unified Phone 9951 to add up to 72 extra lines or buttons, and three Expansion Modules to the Cisco Unified IP Phone 9971 to add up to 108 extra lines or buttons.

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.

Table 4-1 lists the Cisco Unified IP Phones and the number of KEMs supported by each model.


Note For information on installing a wall mount kit for a phone that includes a Cisco Unified IP Color Key Expansion Module, see the "Installing a Wall Mount for a Phone with a Key Expansion Module" section.

Installing a Key Expansion Module on the Cisco Unified IP Phone

This section contains the following topics:

Power Information

Connecting a Single KEM to the Cisco Unified IP Phone

Connecting Two or More KEMs to the Phone Using the KEM Spine Connector

Power Information

The Cisco Unified IP Color Key Expansion Module for the Cisco Unified IP Phone 8961, 9951, and 9971 have the following power consumption and power scheme.

Power Consumption

48V DC, 5W per KEM

Power Scheme

At least one KEM can be powered up if the Cisco Unified IP Phone 8961, 9951, and 9971 uses AT PoE.

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 8961.

A KEM cannot be powered up if the Cisco Unified IP Phone 8961, 9951, and 9971 uses AF PoE.

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 signaling.

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.

Connecting a Single KEM to the Cisco Unified IP Phone

To connect a single KEM to the Cisco Unified IP Phone, perform the following:

Procedure


Step 1 Position the phone so that the front of the phone is facing up.

Step 2 Connect one end of the KEM spine connector to the Accessory Connector on the Cisco Unified IP Phone as shown in the Figure 4-1.

Step 3 Connect the other end of the KEM spine connector to the KEM as shown in the Figure 4-2.

Step 4 Fasten the screws on the spine connector after connecting both the ends.


Note You can use a coin or screwdriver to fasten the screws. The screws should be fastened to finger tight so that the sides of the screw heads are fully inserted into the cavity.

Connecting Two or More KEMs to the Phone Using the KEM Spine Connector

To connect two or more KEMs to the Cisco Unified IP Phone, perform the following:

Procedure


Step 1 Position the phone so that the front of the phone is facing up.

Step 2 Connect one end of the KEM spine connector to the Accessory Connector on the Cisco Unified IP Phone (see Figure 4-1) and the other end of the spine connector to a KEM, as shown in the (Figure 4-1). The first KEM is now connected to the Cisco Unified IP Phone.

Step 3 Using a second KEM spine connector, connect the second KEM to the first KEM.

Step 4 (Optional) Using a third KEM spine connector, connect the third KEM to the second (middle) KEM. Figure 4-3 shows a Cisco Unified IP Phone with three KEMs attached.

Step 5 Fasten the screws on the spine connectors after connecting both the ends.

Configuring the 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, perform the following:

Procedure


Step 1 In Cisco Unified Communications Manager Administration, choose Device > Phone.

The Find and List Phones page appears. You can search for one or more phones that you want to configure for the Cisco Unified IP Color Key Expansion Module.

Step 2 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.

Step 3 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 this 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 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, refer to Table 4-1.

Step 4 Make sure the Side USB Port parameter is enabled.


Note If the Side USB Port is disabled, the KEM will not work.


Step 5 Be sure to select the phone button template (in the Device Information portion of the Phone Configuration window) that has been configured to make full use of the KEM(s) attached to the phone.

Step 6 Click Save.


Key Expansion Module Settings on the Phone

Once you have installed one or more KEMs on the phone and have configured them in Cisco Unified Communications Manager Administration, the KEMs are automatically recognized by the Cisco Unified IP Phone 8961, 9951, and 9971.

On the phone, press the Applications button and then press Accessories. All KEMs that have been properly installed and configured should appear in the list of accessories.

When multiple KEMs are attached, they will be numbered according to the order in which they are connected with respect to the phone. For example (refer to Figure 4-3):

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. This can also be done by means of the Preferences menu. For details, refer to the Cisco Unified IP Phone 8961, 9951, and 9971 User Guide for Cisco Unified Communications Manager, "Accessories" chapter, "Adjust the Brightness on the Cisco Unified IP Color Key Expansion Module" section.

Upgrading the Key Expansion Module

To automatically upgrade KEMs to the latest load, follow these steps:

Procedure


Step 1 Power on the KEM, press Page 1, and do not release. When the LCD turns white, continue pressing Page 1 for at least one second.

Step 2 Release Page 1; LEDs should turn red. Immediately press Page 2 and continue pressing Page 2 for at least one second.

Step 3 Release Page 2; all LEDs should turn amber.

Step 4 Press Lines 5, 14, 1, 18, 10, and 9 in sequence.

The LCD should turn blue, and the spinning loader is displayed in the center.

The KEM starts to upgrade.


Removing a Key Expansion Module

If you need to remove all existing KEMs from the phone, detach them from the phone, then go to Cisco Unified Communications Manager administration and update the phone configuration file accordingly.

If you are removing one or more KEMs but still leaving one or more KEMs attached to the phone, refer to the "Installing a Key Expansion Module on the Cisco Unified IP Phone" section for instructions on how the KEMs and phone should be connected based on how many KEMs will remain. Also, go to Cisco Unified Communications Manager Administration and update the phone configuration file accordingly.

Troubleshooting

To obtain KEM troubleshooting information, follow these steps:

Procedure


Step 1 Open a command line interface.

Step 2 Enter the following command to enter debug mode:

debugsh

Step 3 Enter ? to see all available commands and options.

Step 4 Use the applicable commands and options to find the KEM information desired.


To exit debug mode, either perform a Ctrl-C.
