Installing the Cisco Unified Wireless IP Phone 7921G Configuration Utility Software Package using the Wavelink Avalanche Server Console

Installing Firmware Release 1.1(1) on Cisco Unified Communications Manager

This section describes how to install firmware release 1.1(1) on Cisco Unified Communications Manager.


Caution If you update the Cisco Unified Communications Manager release, it could potentially cause a downgrade of the firmware release for wireless IP phones. Local Phone Book records might be erased with a firmware downgrade. If the firmware release to which the phones have downgraded does not support the current WLAN authentication scheme (such as EAP-TLS or PEAP), the phones will lose connectivity to the network. For more information, see EAP-TLS and PEAP Support.

EAP-TLS and PEAP Support

Cisco Unified Wireless IP Phone 7921G firmware version 1.1.(1) supports advanced wireless security features such as EAP-TLS and PEAP. If you use EAP-TLS or PEAP for authentication, it is highly recommended that you do not downgrade the firmware because the authentication settings will not be valid on firmware releases prior to 1.1(1) and the phones will lose connectivity to the network.

If you must downgrade the firmware, you need to disable any network profiles that use EAP-TLS and PEAP.

If you upgrade to firmware version 1.1(1) again after a downgrade, reconfigure the EAP-TLS and PEAP settings, including any user installed certificates required for authentication.


Note If you upgrade the IP Phone firmware release from version 1.0 to 1.1(1), the call history data will be erased for firmware release 1.0.


Minimum Firmware Requirement

The new Cisco Unified Wireless IP Phone 7921G requires firmware release 1.0(4) or later. You cannot downgrade to a firmware release earlier than 1.0(4) on phones with the following part numbers:

74-4953-04

74-4954-04

74-4955-04

74-4956-04


Note To see the part number, first remove the battery. Look for the phone part number on the body of the phone. Do not use the part number on the battery.
