Cisco Unified Wireless IP Phone 7921G Series Deployment Guide 81
To upgrade the phone firmware, run the executable for Cisco Unified Communications Manager version 4.1, 4,2 and 4.3 or
install the COP file for versions 5.0, 5.1, 6.0, 6.1, 7.0, 7.1, 8.0 and later.
For information on how to install the COP file on CM versions 5.0 and later, refer to the Cisco Unified Communications
Manager Operating System Administrator Guide at this URL:

During TFTP server download, the phone configuration file is parsed and the device load is identified. The phone
downloads the firmware files to flash if it is not running the specified image already.
Cisco Unified Communications Manager device load takes precedence over the TFTP firmware version.
The Load Server can be specified as an alternate TFTP server to retrieve firmware files in the Cisco Unified Wireless IP Phone
7921G product specific configuration in Cisco Unified Communications Manager Administration.
To install the firmware on Cisco Unified Communications Manager Express, extract the contents of the TAR file and upload
into the router’s flash. Each file will need to be enabled for TFTP download. Configure the phone load and reset the phones to
upgrade the firmware.
Example below:
tftp-server flash: CP7921G-1.4.1.LOADS
tftp-server flash:APPS-1.4.1.SBN
tftp-server flash:GUI-1.4.1.SBN
tftp-server flash:SYS-1.4.1.SBN
tftp-server flash:TNUX-1.4.1.SBN
tftp-server flash:TNUXR-1.4.1.SBN
tftp-server flash:WLAN-1.4.1.SBN

Web Interface
The phone firmware can be upgraded via the web interface by navigating to Phone Upgrade and browsing to the firmware TAR
file.
In order to access the Phone Upgrade menu, the web access must be set to “Full”.
Note: If the Cisco Unified Wireless IP Phone 7921G registers to Cisco Unified Communications Manager, web access to the
Cisco Unified Wireless IP Phone 7921G gets set to read-only mode. In this mode, firmware upgrades via the web interface are
not allowed.
Ultimately the Cisco Unified Wireless IP Phone 7921G will use what is set as the phone load in the Cisco Unified
Communications Manager.
