Utility Server administration

Last Updated : Jun 05, 2026 |

You can enable the Utility Server when you install or upgrade Avaya Aura® Device Services. The Utility Server offers the following:

  • File server functionality. The Utility Server hosts various files that Avaya phones require to operate, such as firmware, configuration, or upgrade files.

  • Firmware management. The Utility Server provides the option to upload new phone firmware to the file server. You can also activate or deactivate the firmware.

Important:

  • You cannot enable the Utility Server using the Avaya Aura® Device Services web administration portal or configuration utility.

  • Although 46xxsettings.txt files are generated using the Dynamic Configuration service, these files are stored on the Utility Server. Therefore, you cannot generate 46xxsettings.txt files if you do not enable the Utility Server.

Utility Server in a cluster environment

The Utility Server is not clustered. When you upload files, such as firmware packages or upgrade files, on a Utility Server node, these files are not available on other cluster nodes. You must upload these files on all other Utility Server instances manually.

Note:

Configuration files generated using the Dynamic Configuration service become available on all cluster nodes automatically.

Browser support

You can access the Utility Server functionality using the following browsers:

  • Google Chrome

  • Internet Explorer

  • Microsoft Edge

Mozilla Firefox does not support certain features, such as backup and restore.
