Updating the MBU 400 System Firmware

To ensure that your MBU 400 System has the latest features installed, we recommend that you update the firmware once you have configured and set up the phone.

Updating the Firmware

When new software is available the handset display reads, “New firmware available.” To update the firmware from the handset do the following.

1.In Idle mode, press OK z to display the Main Menu.

2.Select Settings and press OK z.

3.Select System settings, and press OK z.

4.Select Firmware update, and press OK z.

The gateway proceeds to download the latest firmware from the configuration server and updates the gateway and the handset when successful.

The update time varies depending on the size of the update and the speed of your Internet connection. Handsets in the MBU 400 system can take 10 minutes each to update fully. During the update process the following steps are listed in the display:

Getting gateway

Updating gateway

Getting handset

Updating handset

Once a step is complete, a green checkmark appears next to the step. When the entire update has been successfully completed, the display reads Upgraded to <version number>.

Note: In some cases the handset may repeat the handset update. Ensure that the handset update has been completed (to 100%) at least once, then reset the MBU 400 base unit.

Note: While the update is in progress you cannot receive incoming calls or make calls, including emergency calls, on the phone. Also note that we recommend you do not reset the gateway during the installation process.

Changing Internet Settings

Through the handset you can access the Internet Settings menu. The settings located here are administrator settings, and should be set by your System Administrator. For more information see the Aastra MBU 400 Administrator Guide.
