The MCS server provides 6900 series handsets with firmware updates as part of it's configuration server role. The firmware configuration page provides an interface to see which firmware files are currently loaded onto the system and provides a utility to upload firmware updates.

MCS can manage multiple versions of firmware at the same time. Having multiple versions of firmware allows new firmware to be evaluated on a subset of handsets and/or models before it is rolled out system wide.

The table on the 6900 Firmware configuration page shows the firmware currently loaded. The table shows the following information:

• Version, the version number of the firmware in the format 'x.x.x.x'
• Phone Types, a list of models which the system has this firmware version for

Managing Firmware

New Firmware

New firmware is automatically added to new releases of MiVoice Office Application Suite and are automatically installed when upgrading. If firmware is released outside of a MiVoice Office Application Suite release then it may be necessary to upload new firmware.

New firmware will be provided in the form of a ZIP file. The name of the ZIP will correspond to the version number of the firmware and there will be a firmware file inside the ZIP for each model of handset.

To upload a new zip file, press the 'Upload Firmware' button. Press the 'Choose Files' button and browse for the new firmware ZIP file. When the upload has completed, the new firmware files will be copied to the following location:

"[ProgramData]\Mitel\Mitel Communication Service\Net Store\Firmware"

The table should automatically refresh and show the new firmware has been updated.

Deleting Firmware

When old firmware is no longer required, it can be deleted from the system. To do this, select a firmware from the table, then press the 'Delete' button. Firmware can only be deleted if it is not currently assigned to a model of handset.

Rolling Out Firmware

Firmware can be assigned at two levels:

• Model
• Phone

By default, all phones will be supplied with the firmware that matches the model number unless the firmware version has been overridden at phone level. Overriding firmware at phone level can be useful for testing a new release on one or a subset of handsets before rolling it out system wide. To override firmware at phone level, edit the required phone from the 6900 Phones configuration page.

Handsets will request new firmware at the following times:

• During the start-up sequence
• Upon resync (if configured)

The resync process is controlled by the 'Auto Resync Mode' and 'Auto Resync Time' configuration options. If set, the handsets will request new configuration files and firmware at the configured time.

If auto resync is disabled, handsets will need to be rebooted to force them to request new firmware.
