This upgrade process requires the server PC to boot from the USB upgrade memory key. This may require you to change the boot order set in the server PC's settings.

• The IP Office R12.0 images support booting from UEFI settings or from legacy boot options. Avaya recommends using UEFI.

To add other devices to the boot order, or to change the order of usage, you must change the server's boot settings. The method of accessing those settings varies between servers. Refer to the PC manufacturer's documentation.

• Typically, an option to access a server's BIOS settings appears briefly when the server PC is starting. For example, "Press Del for setup".

• Whilst the PC displays its BIOS settings, the boot process stops.

• To boot from a USB memory key, ensure the boot settings list the USB option before the server hard disk. If there are multiple USB options, select USB-FDD.

• The server's hard disk must remain in the list of boot devices. The server boots from the hard disk after you have completed the upgrade process.

  • If necessary for security, after upgrading the server to R12.0, access the boot settings again and remove the USB option from the boot order.
