After installing this firmware update, all power must be drainedfrom the system to complete the installation. To drain all power from the system the system must beshut down, all power plugs must be removed from power, and the system must sit without power for atleast 15 seconds. A system reboot is NOT sufficient to complete this update. If the power drain process is not followed the updated firmware version will not be fully installed, even though it will appear to have been installed.
