Jumper Method
This method should only be attempted if the present software in the unit is not functioning sufficiently
enough to allow the user to access the UPGRADE FIRMWARE item on the Setup menu. This method
requires the unit to be powered down, the top cover removed, and the jumpers J27 and J11 on the Mid
plane board be placed in the programming position. Then reapply power to the unit and the unit should
automatically enter programming mode. Proceed to section 4.3.3 for information about uploading the
firmware using WINISP. When finished programming the unit, power down the unit, return the jumpers to
their original positions before re powering up the unit.
