the Twin DisplayPort Input cards remain on in standby mode. When this option is enabled, only
reset the video source when the projector is AC cycled.
Environmental Board HW Version status item
displays Bad Power
At startup, the Environmental Board HW Version status item displays Bad Power.
Details
The environmental board (EVB) is not receiving 12V power from the low voltage power supply
(LVPS). 12V from the LVPS to the EVB is transmitted using two harnesses (P/N: 001-112012-XX
and 001-112021-XX or 001-112022-XX). These harnesses must be securely connected to the EVB.

Solution
Verify both the 001-112012-XX and 001-112021-XX (or 001-112022-XX) harnesses are securely
connected to the following:
• LVPS
• Each other
• EVB
