The chassis power inhibit switch has an integrated LED. This LED 
indicates one of four different conditions:

•

If the inhibit switch LED is steady green (not flashing), the chassis is 
powered on and operating normally.

•

If the inhibit switch LED is flashing green, the air-intake temperature 
has exceeded the chassis operating range.

•

If the inhibit switch LED is flashing red, the power supply outputs are 
not within voltage regulation requirements.

•

If the inhibit switch LED is steady red, the system fans or power supply 
fan has failed. The remaining fans will automatically be driven high.

If two system fans or both of the power supply fans fail the chassis will shut down 

automatically, preventing the chassis and modules from damage due to overheating.

The NI PXIe-1065 chassis supports remote voltage monitoring and 
inhibiting through a female 9-pin D-SUB (DB-9) connector located on 
the rear panel. Table 2-1 shows the pinout of the 9-pin D-SUB (DB-9) 
connector.
