Installation and Configuration
•
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.
Note
If both system fans or the power supply fan fails the chassis will shut down
automatically, preventing the chassis and modules from damage due to overheating.
Remote Voltage Monitoring and Control
The NI PXIe-1062Q 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.
