Power Inhibit Switch LED Indicator
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.
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.
