current limiting resistor is included on the A33606-PCI-60-6A. Therefore, an external current
limiting resistor is NOT required.
Power Fail Input
The Power Fail Input is a 5V tolerant input dedicated to indicate that a Power Failure has occurred. Many
times, this indicates that one of the redundant supplies has reported a failure or has stopped functioning.
When this signal is asserted high, the following events occur:

The enclosure fault LED is asserted on the front panel of the A33606-PCI-60-6A.

The Power Fail LED signal is turned on.

The FAIL bit in the power supply SES element is asserted.

The status of the power supply SES element is changed to CRITICAL.

The status of the enclosure SES element is changed to CRITICAL.
