If the Power Fail Input returns to an unasserted state (low), the error conditions are removed and the
A33606-PCI-60-6A stops reporting any errors (assuming no other error conditions exist).
HDD Fault LED
If any of the hard drives connected to the A33606-PCI-60-6A enter a fault condition, the HDD Fault LED
output signal is asserted high, illuminating an LED. The LED, if utilized, should be connected as shown
below. A 220

current limiting resistor is included in the circuit.
GPIO1 and GPIO4
GPIO1 and GPIO4 can be utilized for additional enclosure service I/O such as intrusion detection, additional
LEDs, alarm, door lock, etc. Default firmware does not utilize these signals. Contact Astek with your
requirements to obtain a customized configuration to utilize these pins.
Switch and LED Sink – Special Purpose Crypto Erase Pins
The Switch and LED Sink pins are used for the Crypto Erase Function. Please refer to Section 5 for more
details on both the Crypto Erase function and these special purpose pins.
Temperature Sensor Header
An external temperature sensor can be connected to J39.
The table below shows the pinout of the temp sensor connector.

This header is designed work with remote diode sensors or diode-connected transistors such as substrate
transistors on ICs. Astek provides a temperature probe cable, part number A40100-CBL-04, that is
supported by the A33606-PCI-60-6A. Alternately, temperature sensors on other boards in the system can
be monitored if they contain a diode or transistor sensor.
The temperature sensors are monitored through SCSI Enclosure Services (SES). Additional information on
SES is located in the SCSI Enclosure Services (SES) Section.
Fan Headers
There are 4 connectors for fan attachment on the A33606-PCI. One of the connectors (J33) is reserved for
the heatsink fan that cools the expander. The remaining 3 connectors (J14, J15, J20) support 3-pin fans
with tachometer or 4-pin fans with tachometer and PWM control.
