POWER GRN:	Blinking: Initializing Steady On: Power-On/Ready	Power-off
*STATUS RED:	Module BIT (Attention required)	No Module BIT Attention Required

*Status LED operations: Unless otherwise specified, default Status LED operations is controlled by the Slot-1 SBC/Root Complex card over the internal I2C communications link and functionally defined by the customer applied software application (the register is 0x38).

Elapsed Time Counter (ETC)

Integrated within the SIU34S backplane is an Elapsed Time Counter (ETC) IC, which records the accumulated time that the elapsed time recorder’s Event pin has been held high (in 250 ms increments). The ETC is read by the Slot-1 SBC/Root Complex card over the internal I2C communications link (the register is 0x6B).

Basic Operations

The SIU34S is delivered as a tested unit. All pins and operation have been verified. It is recommended that Power and Ethernet connections be made to verify operation of the boards fitted within the SIU34S by making use of NAI’s Embedded Soft Panel based GUI sample application that can be utilized as a board level “exercising” tool (if the SIU34S card configuration supports). The example process below describes the use of NAI’s Ethernet communications software tool.

After applying appropriate power to the SIU34S, connect a host computer (laptop or similar running Windows or Linux), to the appropriate Ethernet enabled/configured board (configured/populated in slot 1) Port A or Port B. The selection of Ethernet Port A or B is dependent on Slot-1 OpenVPX board configuration.

Note

Ethernet port assignments, MAC address, and factory default IP address are indicated on the chassis label.

QUALIFICATION

The SIU34S has been designed to meet the following general specifications. Cooling type, size, weight, power and environmental characteristics may affect the program requirements and the specifications as applied. Contact factory for the SIU34S Qualification Test status.

HEAT DISSIPATION

The SIU34S is capable of dissipating up to a total of 125 Watts when properly mounted. Generally, the conduction cooled version thermal interface must be maintained at a temperature not to exceed 71°C. Other operating and environmental factors and variable must be considered when specifying for a higher-level system platform integration. The total SIU34S power dissipation is dependent on the configuration of the OpenVPX boards and power supply fitted in the SIU34S.

RELIABILITY

The reliability of the SIU34S is dependent on the configuration of the OpenVPX boards and power supply fitted within it. The Mean Time between Failures is for the SIU34S configured with chassis, backplane, EMI Filter and connectors.

MTBF

The Mean Time between Failures is configuration, environment, and temperature dependent. Please contact factory regarding calculations based on the specific configuration and program requirements.

SIGNAL PIN-OUTS

The following pinout tables provide a general use guideline AS AN EXAMPLE, ONLY. Pinout routing will be dependent on card type/configuration for optimal I/O usage. Consult NAI factory for assistance in determining specific configuration signal definitions as applicable.

General System Functions

PS-ON/OFF#

SIU34S PSU is strapped to be always “ON”. The unit will power-on if external +28V power is applied.

SYSRST#

[GND] or Logic-level “Low” (referenced to internal System GND of the SIU34S) initiates/applies an active low assertion to the OpenVPX SYSRST# signal on the cards. Applied and once released, this will effectively introduce a root ‘system/card’ reset. SYSRST# signal is typically accessed from the SLOT-1 card, J1 MIL-connector.

Note

SYSRST# function is dependent on slot 1 card type/configuration; SYSRST# is typically routed to the “MRSTn” reset input of the SBC (root-complex) /Slot-1 card. If/as applicable, the card issues the RSTn signal on the backplane to all other “end-point” cards within the chassis when SYSRST# is asserted.
