*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 SIU34 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 stored on the chip from registers 0x0A-0x0D and read by the Slot-1 SBC/Root Complex card over the internal I2C communications link (the register is 0x6B).

Basic Operations

The SIU34 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 SIU34 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 SIU34 card configuration supports). The example process below describes the use of NAI’s Ethernet communications software tool.

After applying appropriate power to the SIU34, 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

HEAT DISSIPATION

The SIU34 is capable of dissipating up to a total of 130 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 SIU34 power dissipation is dependent on the configuration of the OpenVPX boards and power supply fitted in the SIU34.

RELIABILITY

The reliability of the SIU34 is dependent on the configuration of the OpenVPX boards and power supply fitted within it. The Mean Time between Failures is for the SIU34 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.

General System Functions

PS-ON/OFF#

SIU34 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 SIU34) 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.
