The PCI PRSNT1/ and PRSNT2/ pins are set to indicate a 7.5 W maximum configuration.

3.1.3 Thermal, Atmospheric Characteristics

The board operates in an environment defined by the following parameters:

• Temperature range: 5 to 55 ° C (dry bulb)

•Relative humidity range: 5 to 90% noncondensing

•Maximum dew point temperature: 32 ° C

3.1.4Electromagnetic Compliance

The board minimizes electromagnetic emissions, susceptibility to radio frequency energy, and the effects of electromagnetic discharge. The board meets the requirements of FCC and CISPR Class B limits and is marked with the FCC Class B ID: B8J8251AD.

3.1.5 Safety Characteristics

The bare board meets or exceeds the requirements of UL flammability rating 94 V0. The bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. Because this board is installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.

3.2 Operational Environment

The LSI8751D is designed for PCI computer systems with a standard bracket. The SDMS software operates the board, but the design of the board does not prevent the use of other software.

3.2.1 The PCI Interface

The PCI interface operates as a 32-bit DMA bus master. The connection is made through the edge connector J1, which provides connections on both the top and bottom of the board. The signal definitions and pin numbers conform to the PCI Local Bus Specification Revision 2.1 standard. The signal assignments are shown in Table 1.2 and Table 1.3.
