Operational Environment 4-3
The following parameters define the storage and transit environmentfor
the LSI40909G-S:
•Storage Temperature:−45 °Cto+85°C (dry bulb)
•Relative Humidity Range: 5% to 95% noncondensing

4.1.4 Electromagnetic Compliance

Theseboards minimize electromagnetic emissions, susceptibility, and the
effects of electromagnetic discharge. The boards comply with ClassB
and carry markings for CE, VCCI, Canada, C-Tick, and FCC.

4.1.5 Safety Characteristics

The bare boards meet or exceed the requirements of UL flammability
rating 94 V0. The bare boards are also marked with the supplier’sname
or trademark, type, and UL flammability rating. Because these boards
are installed in a PCI bus slot, all voltages are below the SELV42.4 V
limit.
4.2 Operational Environment
Use the LSI40909G-S in PCI computer systems with an ISA/EISA
bracket type.The LSI Logic supplied FC BIOS and fir mware operatethe
boards. An on-board flash memory device and a serial EEPROM are
provided to allow BIOS code and open boot code support through PCI.

4.2.1 The PCI Interface

The PCI interface operatesas a 64-bit DMA bus master. Edge connector
J1 makes the PCI connection, which provides connections on both the
front and back of the board. The signal definitions and pin numbers
conform to the PCI Local Bus Specification, Revision 2.2. See that
specification for more details regarding the signal assignments. The
on-board regulators provide power to the board’s 3.3 V devices.
Note: The PCI + 3.3 V pins are tied together and decoupled with
high frequency bypass capacitors to ground. No current
from these + 3.3 V pins is used on the board. The board
derives power from the + 5 V pins, directly and through a
