•Section 3.2, “Operational Environment,” page 3-4

•Section 3.3, “Subsystem ID and Subsystem Vendor ID,” page 3-9

3.1Physical Environment

This section discusses the physical, electrical, thermal, and safety characteristics of the LSI20160. Additionally, this board is compliant with electromagnetic standards set by the FCC.

3.1.1 Physical Characteristics

The dimensions of the LSI20160 are 4.721 x 2.536 inches. Edge connector J1 makes the PCI connection. The component height on the top and bottom of the LSI20160 follows the PCI speciﬁcation.

Connector J4 is a 68-pin high density connector that makes the internal SCSI connection. Connector J2 is a 68-pin VHDCI connector that makes the external SCSI connection. The J2 connector extends through the standard bracket, which is attached to the face of the connector outside of the cabinet where the LSI20160 is installed. Connector J3 provides connection to the computer’s drive activity LED. It is a 4-pin, one-row, right-angle header.
