•
Section A.2, "Operational Environment," page A-3
This section discusses the physical, electrical, thermal, and safety
characteristics of the LSI8751SP. Additionally, this board is compliant
with electromagnetic standards set by the FCC.
The dimensions of the LSI8751SP are 127 x 82.55 mm (5.00 x 3.25
inches). PCI connection is made through edge connector J1.
Internal 16-bit SCSI connection is made through the 68-pin high density
connector J2. Internal 8-bit SCSI connection is made through the 50-pin
low density connector J4. External SCSI connection is made through the
68-pin high density connector J3. The J3 connector extends through the
ISA/EISA bracket, which is attached to the face of the connector outside
of the cabinet where the LSI8751SP is installed. The bracket is a
standard ISA type with a cutout to accommodate connector J3.
The J5 connector is for the Busy LED connection using a 4-pin one row
right angle header. The component height on the top and bottom of the
board follows the PCI Local Bus Specification Revision 2.0.
