A.1 Physical Environment

This section discusses the physical, electrical, thermal, and safety characteristics associated with the LSIU40HVD. The board is compliant with the electromagnetic standards set by the FCC.

A.1.1 Physical Characteristics

The dimensions of the LSIU40HVD are 190 x 96.52 mm (7.50 x 3.80 inches). PCI connection is made through the edge connector J1. Internal 16-bit SCSI connection is made through the 68-pin high density connectors J2 or J5. External SCSI connection is made through the 68-pin high density connectors J3 or J6. The J3 and J6 connectors extend through the ISA/EISA bracket, which is attached to the face of the connector outside of the cabinet where the LSIU40HVD is installed. The bracket is a standard ISA type with a cutout to accommodate the connectors. The J4 and J7 connectors are for connecting the computer’s Busy-LED. It is a 4-pin, one-row right-angle header wired in parallel with the onboard LED. The component height on the top and bottom of the board follows the PCI speciﬁcation.
