This section discusses the physical environment associated with the
LSIU40SE. It includes a mechanical drawing of this board, which is
shown in Figure A.1. It also includes these topics:

•
Section A.2, "Operational Environment," page A-3
This section discusses the physical, electrical, thermal, and safety
characteristics of the LSIU40SE. Additionally, this board is compliant with
electromagnetic standards set by the FCC.
The dimensions of the LSIU40SE are 190 x 96.52 mm (7.50 x 3.80
inches). PCI connection is made through edge connector J1.
Internal 16-bit SCSI connection is made through the 68-pin high density
connectors J2 or J6. Internal 8-bit SCSI connection is made through the
50-pin low density connectors J4 or J8. External SCSI connection is
made through the 68-pin VHDCI connectors J3 or J7. The J3 and J7
connectors extend through the ISA/EISA bracket, which is attached to
the face of the connector outside the cabinet where the LSIU40SE is
installed.
The bracket is a standard ISA type with a cutout to accommodate the
connectors. The J5 and J9 connectors are for connecting the computer's
Busy LED. It is a 4-pin one row right-angle header wired in parallel with
the on-board LED. The component height on the top and bottom of the
board follows the PCI Local Bus Specification Revision 2.1 standard.
