A.1 Physical Environment
This section discusses the physical, electrical, thermal, and safety
characteristics of the LSIU80ALVD. Additionally, this board is compliant
with electromagnetic standards set by the FCC.
A.1.1 Physical Characteristics
The dimensions of the LSIU80ALVD board are 154.4 x 88.90 mm (6.00
x 3.50 inches). PCI connection is made through edge connector J1.
Internal SCSI connection is made through the 68-pin HD connector J2.
External SCSI connection is made through the 68-pin HD connector J3.
The J3 connector extends external to the cabinet through a bracket
attached to the board and the face of the connector. The bracket is a
standard ISA type with a cutout to accommodate connector J3.
The J4 connector is for connecting to the computer’s drive activity LED.
It is a 4-pin one row right angle header wired in parallel with the on-board
SCSI Activity LED.
The component height on the top and bottom of the board conforms to
the PCI Specification Revision 2.1.
