A.1 Physical Environment
This section discusses the physical, electrical, thermal, and safety
characteristics of the SYM22902 host adapter board. Additionally, this
board is compliant with electromagnetic standards set by the FCC.
A.1.1 Physical Characteristics
The dimensions of the SYM22902 host adapter board are approximately
6.60 x 2.53 inches. PCI connection is made through edge connector J1.
The component height on the top and bottom of the SYM22902 follows
the PCI Local Bus Specification, Revision 2.2 standard.
Internal 16-bit SCSI connection is made through the 68-pin high density
connector J4 for Channel B. External SCSI connection is made through
the 68-pin VHDCI connector J2 for Channel A.
The J2 connector extends through the Low Profile PCI (LPPCI) or
ISA/EISA bracket, which is attached to the face of the connector outside
of the cabinet where the SYM22902 is installed. The J3 connector is
used to connect the Busy LED. It is a 4-pin one row right-angle header
for both Channel A and Channel B.
