3.1 Physical Environment
This section discusses the physical, electrical, thermal and atmospheric,
and safety characteristics of the LSI22915A. It should be noted that this
board is compliant with electromagnetic standards set by the FCC.
3.1.1 Physical Characteristics
The dimensions of the LSI22915A are approximately 4.2 by 8.4 inches
(106.68 by 213.36 mm). The LSI22915A interfaces with the PCI bus
through edge connector J6. The component height on the top and
bottom of the LSI22915A follows the PCI Local Bus Specification,
Revision 2.2, standard.
The LSI22915A has two internal 68-pin high density connectors: J3 for
SCSI Channel A, and J4 for SCSI Channel B. It also has two external
68-pin VHDCI connectors: J1 for SCSI Channel A, and J7 for SCSI
Channel B.
The J1 and J7 connectors extend through the ISA/EISA bracket, which is
attached to the face of the connector outside of the cabinet where the
LSI22915A is installed. The HDR2 connector is a 4-pin one row right-angle
header. It connects the Busy LED for both Channel A and Channel B.
