7.5.3SCSI Connectors

The Server Board SE7520JR2 provides two SCSI connectors, one for each channel of the embedded LSI53C1030 SCSI controller. The external connector is routed to SCSI channel B, is a high density connector, and is found on the back edge of the server board. The internal connector is routed to SCSI channel A, is a standard 68 pin connector, and is located in the cutout on the edge of the server board. The pin-out for each connector is identical and is defined in the following table.
