SCSI
Connectors
Two identical 68-pin SCSI-P connectors on the array's controller board enable
connection to a SCSI bus from the host.
Activity LED A controller board activity LED (located next to the right-most SCSI-P
connector) lights when power is applied to the array dur i ng the fir st part of the
Built-In Self Test (BIST) until the microprocessor extinguishes it. This LED
also flashes on a BIST failure. After completion of BIST, it lights whenever
the controller board is busy with a SCSI command.
