SCSI Connector
This section describes how to configure the jumpers on Atlas 10K II Ultra 160/m
disks with 68-pin SCSI interface connectors. The following features are jumper-
selectable:
•
TERMPWR
• SCSI ID
• Write Protection

• Remote LED displays (BUSY and FAULT. Note that the FAULT LED
illuminates when any diagnostic or functional failure occurs that prevents the
drive from performing logical I/O.)
