(#5741) IBM Single Bus Ultra320 SCSI Repeater Card

The Single Bus Ultra320 SCSI repeater card provides the paths to transmit the differential SCSI signal from a cable to the DASD backplanes contained in the IBM 7031 Model D24 Ultra320 Expandable Disk Storage Drawer.

The Ultra320 SCSI Repeater Card provides the following functions:

• Provide SCSI enclosure services for all disk drives
• Read power supply unit Vital Product Data ( VPD)
• Monitor power line voltage EPOW (Early Power Off Warning) signals from the power supplies and assert SCSI reset to prevent data corruption during power failures.
• Detect hot plugged disk drives and power them on on automatically
• Separate power partitions to each individual drive preventing cage power faults for a single drive fault
• Provide cage power on commands when any attached host adapter is active
• Redrive the SCSI bus to allow SCSI cable lengths up to 20 meters
• Provide SCSI bus terminations for host and drve busses
