IBM i Power 6, 8204 (#5742) IBM Dual Bus Ultra 320 SCSI Repeater Card</p><p>(Refurbished Condition Only as of November 26, 2010)</p><p>The Dual Bus Ultra 320 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 Ultra 320 Expandable Disk Storage Drawer or the #5786 TotalStorage EXP24 Disk Drawer. This high availability dual initiator feature allows the connection of two adapter cards to a SCSI group. The high availability SCSI connection feature can be used on any or all of the drive groups in the 7031 Model D24 and feature #5786 in conjunction with other drive groups in the enclosure using the standard IBM Single Bus Ultra 320 SCSI Repeater Card (FC #5741). The Dual repeater option can also be used to connect all 12 of the front drives or all 12 of the rear drives into a single SCSI bus of 12 drives.</p><p>The Ultra 320 SCSI Repeater Card provides the following functions:</p><p>Provide SCSI enclosure services for all disk drives</p><p>Read power supply unit Vital Product Data ( VPD)</p><p>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.</p><p>Detect hot plugged disk drives and power them on on automatically</p><p>Separate power partitions to each individual drive preventing cage power faults for a single drive fault</p><p>Provide cage power on commands when any attached host adapter is active</p><p>Redrive the SCSI bus to allow SCSI cable lengths up to 20 meters</p><p>Provide SCSI bus terminations for host and drve busses</p><p>Attributes provided: SCSI Bus connection</p><p>Attributes required: IBM 7031 Model D24 SCSI Disk StorageDrawer or a #5786 TotalStorage EXP24 Disk Drawer.</p><p>For 8204-E8A: IBM i Power 6, 8204 (#5742)</p><p>Minimum required: 0</p><p>Maximum allowed: 91 (Initial order maximum: 91)</p><p>OS level required: IBM i V5R4 with V5R4M5 Machine Code, or later.</p><p>Initial Order/MES/Both/Supported: Both</p><p>CSU: Yes</p><p>Return parts MES: No
