Ultra Wide SCSI
The Workgroup Server 9650 233 and 9650 350 ship with a PCI Ultra SCSI JackHammer SE card pre-installed. This card is a high performance, single-ended, accelerated PCI to SCSI host adapter card that dramatically increases performance of SCSI devices connected to it. The JackHammer SE card is a PCI device that creates a high-speed interface between the CPU and disk drive. The JackHammer can transfer data through the Ultra SCSI-3 portion of the card at rates up to 40 MB s as allowed by the SCSI-3...
Replacement Caution Ire
The DIMM is keyed so that it fits into the DIMM slot only one way. Be sure to align the notches in the DIMM with the small ribs inside the slot. Replacement Note Push down firmly and evenly on the DIMM until you hear it snap into place. The internal hard disk drive SCSI ID 0 is connected to the Ultra Wide SCSI-3 bus. The internal hard disk drive SCSI ID 0 is connected to the Ultra Wide SCSI-3 bus. You can install a SCSI device in this expansion bay and connect it to the Ultra Wide SCSI-3 bus....
Rear Panel
Before you begin, remove the following 1 Using a flat-blade screwdriver, release the top five latches, two side latches, and two bottom latches on the rear panel. 2 Remove the rear panel from the computer.
