1-4 System Overview
SCSI Adapter Board
Some systems may come with the Adaptec 2940 Ultra2 Wide SCSI board
installed in a PCI expansion slot. The SCSI adapter board brings the highest
performance SCSI I/O technology to the PCI local bus, transferring data up to a
maximum rate of 80 MB/second (up to a 133 MB host bus burst data rate). The
adapter board is compatible with all device protocols, including SCSI-1,
SCSI-2, Ultra SCSI, and Ultra2 SCSI.
For systems with the SCSI adapter board, the Adaptec SCSISelect configuration
utility comes installed on the system. The utility can be used to configure the
adapter board. The utility eliminates the need to use jumpers or terminators
when adding SCSI peripherals.
For systems with the adapter board and SCSI hard drive, a four-connector SCSI
cable is used to connect the drive to the adapter board. With this configuration,
up to four SCSI devices can be connected, including the factory installed
adapter board and SCSI hard drive. By purchasing additional SCSI interface
cables, up to a total of fifteen SCSI peripherals can be connected to the adapter
board.
Additional information on the SCSI adapter board is given in Section 2 of this
addendum.
EIDE and SCSI Hard Drives
All systems ship with a 3 1/2-inch hard drive, either EIDE or SCSI. Systems
might come with one of the following drives:
!
4.3-GB Ultra DMA 33, 5400 rpm

Further information on the SCSI hard drives is included in Section 2 of this
addendum. Information on the EIDE hard drives is included in the PowerMate
ES 5200 Series Service and Reference Guide.
