Chapter ThreeInstallationUnpacking and InspectionThe carrier is responsible for damage incurred during shipment. In case of damage,have the carrier note the damage on both the delivery receipt and the freight bill,then notify your freight company representative so that the necessary insuranceclaims can be initiated.After opening the shipping container, use the packing slip to verify receipt of the indi-vidual items listed on the slip. Retain the shipping container and packing materialfor later use should return of the equipment to the factory be necessary.CAUTIONThe AHA-1740A/1742A/1744 is carefully designed to resist the effects of staticelectricity. However, like all electronic equipment, it can be damaged or its lifecan be shortened by unusual static discharges. Please take the proper precautionswhen handling the board. Keep the board in its conductive wrapping until it isready to be installed in your system. Be sure that the host computer and the per-sonnel handling the board are properly grounded while installing the board.InstallationThe following section details the installation procedure for the Adaptec AHA-1740A/1742A/1744 EISA-to-SCSI host adapter. The installation of the board consistsof unpacking the board, preparing the SCSI devices, installing the correct termina-tions, inserting the board into a full-length EISA-compatible connector, and connect-ing a SCSI cable from the onboard connector to a SCSI target. The system is thenpowered up, the microcode downloaded and the board configured for operation.The Adaptec AHA-1740A/1742A/1744 EISA-to-Fast SCSI host adapter has been de-signed to operate as shipped in standard EISA class computers. The board (or the sys-tem in which it is installed) is normally shipped with a configuration diskette whichpermits the board to be configured to the actual slot location in which it is installed.Unlike AT/ISA boards, but like Micro Channel boards, EISA boards do not normallyrequire hardware jumpers.Ensure that you have the correct version of the AHA-1740A/1742A/1744 for your sys-tem. The AHA-1740A/1742A support the more common single-ended SCSI interface.The AHA-1744 supports the differential interface, more common on SCSI peripheralson minicomputers. While the two use the same signal protocol, they are not electri-cally compatible.3-1
