Page 17: Internal Scsi Devices
Internal SCSI Devices Install or enable terminators on the device that you plan to install at the end of the internal cable. Then remove or disable terminators on all remaining devices. On most internal SCSI devices, you control termination by setting a jumper or a switch, or by physically removing or installing a resistor module(s). - Page 18 AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Plug one end of the 50-pin or 68-pin internal SCSI cable into the host adapter’s internal SCSI connector. Use a SCSI cable with enough connectors to accommodate all of the internal devices you want to attach.
- Page 19 Plug the other end of the internal SCSI cable into the connector on the last internal SCSI device in the chain. This device must be terminated. Make sure the colored stripe on the side of the cable is aligned with pin-1 of the SCSI device’s connector. Figure 2-7.

Page 23: Configuring Scsi Devices
Configuring SCSI Devices Your host adapters can transfer data up to 40 MBytes per second on each SCSI channel when connected to devices on a wide bus that support UltraSCSI. UltraSCSI and non-UltraSCSI devices can coexist on the same cable, and each device can transfer data at its own negotiated or assigned transfer rate. -

Page 30: Configuring Scsi Channel Interface Definitions
AHA-2940UW/OF and AHA-2944UW/OF User’s Guide Configuring SCSI Channel Interface Definitions The following four options enable you to configure the SCSI channel interface: Host Adapter SCSI ID— This option allows you to select the single-chip host adapter’s SCSI Initiator ID. The default setting for all models is 7, which has the highest priority on the SCSI bus. - Page 31 Host Adapter SCSI Termination— This option enables you to configure the SCSI cable termination on the single-chip host adapter. The default setting for single-chip host adapters that support cable-sensing termination is Automatic. Host Adapter SCSI Termination is determined by which SCSI connectors on the single-chip host adapter have devices attached to them.
