In the following diagram, the T1 (SCSI terminator located near the
AIC-7892 SCSI controller) and T2 boxes are SCSI terminators. If an external
cable is connected, then the T2 termination is automatically deactivated.
By default, the internal SCSI bus is configured to run in Ultra 160 SCSI mode
(providing a maximum band-width of 160 MB/s). The user may configure
the SCSI system using the SCSISelect utility, included in the system BIOS.
Refer to
for details about the SCSISelect utility. This utility is also
described in more detail in the SCSI User’s Guide.
The Adaptec AIC-7892 Ultra 160 SCSI PCI controller is BBS compliant, but
does not support Hot Swap.
