3.4 Setting SCSI Bus Termination
A set of terminating resistors must be either physically installed or software
enabled on the first and last physical device on the SCSI bus. You may have to
change the termination on the host adapter module and on some of the SCSI
devices.
1. Determine which two SCSI devices (including the host adapter) are at each
end of the SCSI bus. Install or enable termination on these two devices.
2. Disable termination on all other devices on the SCSI bus.
3. If one 8-bit and one 16-bit connector are used in a single-ended SCSI bus
application, the upper 8 bits of the default termination setting must be
terminated using the flash EEROM Configuration Utility (see Chapter 4).
The following paragraphs contain more information about device termination.
3.4.1 SCSI Device Termination
Refer to the SCSI device manufacturer’s documentation to determine how a
particular device’s termination is enabled or disabled.
