9. SCSI Termination for Embedded System Board Channels (SISL)
Correct termination is critical for the SCSI channels. Termination on
the end of the bus connecting the disk drives (or other SCSI devices) is
required.
SCSI termination for the SCSI channels that reside on the system board
need to be properly controlled (notice the terminator “T” symbol) as
shown in Figure 2-23. You may also want to refer to documentation
that was provided with your system.
☛
Note
It is better to terminate the end of the SCSI bus itself
than it is to terminate the end device on the bus. This
allows hot swap devices to be added or removed from
the SCSI bus without affecting termination.
