SATA II RAID Subsystem
User Manual 17
1.3.3 Terminators
Based on SCSI specifications, the SCSI bus must be terminated at both ends,
meaning the devices that are connected to the ends of the SCSI bus must have
their bus terminators enabled. Devices connected in the middle of the SCSI bus must
have their terminators disabled. Proper termination allows data and SCSI commands
to be transmitted reliably on the SCSI bus. The host adapter and the SCSI
devices attached to it must be properly terminated, or they will not work
reliably.
Termination means that terminators are installed in the devices at each end of the
bus. Some SCSI devices require you to manually insert or remove the terminators.
Other devices have built-in terminators that are enabled or disabled via switches or
software commands. Refer to the device’s documentation on how to enable or disable
termination.
Note: If your RAID subsystem is the last device on the SCSI bus,
attach the terminator included in the package to the Host
Channel A & B Out port before using the subsystem.
