Step 5: SCSI Termination
Correct SCSI termination procedures require that the first and last
devices on the SCSI bus be terminated. If the first or last device is not
terminated, or if devices other than the first and last are terminated,
erratic SCSI bus performance may occur. Typically, the system or host
adapter (SCSI card inside the PC) is the first device and is already
terminated. When installing the RM4000 on a SCSI bus with other
devices, be sure to observe the above rules with all devices on the SCSI
bus. Consult your system and/or host adapter manual for additional
information on correct termination procedure.
Caution
Proper termination and SCSI-3 compliant cables are
required for the system to operate correctly. An external
SCSI terminator and a SCSI-3 compliant cable are
included with the UltraTrak.
SCSI Terminator
When the UltraTrak is the last SCSI device in the chain you must install
the Promise-supplied (or equivalent) external SCSI terminator on the
SCSI Output Connector. See Figure 5.
