Step 6 Set Termination
You must terminate the SCSI bus properly. Set termination at both ends of the SCSI
cable. The SCSI bus is an electrical transmission line and must be terminated properly to
minimize reflections and losses. Termination should be set at each end of the SCSI
cable(s), as shown below.
For a disk array, set SCSI bus termination so that removing or adding a SCSI device does
not disturb termination. An easy way to do this is to connect the MegaRAID Express 500
card to one end of the SCSI cable and to connect an external terminator module at the
other end of the cable. The connectors between the two ends can connect SCSI devices.
Disable termination on the SCSI devices. See the manual for each SCSI device to disable
termination.
