Step 6 Set Termination - LSI MegaRAID Enterprise 1600 Hardware Manual

Step 6 Set Termination

Each MegaRAID SCSI channel can be individually configured for termination enable mode by
setting the J2, J3, J5, and J7 jumpers (see the previous page).
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 card to one end of the
SCSI cable for each channel and to connect an external terminator module at the other end of each
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.
