4.Connect cable BN21K-05 (HD68-pin straight-thru) to an end of the Y-cable just attached to your new server.

5.Remove the external terminator (H879AA) connected to the end of the Y- cable of the last server on the SCSI bus in your existing cluster.

6.Attach the terminator just removed, to the remaining end of the Y-cable connected to your new server.

7.Connect one end of cable BN21K-05 (HD68-Pin straight-thru) to the end of the Y-cable of the server from which the terminator was removed.
