SCSI Termination The SCSI channels on the MegaRUM motherboard use active termination for each SCSI channel. You must terminate the SCSI bus properly. The SCSI bus on each SCSI channel is an electrical transmission line and it must be terminated properly at both ends to minimize reflections and losses. You complete the SCSI bus by setting termination at both ends
