Elite 9 Installation Guide, Rev. B 19 Setting the SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system’s SCSI controller usually uses the highest-numbered ID available (ID7 in non-wide sys- tems); therefore the lower-numbered SCSI IDs are nor- mally used for the other SCSI devices such as this Elite disc drive[...]
