Unformatted text preview: **25 M cable can be used only when connecting a single device Note: For bus width, 8 bits = “narrow” and 16 bits = “wide.” 8-bit SCSI always accepts 8 devices, 16-bit SCSI always accepts 16 devices. Note: HVD cable always has a max length of 25 meters. LVD cable always has a max length of 12 meters. Common SCSI ID Assignments: ID 0 – Bootable Hard Disk ID 7 – Host Adapter ID 3 – CD/DVD...
