Figure 5.1 Cabling layout (WIDE LVD drive)

Note 1. The SCSI bus can accommodate a maximum of 16 units on a WIDE (16-bit) bus, including the host processor, Ultrastar 15K73 units, and other SCSI devices.

Note 2. The WIDE LVD and SCA-2 LVD drives do not have the terminator on the drive, so an external terminator is required.
