Specific rules are given to make the installation and management of SCSI devices easier
and obtain the best performances.
• Install the system disk drive in the upper slot of Area 5 of the base unit
• Install devices beginning always from the upper free slot inside the area
• Within the disk configuration of Areas 3 and 2, install 18G byte disks, if any, according to
the following sequence:
– Area 3:
– top (ID 0)
–
middle (ID 1)
–
low (ID 2)
–
Area 2:
–
top (ID 8)
– low (ID A)
– middle (ID 9)

A mix of media drives and hard disk drives inside the same area is not allowed.
Refer to SCSI-ID Configuration , on page 5-10, for details about the SCSI-ID identification
