CAUTION: Controller and disk enclosures have no power switches. Make sure the
controller enclosures and disk enclosures are physically configured before turning the
PDU on and connecting the power cords. Failure to do so can cause equipment
damage.
1. Be sure the enclosures are empty before mounting them into the rack. If necessary,
remove the following elements from the controller enclosure:
— Environmental Monitoring Unit (EMU)
— Power Supplies
— External Cache Batteries (ECBs)
—Fans
If necessary, remove the following elements from the disk enclosure:
— Power Supply/Blower Assemblies
—Disk Drives
— Environmental Monitoring Unit (EMU)
— I/O Modules

for further information.
2. Install brackets onto the controller enclosure and disk enclosures. Using two
people, mount the enclosures into the rack. Refer to the mounting kit

3. Install the elements. Install the disk drives. Make sure you install blank panels in
any unused bays.
Fibre channel cabling information is shown to illustrate supported configurations.
In a dual-bus disk enclosure configuration, disk enclosures 1, 2, and 3 are stacked
below the controller enclosure—two SCSI Buses per enclosure
(see Figure 3–1).
In a single-bus disk enclosure configuration, disk enclosures 6, 5, and 4 are
stacked above the controller enclosure and disk enclosures 1, 2, and 3 are stacked
below the controller enclosure—one SCSI Bus per enclosure (see Figure 3–2).
