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

Refer to the Compaq StorageWorks Model 2100 and 2200 UltraSCSI Controller User

Guide, Compaq StorageWorks Enclosure 4200 Family LVD Disk Enclosure User

Guide, and Compaq StorageWorks Enclosure 4300 Family LVD Disk Enclosure User

Guide the 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 documentation for

further information.

3. Install the elements. Install the disk drives. Make sure you install blank panels in any

unused bays.

NOTE: 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).

4. Connect the six VHDCI UltraSCSI bus cables between the controller and disk

enclosures as shown in Figure 3–1 for a dual bus system and Figure 3–2 for a single

bus system. Note that the supported cable lengths are 1, 2, 3, 5, and 10 meters.
