User`s guide

• Measure cabinet capacities by the number of individual shelves that can be

installed into the cabinet (for example, BA350–SB storage shelves).

• Abide by the cabinet-speciﬁc installation sequence to maintain gravitational

stability. Failure to follow the sequence may result in tipping over the

cabinet.

• Shelf conﬁguration rules apply to all cabinets unless otherwise noted. Shelf-

speciﬁc conﬁguration rules are in the StorageWorks Solutions Shelf and SBB

User’s Guide and in Chapter 3 of this manual.

• Switch-controlled input power is required for each shelf.

• Bulkhead input/output (I/O) connections for the shelves, the host computer,

and/or external controllers are provided.

• An SW800-series data center cabinet or an SW500-series cabinet does not

typically support dc power modules.

• Input power can be either 60 Hz or 50 Hz with the appropriate cabinet cable

distribution unit (SW800–AA or SW800–AB, and SW500–AA or SW500–AB).

• For the controller and storage shelves, a second cable distribution unit (CDU)

is required to support more than a single power supply per shelf.

4.6 Installation Instructions for Preconﬁgured and CTO

Subsystems

Installing a preconﬁgured or CTO HS array controller subsystem requires that

you follow the guidelines and procedures discussed in this section.

Preconﬁgured and CTO subsystems have all subsystem components preinstalled

(controller modules, cache modules, SCSI–2 device cables, storage shelves,

devices, power supplies, and so forth) except for the host port cables (for HSD30

and HSZ array controllers).

Note

Internal host port cables are included with HSJ array controllers.

(External CI cables must be ordered separately.) Host port cables must be

ordered separately for HSD30 and HSZ array controllers.

Therefore, you need to do only the following:

1. Unpack the subsystem and move it into place. Refer to cabinet-speciﬁc

installation guides for unpacking instructions.

2. Open the front and back doors of the cabinet.

3. Visually inspect all subsystem components to determine whether:

• All cables are seated properly

• All SBBs are seated properly

• All controller and cache modules are seated properly

• All shelf fans are seated properly

• All program cards are loaded properly
