User`s guide

Note

Controller shelf #4 can use 2.0 meter SCSI–2 cables to the front or back

shelves in an SW800-series data center cabinet.

• SCSI buses are internal to the backplane in an SW300-series desktop

enclosure. No device cables are required.

4.4 Unpacking Your Subsystem

When delivered, your controller subsystem is packed in a carton and attached to

a shipping pallet. Upon receipt of your subsystem, perform the following tasks:

• Check the carton and pallet for signs of shipping damage.

• Report any damage to Digital Multivendor Customer Services or the Digital

sales ofﬁce in your area and to the local carrier who delivered your equipment.

• Use standard practices found in the StorageWorks model-speciﬁc installation

and user’s guides (listed in the Related Documentation list in the preface of

this manual) to unpack and remove your subsystem cabinet from the shipping

pallet.

• Keep all packing materials and shipping labels for later use and reference.

• Remove and read your subsystem documentation before beginning the

installation process.

4.5 Installing a Preconﬁgured or CTO Controller Subsystem

You can order from several preconﬁgured controller subsystems offered by Digital,

or you can choose to order a controller subsystem conﬁgured (conﬁgured-to-order

[CTO]) to your speciﬁc needs. Appendix A lists the order numbers for some of the

available options and CTO subsystems. Call your Digital sales ofﬁce for the most

up to date option and order numbers.

The HS array controller subsystems are available in large SW800-series data

center cabinets or smaller SW500-series cabinets, as well as SW300-series

deskside RAID enclosures. Each subsystem comes with a speciﬁed number of

HS array controllers and cache modules, power supplies, storage shelves with

storage devices, and device cables (if applicable). Some systems come with host

port cables. Ask your Digital sales representative for details about ordering host

port cables. You are encouraged to order preconﬁgured or CTO subsystems for

simplicity of subsystem installation.

If you choose to conﬁgure your own controller subsystem, see Chapter 3 for

conﬁguration rules and restrictions.
