The CD also includes the DS4000 Storage Subsystem controller firmware.
Controller firmware version 6.23.xx.xx or higher, which supports the
attachment of EXP810, is on the DS4000 Storage Manager version 9.23
release 1 CD or can be downloaded from the IBM support Web site for
DS4000 storage products:
www.ibm.com/servers/storage/support/disk/
Note:
Depending on your DS4800 model, you may need to purchase the
appropriate host software kit for your host server operating system.
Contact your IBM representative or reseller for more information.

Continue with “Preparing the site.”
Preparing the site
The floor area at the installation site must provide the following conditions:
v Sufficient space to install the DS4800.
v Enough stability to support the weight of the fully configured DS4800 and
associated systems. A fully configured DS4800 weighs 36.52 kg (80.7 lb).
Ensure
that all requirements, such as floor space, air conditioning, and electrical
service, have been met. Other site preparation activities include the following tasks:
v To ensure that there is enough room to move around the cabinet and install
modules, clear space at the installation area.
v Install uninterruptible power supply (UPS) devices.
v If applicable, install host bus adapters (HBAs), switches, or other devices.
v Route interface cables from the hosts or switches to the installation area.
v Route main power cords to the installation area.
For
information on interface cables and connections, see Chapter 3, “Cabling the
storage subsystem,” on page 47.
Continue with “Preparing the rack cabinet.”
Preparing the rack cabinet
Important: Before you install the DS4800 in a rack cabinet, keep in mind the
following considerations:
v Review the documentation that comes with your rack cabinet for safety and
cabling considerations.
v Install the DS4800 in a recommended 22° C (72° F) environment.
v To ensure proper airflow, do not block the air vents; at least 15 cm (6 in.) of air
space is required. Review the important information in “Heat output, airflow, and
cooling” on page 29.
v To ensure rack stability, load the rack cabinet starting at the bottom.
v If you install multiple components in the rack cabinet, do not overload the power
outlets.
v Always connect the storage subsystem to a properly grounded outlet.
v Always connect the IBM-certified rack power distribution units (PDUs) to at least
two independent power circuits or sources.
Complete
the following steps to prepare the rack cabinet before you install the
DS4800:
1. Move, unpack, and level the rack cabinet at the installation site (if needed).
