required to establish a direct (out-of-band) management connection to the DS4800
Storage Subsystem.

Configuring the storage subsystem

You must configure the storage subsystem configuration after you install the storage
subsystem in a rack cabinet. Use the information in the following sections to
configure your storage subsystem configuration.

Storage subsystem management methods

Before you configure the storage subsystem, determine which method of storage
subsystem management you want to use. You can manage the storage subsystems
in either of two ways: host-agent (in-band) management or direct (out-of-band)
management.
For more information on setting up in-band or out-of-band management
connections, refer to the DS4000 Storage Manager Installation and Support Guide
for the operating system of the host computer that will be used to manage the
DS4800 Storage Subsystem.
Important: If the operating system of the host server to which the storage

the cable connection is rotated correctly to match the alignment of the port
on the RAID controller. Do not force-fit.

host type. The server will then be able to recognize the storage
subsystem correctly for host-agent (in-band) management.
