Ethernet port connection from each controller is required to establish a direct
(out-of-band) management connection to the DS4200 Express Storage Subsystem.
Note: The alignment of the Ethernet and serial ports on controller A are opposite

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
DS4200 Express Storage Subsystem.
Important: If the operating system of the host server that the storage subsystem

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

logical drives are mapped to is not Microsoft Windows 2000 or Server
2003, then you have to make a direct (out-of-band) management
connection to the storage subsystem to set the correct host type first.
Then, the server will be able to recognize the storage subsystem
correctly for host-agent (in-band) management.
