Direct (out-of-band) management method

This method uses Ethernet connections from a management station to each
controller. You must install at least one management station. The management
station can be the host or a workstation on the Ethernet network. A management
station will have the client software installed. Attach Ethernet cables to each
management station (one pair per storage subsystem). You will connect the cables
to each storage subsystem controller later when you install the storage subsystem.
Figure 53 on page 84 shows the direct (out-of-band) management method.
You can either use the default controller Ethernet IP addresses for out-of-band
connection or change the default controller Ethernet IP addresses by using
Dynamic Host Configuration Protocol (DHCP) or Storage Manager client. Refer to
the DS Storage Manager Installation, User's and Maintenance Guide for the
applicable operating system for more information about setting the management
connections and installing the DS5020 storage subsystem management software.
For a listing of default IP addresses, see "Connectors, switch, and enclosure ID" on
page 10.
Note: Do not connect the storage subsystem Ethernet ports to a public network or
public subnet. Create a private network between the storage subsystem and
the management station.
