Identifying the Appliance’s Management Interface
The first step in running the restore utility is to identify the management interface on the appliance you want to
restore, so that the appliance can communicate with the server where you copied the ISO and any update files. If
you are using LOM, remember that the management IP address for the appliance is
not
the LOM IP address.
To identify the appliance’s management interface:
1.
From the main menu, select
1 IP Configuration
.
2.
Select the appliance’s management interface (generally
eth0
).
3.
Select the protocol you are using for your management network:
IPv4
or
IPv6
.
Options for assigning an IP address to the management interface appear.
4.
Select a method to assign an IP address to the management interface:
Static
or
DHCP
:
—
If you select
Static
, a series of pages prompts you to manually enter the IP address, network mask or prefix
length, and default gateway for the management interface.
—
If you select
DHCP
, the appliance automatically detects the IP address, network mask or prefix length, and
default gateway for the management interface, then displays the IP address.
5.
When prompted, confirm your settings.
If prompted, confirm the IP address assigned to the appliance’s management interface.
What to Do Next

Specifying ISO Image Location and Transport Method
After you configure the management IP address that the restore process will use to download files it needs, you
must identify which ISO image you will use to restore the appliance. This is the ISO image that you downloaded
from the Support Site (see
Obtaining the Restore ISO and Update Files, page 20
), and stored on a web server, FTP
server, or SCP-enabled host.
The interactive menu prompts you to enter any necessary information to complete the download, as listed in the
following table.
