Identifying the Appliance’s Management Interface
Access: Admin
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:
Step 1 From the main menu, select 1 IP Configuration.
Step 2 Select the appliance’s management interface (generally eth0).
Step 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.
Step 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.
Step 5 When prompted, confirm your settings.
If prompted, confirm the IP address assigned to the appliance’s management interface.
