Introduction 47
Device Configuration
• Connect the OnBoard’s primary Ethernet port (eth0) to a local
management network and usually to the Internet, which extends the
management network to remote users whose access to devices is
controlled by the OnBoard.
Caution! If a device has a single Ethernet port, that port would need to be
attached to the production network, and the OnBoard would be need to be
configured to communicate with the device over the production network. With
this type of configuration, the OnBoard would be unable to provide the same
level of secure access to devices that it provides when it is configured as
recommended.
Figure 1-1 illustrates connecting two servers that have service processors,
with the service processors indicated by gray boxes. (The same
recommendations apply to connecting devices that do not have service
processors but that have dedicated Ethernet ports that provide access to the
devices’ consoles.) In Figure 1-1, note the following:
• The service processors’ (SPs) dedicated Ethernet ports are connected to
the OnBoard’s private Ethernet ports.
• The servers’ Ethernet ports are connected to the production network.
• The OnBoard’s primary Ethernet port (eth0) is connected to a
management LAN and to the Internet.
