When connecting devices to the OnBoard, observe the following recommendations, which are illustrated in Recommended Device Configuration:
• Connect the main Ethernet port(s) on connected servers or devices to a production network, which must be accessible to all those who need to access the device.
• Connect the dedicated Ethernet port on each service processor or device to one of the OnBoard’s private Ethernet ports. The connections between the OnBoard and devices make up the management network.
• 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.Recommended Device Configuration 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 Recommended Device Configuration, note the following:
• The service processors’ (SPs) dedicated Ethernet ports are connected to the OnBoard’s private Ethernet ports.
• The OnBoard’s primary Ethernet port (eth0) is connected to a management LAN and to the Internet.
