Systems-mamagement Ethernet connector
Use this connector to manage the server, using a dedicated management
network. If you use this connector, the IMM cannot be accessed directly
from a production network. A dedicated management network provides
additional security by physically separating the management network traffic
from the production network. You can use the Setup utility to configure the
server to use a dedicated systems management network or a shared
network.
USB connectors
Connect USB devices to these connectors.
Ethernet connectors
Use either of these connectors to connect the server to a network. When
you use the Ethernet 1 connector, the network can be shared with the IMM
through a single network cable.

This LED is on the Ethernet connector. When this LED is lit, it indicates that
there is activity between the server and the network.
Ethernet link status LED
This LED is on the Ethernet connector. When this LED is lit, it indicates that
there is an active connection on the Ethernet port.
