If you use this connector, theIMM cannot be accessed directly from the production network. A dedicatedmanagement network provides additional security by physically separating themanagement network traffic from the production network. You can use theSetup utility to configure the server to use a dedicated systems-managementnetwork or a shared network.v Video connector: Connect a monitor to this connector.
