Action
1. Check the two indicators on the left and right corners of the NIC connectors on the system's back panel (see Figure 5 -1 ).
The green link indicator on the left side of the connector shows that the adapter is connected to a valid link partner. The amber activity indicator is on if
network data is being sent or received.
l If the link indicator is not on, check all cable connections.
l Try changing the auto-negotiation setting, if possible.
l Try another port on the switch or hub.
