● If the issue persists after moving the cable to another port on the switch, review the switch logs and consult your switch
user manual.
If the event persists, gather logs, and then contact Technical Support for additional troubleshooting. For instructions on how to
gather cluster logs, see Gathering cluster logs.

One of the nodes in your cluster has lost external network connectivity.
Administrator action
Determine whether the issue is related to the cable or the node. Perform the following steps in the order listed. If the issue
resolves after a step, there is no need to complete the subsequent steps.
1. Verify the following connections:
● All of the cables in the rack and in adjacent racks are connected securely to the node and neither the cable nor the
connector is damaged.
● The cable is rated for the appropriate Ethernet speed.
● The switch port speed is set to the same or higher speed as the Ethernet cable.
● The switch port is set to the Full Duplex setting.
2. If the cable is connected securely, plug the cable into a different node that has a network port functioning at full speed and
that has an identical network configuration. When you plug the cable into the other node, leave the other end of the cable
plugged into the same switch port.
