Procedure: Finding the status of Ethernet connections
This procedure explains how to find the status of the Ethernet connections when you cannot connect.
About this task
Ethernet port 1 must be connected to an active port on your Ethernet network. Determine the state of the Ethernet LEDs by using the following methods:
- If the node machine code is active on the node, use the USB flash drive to obtain the most comprehensive information for the node status. The status, speed, and MAC address are returned for each port. Information is returned that identifies whether the node is the configuration node and whether any node errors were reported.
- Examine the LEDs of the Ethernet ports. For 1 Gbps ports, the link is connected at 1 Gbps, and the link state LED will be ON. For 10 Gbps ports, the link LED should be ON.
Procedure
If your link is not connected, complete the following actions to check the port status each time until it is corrected or connected.
- Verify that each end of the cable is securely connected.
- Verify that the port on the Ethernet switch or hub is configured correctly.
- Connect the cable to a different port on your Ethernet network.
- If the status is obtained using the USB flash drive, review all the node errors that are reported.
- Replace the Ethernet cable.
- For the 10 Gbps Ethernet port, replace the small form-factor pluggable (SFP) transceiver.
- If it is a 1 Gbps port that is not working, follow the hardware replacement procedure for a node canister. If it is a 10 Gbps port that is not working, follow the hardware replacement procedure for a 10 Gbps Ethernet host interface adapter.
