Procedure: Finding the status of Ethernet connections

Use this procedure to find the status of Ethernet connections in the system when you cannot connect.

About this task

Ethernet port 1 of each node canister must be connected to an active port on your Ethernet network. You can determine the status of the Ethernet ports by using any of the following methods:
  • Connect a personal computer directly to the node by following Procedure: Accessing the service assistant from the technician port. In the service assistant, the status, speed, and MAC address for each port are shown in the Ports tab of the Node Details table. Any node errors are shown in the Node Errors table.
  • Use a USB flash drive to obtain node configuration information (see Procedure: Getting node canister and system information by using a USB flash drive). The results file contains the status, speed, and MAC address for each port; whether the node is the configuration node and if any node errors are being reported.
  • Examine the LEDs of the Ethernet ports. The Ethernet ports on the left end of the rear of each node canister are 1 Gbps Ethernet ports. For these ports, the link state LED is ON if the link is connected. If optional 10 Gbps Ethernet adapters are fitted, then the green link LED is ON if the link is connected. If optional 2-port 25 Gbps Ethernet adapters are present, the port status is green if the link is up and flashes green with link activity.

Procedure

  1. Verify that each end of the cable is securely connected.
  2. Verify that the port on the Ethernet switch or hub is configured correctly.
  3. Connect the cable to a different port on your Ethernet network.
  4. Replace the Ethernet cable.
  5. Review any node errors that are reported in the service assistant or on the USB flash drive. Follow fixing node errors for each node error that is reported.
  6. Follow the hardware replacement procedure for a node canister.
