This guide covers the process of troubleshooting network interface issues and the removal and replacement of NIC cards

Troubleshooting

Unplug the network cable(s) and plug them in firmly. If the network is still faulty, refer to Diagnostics.

Diagnostics

NIC Indicator

  1. Link indicator
  2. Activity indicator

Understanding Indicator Codes

  • Link and activity indicators are off. The NIC is not connected to the network.
  • Link indicator is green. The NIC is connected to the network at its maximum port speed (1 Gbps or 10 Gbps).
  • Link indicator is amber. The NIC is connected to the network at less than its maximum port speed.
  • Activity indicator is blinking green. Network data is being sent/received.

If the link and activity indicators are off while the cable is plugged in, you need to locate the faulty NIC. To do this, log in to the Gemini web interface and choose Node > Network > Ethernet. All the network interfaces are listed. If a NIC is not listed, then it is likely that it's faulty. f

Removing an External NIC

  1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and peripherals.
  2. Uncover the Gemini Appliance.
  3. Locate the appropriate NIC(s).
  4. Lift the expansion-card latch.
  5. Hold the NICs by its edges and remove it from the PCIe cards.
