1 225 Gb Ethernet port link and activity LED (green): Use this green LED to distinguish the network status.

  • Off: The network is disconnected.
  • Blinking: The network is accessing.
  • On: The network is established.

3 1 Gb Ethernet port link LED (green): Use this green LED to distinguish the network status.

  • Off: The network link is disconnected.
  • On: The network link is established.

4 1 Gb Ethernet port activity LED (green): Use this green LED to distinguish the network status.

  • Off: The node is disconnected from a LAN.
  • Blinking: The network is connected and active.

5 Check log LED (yellow): When this yellow LED is lit, it indicates that a system error has occurred. Check the XCC event log for additional information.

6 Identification LED (blue): Use this blue LED to visually locate the node among other nodes. This LED is also used as a presence detection button. You can use Lenovo XClarity Administrator to light this LED remotely.

7 Drive activity LED (green): If the LED is lit, it indicates that the drive is powered, but not actively reading or writing data. If the LED is flashing, the drive is being accessed.

8 Node power button with LED (green): Press this button to turn the node on and off manually. The states of the power LED are as follows:
  • Off: Power is not present or the power supply, or the LED itself has failed.
  • Flashing rapidly (4 times per second): The node is turned off and is not ready to be turned on. The power button is disabled. This will last approximately 5 to 10 minutes.
  • Flashing slowly (once per second): The node is turned off and is ready to be turned on. You can press the power button to turn on the node.
  • On: The node is turned on.
