Front LEDs
The following illustration shows LEDs on the front of the solution. By viewing the status of LEDs, you can often identify the source of the error.
| 1 RoT LED | 7 1 Gb RJ45 Ethernet port (share-NIC) activity LED (green) |
| 2 System error LED (yellow) | 8 1 Gb RJ45 Ethernet port (share-NIC) link LED (green) |
| 3 Identification LED (blue) | 9 Drive activity LED (green) |
| 4 Dedicated XCC management connector (1 Gb RJ45) activity LED (green) | 10 25 Gb Ethernet port link and activity LED (port 2) (green) |
| 5 Dedicated XCC management connector (1 Gb RJ45) link LED (green) | 11 25 Gb Ethernet port link and activity LED (port 1) (green) |
| 6 Node power button with LED (green) |
1 RoT LED:
2 System error LED (yellow): When this yellow LED is lit, it indicates that a system error has occurred. Check the XCC event log for additional information.
3 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.
4 Dedicated XCC management connector (1 Gb RJ45) 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 Dedicated XCC management connector (1 Gb RJ45) link LED (green): Use this green LED to distinguish the network status.
- Off: The network link is disconnected.
- On: The network link is established.
- Off: Power is not present or the Power Conversion Station, 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 seconds.
- 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.
7 1 Gb RJ45 Ethernet port (share-NIC) 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.
8 1 Gb RJ45 Ethernet port (share-NIC) link LED (green): Use this green LED to distinguish the network status.
- Off: The network link is disconnected.
- On: The network link is established.
9 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.
10 11 25 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.
