1 2 RJ45 management port status LEDs​

The RJ45 management port is a 1Gb Ethernet port that has two status LEDs.
Status LEDStatusColorDescription
1 RJ45 management port link LEDOnGreenA link is established between the port and some upstream device.
OffNoneNo link is established.
2 RJ45 management port activity LEDBlinkingGreenTraffic is flowing over the connection.
OffNoneNo traffic is flowing over the connection.

3 NVMEM discharge LED​

The NVMEM discharge LED provides the status of ONTAP running on the controller.
StatusColorDescription
BlinkingGreenNVMEM destage events are occurring.
SolidGreenNVMEM destage events completed successfully.
OffNoneThe system is running normally and the NVMEM is ready if ONTAP is running.

4 Controller location LED​

The controller location LED is a blue LED that helps to show the location of a specific controller in a system.

5 Controller attention LED​

The controller attention LED indicates that there is an issue with a controller. Check other LEDs and event logs to determine the cause of the issue.
StatusColorDescription
OnAmberThe controller has a fault.
OffNoneThe controller is operating normally.

6 Controller activity LED​

The controller activity LED provides the status of ONTAP running on the controller.
StatusColorDescription
BlinkingGreenThe controller is running ONTAP. The length of time the light remains on is proportional to the controller activity.
OffNoneONTAP is not running on the controller.
