1 2 RJ45 management port status LEDs
The RJ45 management port is a 1Gb Ethernet port that has two status LEDs.
Status LED | Status | Color | Description |
---|---|---|---|
1 RJ45 management port link LED | On | Green | A link is established between the port and some upstream device. |
Off | None | No link is established. | |
2 RJ45 management port activity LED | Blinking | Green | Traffic is flowing over the connection. |
Off | None | No traffic is flowing over the connection. |
3 NVMEM discharge LED
The NVMEM discharge LED provides the status of ONTAP running on the controller.
Status | Color | Description |
---|---|---|
Blinking | Green | NVMEM destage events are occurring. |
Solid | Green | NVMEM destage events completed successfully. |
Off | None | The 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.
Status | Color | Description |
---|---|---|
On | Amber | The controller has a fault. |
Off | None | The controller is operating normally. |
6 Controller activity LED
The controller activity LED provides the status of ONTAP running on the controller.
Status | Color | Description |
---|---|---|
Blinking | Green | The controller is running ONTAP. The length of time the light remains on is proportional to the controller activity. |
Off | None | ONTAP is not running on the controller. |
