This topic provides information on LEDs of compute tray.
Figure 1. Compute tray LEDs
Table 1. Compute tray LEDs| 1 Power button/LED | 2 System ID button/LED |
| 3 NVLink status LED | 4 System fault LED |
| 5 OSFP port LED | 6 E1.S drive status LED |
| 7 E1.S drive activity LED | |
Press this button to turn the system on and off manually. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Off | None | The system is off. |
| Blinking (1 HZ) | Green | The system is in power-off state. |
| Blinking (4 HZ) | Green | The system is running POST. |
| Solid on | Green | The system is on and running. |
Use this system ID button and the system ID LED to visually locate the system. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Off | None | The system is in a normal operating state. |
| Blinking (1 HZ) | Blue | The location identification feature is activated. |
Use this NVLink status LED to monitor the NVLink connection status. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Off | None | The link is down. |
| Blinking (1 HZ) | Amber | Beaconing (locating) is active on any one of the NVLink ports. |
| Solid on | Amber | The physical link is established. |
| Blinking (1 HZ) | Green | The logical link is established and active. |
| Solid on | Green | The logical link is established with no active traffic. |
The system fault LED helps you to determine if there are any system errors. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Off | None | The system is working correctly. |
| Blinking (4 HZ) | Amber | A critical event has been detected. |
| Solid on | Amber | A non-recoverable event has been detected. |
Use the bi-color LED to monitor the activity of the OSFP card. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Blinking (4 HZ) | Green | The link is operating at the maximum supported speed. |
| Blinking (2 HZ) | Green | The link is operating below the maximum supported speed. |
| Solid on | Green | The link is active. |
| Blinking (4 HZ) | Yellow | An error has occurred to the link. |
| Blinking (1 HZ) | Yellow | The beacon command is used to locate the OSFP card. |
| Solid on | Yellow | A physical link is established in InfiniBand mode. This status is not applicable in Ethernet mode. |
Using command to light up locating LED is available when transceiver or cable is attached to the OSFP port.
Use the bi-color LED to monitor the status of the E1.S drive. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Off | None | The drive is not present or power is unavailable. |
| Solid on | Blue | The drive is operating normally. |
| Solid on | Amber | A drive failure has been detected. |
Use the bi-color LED to monitor the activity of the E1.S drive. The states of the LED are as follows:
| Status | Color | Description |
|---|
| Off | None | The drive is not present or power is disconnected. |
| Blinking (4 HZ) | Green | Drive activity is in progress; removal is allowed. |
| Solid on | Green | The drive is powered and active; removal is allowed. |
| Blinking (4 HZ) | White | Drive activity is in progress; removal is not allowed. |
| Solid on | White | The drive is powered and active; removal is not allowed. |
