### OS Failure
|
|
|

Verify whether [System Activity LED](/helios64/front-panel/#helios64-enclosure) is blinking. If it is not, reset or power cycle.

|
|
|
If problem still occurs, please capture the serial console output and report it to forum.

|
If [System Error LED](/helios64/front-panel/#helios64-enclosure) blinking, there was kernel panic.

|
```
