| 
 | 
 | place or its rotation is obstructed. | 
| 
 | PWR1 | PWR1 failure LED. ON means PWR1 has failed. | 
| 
 | PWR2 | PWR2 failure LED. ON means PWR2 ahs failed. | 
| RESET | 
 | RPU hardware reset button. | 
| LINK (green) | OFF means the link is not connected and ON | |
| 
 | 
 | means the link is connected. |
