| 
 | RPU The RPU functions primarily to process protocols, forward  | 
| 
 | control interfaces, and detect faults. The state monitoring information, such as the | 
| 
 | operation states of FAN, PWR, and system can be shown directly via the LEDs on | 
| 
 | the RPU, or reported to the network management system. In addition, RPU also | 
| 
 | provides the hardware reset button, RESET. |
