R250D indicator status description
| Information type | colour | Indicator status | Express meaning |
| Power-on default state | green | Chang Liang | The device has just been powered on, but the software has not started. |
| Software startup process status | green | Always on after blinking | When the system reset is completed and the software starts to start, the green light flashes once, and then the green light remains on until the system is started. |
| run | green | Slow flashing（0.5Hz） | The system is operating normally, the Ethernet connection is normal, and there is user association. |
| Slow flashing（0.2Hz） | The system is operating normally, the Ethernet connection is normal, there is no user association, and the system is in a low power consumption state. |
| Alert | green | Flash（4Hz） | - During the software upgrade
- After the software is loaded and started, it enters the request to go online state. Go online successfully（CAPWAP chain establishment）Have been in this state before
- Failed to go online（CAPWAP broken link）
|
| malfunction | red | Chang Liang | The equipment has a fault that affects the business and cannot be recovered by itself（If the DRAM test fails, the software system fails to load）, Requires manual intervention. |
