LED Indicators
| Type | Color | Status | Description |
|---|---|---|---|
| Default Status after Power-on | Green | Steady on | The AP is just powered on and the software is not started yet. |
| Software Startup Status | Green | Steady on after blinking once | After the system is reset and starts uploading the software, the indicator blinks green once. Until the software is uploaded and started, the indicator remains steady green. |
| Running Status | Green | Blinking once every 2s (0.5 Hz) |
The system is running properly, the Ethernet connection is normal, and STAs are associated with the AP. |
| Blinking once every 5s (0.2 Hz) | The system is running properly, the Ethernet connection is normal, and STAs are associated with the AP. | ||
| Alarm | Green | Blinking once Alarm Green every 0.25s (4 Hz) |
The software is being upgraded. |
| Fault | Red | Steady on | A fault that affects services has occurred, such as a DRAM detection failure or system software loading failure. The fault cannot be automatically rectified and must be rectified manually. |

Networking and applications
On the network shown in the figure, RUs provide high-power radio signals and can be mounted on a ceiling or wall, or embedded into an 86-type box. A central AP connects to the RUs through network cables and provides PoE power for them. In addition, the central AP manages the RUs and processes services. It can be deployed in the ELV room and connects to more RUs through a PoE switch.
