2. CONSOLE: Connects to a maintenance terminal for AP configuration and management

3. GE/PoE_IN: 10M/100M/1,000M port that connects to the wired Ethernet and supports PoE input

4. DC 12V: Connects a 12V power adapter to the AP

LED indicators

Note: The indicator is located inside the panel, which turns on after the AP is powered on.

Indicator colors may vary slightly at different temperatures.

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.

The system enters the Uboot CLI.

Blinking once every 5s (0.2 Hz) The system is running properly, the Ethernet connection is normal, and no STA is associated with the AP. The system is in low-power consumption state.
Alarm Green Blinking once every 0.25s (4 Hz)

The software is being upgraded.

After the software is uploaded and started, the AP is working in Fit AP mode and requests to go online on the AC and maintains this state until it goes online successfully on the AC (before the CAPWAP link is established).

The AP working in Fit AP mode fails to go online on the AC (the CAPWAP link disconnects).

Fault Red Steady on A fault that affects services has occurred, such as a DRAM detection failure or system software load failure. The fault cannot be automatically rectified and must be rectified manually

Networking and applications

Fit AP networking (AP mode)

In this networking scenario, the AP functions as a Fit AP. The AC is responsible for user access, AP go-online, AP management, authentication, routing, security, and QoS. Huawei products that provide the AC function include the AC6605, AC6005, ACU2 (with S7700, S9700, or S12700), S5720HI, S7700 (with X series board), S9700 (with X series board), and S12700 (with X series board).

Fit AP networking (WDS mode: Point-to-Point)

Fit AP networking (WDS mode: Point-to-Multipoint)

In this networking scenario, the AP connects two or more independently wired or wireless LANs through wireless links to construct a network on which users can exchange data. In Wireless Distribution System (WDS) mode, the AP supports Point-to-Point (P2P) and Point-to-Multipoint (P2MP) networking modes. Supporting 5 GHz and 2.4 GHz frequency bands, the AP can implement wireless bridging and access functions.

Fit AP mesh networking

In this networking scenario, APs function as Mesh Points (MPs) and are fully meshed to establish an auto-configured and self-healing Wireless Mesh Network (WMN). APs with the gateway function can work as the Mesh Portal Points (MPPs) through which the WMN can provide access to the Internet. Terminals connect to APs to access the WMN. The WMN uses dedicated mesh routing protocols to guarantee high transmission quality and is more applicable to scenarios that require high bandwidth and highly stable Internet connections.

Fat AP networking

In this networking scenario, the device functions as a Fat AP to implement functions such as user access, authentication, data security, service forwarding, and QoS.
