4.2 Conexión da enerxía e da rede

1. Colocación de antenas: Screw the external antennas onto the RP-TNC connectors on the access point. Ensure they are finger-tight.
2. Conectar a Ethernet: Connect an Ethernet cable from your network switch (preferably a Power over Ethernet (PoE) enabled switch) to the Ethernet port on the access point. If PoE is not used, connect the power adapter to the access point's power input and then to an electrical outlet.
3. Encendido: Once the network and power connections are secure, the access point will power on automatically. Observe the LED indicators for boot-up status.

4.3 Configuración inicial

As a Lightweight Access Point, the AIR-LAP1252AG-A-K9 requires a Cisco Wireless LAN Controller (WLC) for full operation and configuration. Upon boot-up, the access point will attempt to discover and join a WLC on the network. Refer to your WLC documentation for specific configuration steps, including:

• WLC discovery methods (DHCP, DNS, broadcast).
• Assigning the access point to a specific WLC.
• Configuring SSIDs, security settings, and radio parameters.

5. Funcionamento

5.1 Entender os indicadores LED

The access point features LED indicators that provide visual feedback on its operational status:

• LED de estado: Indicates the overall operational state (e.g., booting, associated with WLC, transmitting data). Refer to the official Cisco documentation for detailed LED patterns and their meanings.
• LED de radio: Indicate activity on the 2.4 GHz and 5 GHz radios.

5.2 Configuración da rede sen fíos

All wireless network configurations, including SSID broadcasting, security protocols (WPA2/WPA3), VLAN tagging, and radio power settings, are managed centrally through the Cisco Wireless LAN Controller. Once the access point has joined the WLC, it will download its configuration and begin broadcasting the configured wireless networks.

6. Mantemento

6.1 Limpeza

To maintain optimal performance and extend the lifespan of your access point:

• Apagado: Desconecte sempre a alimentación antes de limpar.
• Exterior: Use a soft, dry, lint-free cloth to wipe the exterior surfaces. Do not use liquid cleaners, aerosols, or solvents.
• Ventilación: Periodically check ventilation openings for dust accumulation and gently clear them using compressed air if necessary.

6.2 Actualizacións de firmware

Firmware updates for the access point are managed and pushed by the Cisco Wireless LAN Controller. Ensure your WLC is running the latest recommended software version to provide the most stable and secure environment for your access points. Consult Cisco's official documentation for WLC firmware upgrade procedures.
