3. Configuració i instal·lació

3.1 Unpacking the Controller

Carefully unpack the Cisco 5508 WLC from its shipping container. Verify that all components listed in the packing list are present and undamaged. Retain the packaging materials for future transport or storage.

3.2 Instal·lació física

The Cisco 5508 WLC is designed for rack mounting. Ensure adequate ventilation around the unit. Follow these steps for installation:

1. Mount the controller securely in a standard 19-inch equipment rack using the provided rack-mount kit.
2. Ensure proper grounding of the rack and the controller.
3. Connect the power cord to the controller's power input and then to a grounded AC power outlet.

3.3 Connexions de xarxa

Connect the necessary network cables to the controller's rear panel ports:

• Ports Gigabit Ethernet: Connect to your network switch infrastructure. These ports handle data traffic from access points and client devices.
• Port de gestió: Use this dedicated port for out-of-band management access.
• Port de la consola: Connect a serial cable from a management workstation to this port for initial configuration and command-line interface (CLI) access.
• Ports USB: For future use or specific accessory connections.

4. Funcionament del controlador

4.1 Configuració inicial

After physical installation and power-up, the controller requires initial configuration. This is typically done via the console port using a terminal emulator (e.g., PuTTY, Tera Term) with the following settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.

Follow the on-screen prompts to set up basic network parameters, administrator credentials, and management interfaces.

4.2 Management Interfaces

• Command-Line Interface (CLI): Accessible via the console port or SSH/Telnet. Provides full control over the controller's functions.
• Interfície gràfica d'usuari (GUI): Accessible via a web browser. Provides an intuitive interface for configuration, monitoring, and troubleshooting. Navigate to the controller's IP address in your web navegador.

4.3 Access Point Management

The Cisco 5508 WLC automatically discovers and manages Cisco Access Points (APs). Once an AP connects to the network and discovers the controller, it will download its configuration and begin serving wireless clients. Ensure proper network connectivity and firewall rules to allow APs to communicate with the controller.

5. Manteniment

5.1 actualitzacions de microprogramari

Consulteu regularment el suport tècnic de Cisco website for the latest firmware versions. Firmware updates provide new features, bug fixes, and security enhancements. Follow the official Cisco documentation for the correct firmware upgrade procedure to avoid service interruptions.

5.2 Còpia de seguretat i restauració de la configuració

It is critical to regularly back up your controller's configuration. This allows for quick recovery in case of a system failure or misconfiguration. Configuration files can typically be backed up to an external TFTP, FTP, or SFTP server.

5.3 Consideracions ambientals

Maintain the operating environment within specified temperature and humidity ranges to ensure optimal performance and longevity of the device. Ensure proper airflow and keep ventilation openings clear of obstructions.

6. Solució De Problemes

6.1 Problemes comuns

• Sense energia: Verify power cord connection, power outlet, and power supply status. Check power LED indicators.
• Connectivitat de xarxa: Ensure Ethernet cables are properly connected and network switches are operational. Check port status LEDs.
• Access Points Not Registering: Verify network reachability between APs and the controller, check firewall rules, and ensure correct controller discovery methods are configured on the APs.
• Problemes d'inici de sessió: Confirm correct username and password. If forgotten, refer to Cisco documentation for password recovery procedures.

6.2 Indicadors LED

Refer to the controller's front panel LEDs for quick status checks. Common LEDs include Power, System Status, and Port Status. Consult the Cisco 5500 Series documentation for a detailed explanation of each LED's behavior.

6.3 Passos bàsics de diagnòstic

1. Comproveu les connexions físiques.
2. Verify power and system status LEDs.
3. Ping the controller's IP address from a management workstation.
4. Access the CLI via console and check system logs for error messages.
