2.3 Pradinė konfigūracija

• Connect a console cable (RJ45) from your management workstation to the console port on the controller's front panel.
• Use a terminal emulation program (e.g., PuTTY, Tera Term) to access the command-line interface (CLI).
• Follow the on-screen prompts to perform initial setup, including setting up management IP addresses, subnet masks, and default gateways.

3. Naudojimo instrukcijos

3.1 Įjungimas / išjungimas

• To power on, ensure all power cables are securely connected and then flip the power switches on the rear power supply units to the 'ON' position.
• Observe the front panel LEDs (PS1, PS2, SYS, ALM) to monitor the boot process and operational status.
• To power off, gracefully shut down the system via the management interface if possible, then flip the power switches to the 'OFF' position and disconnect power cables.

3.2 Connecting Access Points

The Cisco 5508 controller automatically discovers and manages Cisco Aironet Access Points. Once connected to the network, access points will attempt to join the controller.

• Ensure access points are powered on and connected to the network where the controller is accessible.
• Configure appropriate network settings (VLANs, DHCP) to allow APs to discover and communicate with the controller.

3.3 Pagrindinis tinklo valdymas

The controller can be managed via a web-based graphical user interface (GUI) or the command-line interface (CLI).

• Prisijunkite prie web GUI by entering the controller's management IP address into a web naršyklė.
• Use the GUI for common tasks such as monitoring network status, configuring WLANs, managing access points, and viewing client information.
• The CLI provides advanced configuration options and is accessible via the console port or SSH/Telnet.

4. Priežiūra

4.1 Reguliarūs patikrinimai

• Periodically check the environmental conditions (temperature, humidity) of the installation site. The operating temperature should not exceed 40 degrees Celsius.
• Verify that all network and power cables are securely connected.
• Monitor the status LEDs on the front panel for any abnormal indications (e.g., Alarm LED).

4.2 Firmware atnaujinimai

Reguliariai tikrinkite „Cisco“ palaikymo tarnybą website for the latest firmware updates. Keeping the controller's firmware up-to-date ensures optimal performance, security, and access to new features.

• Download firmware images only from official Cisco sources.
• Follow the specific upgrade procedures outlined in the release notes for each firmware version.

4.3 Valymas

• Ensure the controller is powered off and disconnected from power before cleaning.
• Išoriniams paviršiams valyti naudokite minkštą, sausą šluostę.
• Use compressed air to gently clear dust from ventilation grilles and fan openings to maintain proper airflow.

5. Problemų sprendimas

5.1 Bendrosios problemos ir sprendimai

• Nėra galios: Check power cable connections to the controller and the power outlet. Verify that the power supply LEDs on the rear are illuminated.
• Nėra tinklo ryšio: Ensure Ethernet cables are properly connected to the correct ports. Check the link/activity LEDs on the front panel ports. Verify IP configuration.
• Access Points Not Joining: Confirm that APs can reach the controller's management IP address. Check firewall rules and ensure proper DHCP/DNS configuration for AP discovery.

5.2 LED Status Indicators (Front Panel)

• PS1/PS2 (Power Supply): Indicates the status of the respective power supply unit. Typically green for operational.
• SYS (Sistema): Indicates the overall system status. Green for normal operation, amber/red for warnings or faults.
• ALM (signalizacija): Illuminates to indicate a system alarm or critical event. Refer to system logs for details.
