5. Поставување

5.1 Монтирање на решетка

1. Прикачете ги испорачаните држачи за монтирање на решетка на страните од прекинувачот користејќи ги испорачаните завртки.
2. Secure the switch into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate clearance for airflow.

5.2 Поврзување за напојување

1. Connect the power cord to the AC power receptacle on the rear of the switch.
2. Приклучете го другиот крај на кабелот за напојување во заземјен електричен штекер.
3. Ensure the power supply is properly seated and secured.

5.3 Мрежни врски

• Connect Ethernet cables from your network devices (computers, access points, IP phones) to the 48 Gigabit Ethernet ports on the front panel.
• For uplink connectivity, install the appropriate uplink module (if not pre-installed) and connect fiber or copper cables to your core network or other switches.
• For stacking, connect StackWise-480 cables between the stack ports of multiple Catalyst 9300 switches.

5.4 Почетна конфигурација

1. Connect a computer to the console port using the provided console cable.
2. Use a terminal emulation program (e.g., PuTTY, Tera Term) with settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
3. Power on the switch. The boot process will display messages on the console.
4. Follow the on-screen prompts to perform initial setup, including setting the hostname, IP address, and administrative passwords.

6. Ракување со прекинувачот

6.1 Вклучување/исклучување

To power on the switch, ensure the power cord is securely connected to a live outlet. The switch will automatically begin its boot sequence. To power off, disconnect the power cord. For graceful shutdown, use the appropriate command-line interface (CLI) commands.

6.2 LED индикатори

Monitor the LED indicators on the front panel to understand the switch's operational status:

• Системски LED: Indicates overall system health (e.g., green for normal, amber for warning, red for critical).
• PoE LED: Shows the status of Power over Ethernet (e.g., green for active PoE, amber for fault).
• LED диоди за статус на порта: Indicate link status and activity for each network port (e.g., green for link, blinking for activity).

6.3 Поврзување на уреди
