5.1 Rack arịọnụ

1. Attach the provided rack-mount brackets to the sides of the switch using the included screws.
2. Secure the switch into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate clearance for airflow.

5.2 Njikọ ike

1. Connect the power cord to the AC power receptacle on the rear of the switch.
2. Tinye nsọtụ nke ọzọ nke eriri ọkụ n'ime oghere eletrik gbadoro ụkwụ.
3. Ensure the power supply is properly seated and secured.

5.3 Njikọ netwọkụ

• 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 Nhazi izizi

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. Na-arụ ọrụ mgba ọkụ

6.1 Gbanyụọ ma ọ bụ gbanyụọ

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 egosi

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

• Sistemu 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).
• Igwe ọkụ Ọdụdọ Port: Indicate link status and activity for each network port (e.g., green for link, blinking for activity).

6.3 Ngwa jikọọ

Connect network devices to the Gigabit Ethernet ports. For devices requiring power, ensure they are PoE-compatible and the switch's PoE budget is sufficient. The switch automatically detects and provides power to PoE-enabled devices.
