5. Nastavitev

5.1 Montaža v stojalo

1. Priložene nosilce za montažo v rack pritrdite na stranice stikala s priloženimi vijaki.
2. Secure the switch into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate clearance for airflow.

5.2 Napajalni priključek

1. Connect the power cord to the AC power receptacle on the rear of the switch.
2. Drugi konec napajalnega kabla priključite v ozemljeno električno vtičnico.
3. Ensure the power supply is properly seated and secured.

5.3 Omrežne povezave

• 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 Začetna konfiguracija

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. Upravljanje stikala

6.1 Vklop/izklop

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 indikatorji

Spremljajte LED indikatorje na sprednji plošči, da boste razumeli stanje delovanja stikala:

• Sistemska 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 lučke za stanje vrat: Indicate link status and activity for each network port (e.g., green for link, blinking for activity).

6.3 Povezovanje naprav
