5. Setup u Installazzjoni

5.1 Preparazzjoni tas-Sit

• Kun żgur li s-sit tal-installazzjoni jkun nadif, niexef u ventilat sew.
• Maintain an ambient temperature between 0°C and 45°C (32°F and 113°F).
• Ensure proper grounding is available at the installation site.

5.2 Immuntar fuq Rack

1. Waħħal il-parentesi tal-immuntar tar-rack provduti mal-ġnub tas-swiċċ billi tuża l-viti inklużi.
2. Align the switch with the rack posts and secure it using appropriate rack screws. Ensure the switch is level and stable.

5.3 Konnessjoni tal-Enerġija

1. Qabbad il-korda tal-enerġija AC mad-daħla tal-enerġija fuq il-pannell ta' wara tas-swiċċ.
2. Ipplaggja t-tarf l-ieħor tal-korda tad-dawl fi żbokk elettriku ertjat.
3. The power LED on the front panel should illuminate, indicating the switch is receiving power.

5.4 Konnessjoni tan-Netwerk

1. Connect Ethernet cables from your network devices (computers, servers, other switches) to the 10/100/1000BASE-T ports on the front panel.
2. For uplink connections to your core network, insert SFP/SFP+ transceivers (if applicable) into the uplink ports and connect appropriate fiber or copper cables.
3. Observe the port status LEDs to confirm link establishment and activity.

5.5 Initial Configuration (Console Access)

1. Connect the console cable (RJ-45 to DB-9) from the switch's console port to a serial port on a computer.
2. Configure your terminal emulation software (e.g., PuTTY, Tera Term) with the following settings:
   • Rata Baud: 9600
   • Bits tad-Data: 8
   • Parità: Xejn
   • Waqqaf Bits: 1
   • Kontroll tal-Fluss: Xejn
3. Power on the switch. You should see boot messages in the terminal window.
4. Follow the on-screen prompts to perform initial configuration, including setting up management IP addresses and basic network parameters.

6. Tħaddim tas-Swiċċ

6.1 Power On/Off

To power on the switch, connect the power cord to a live electrical outlet. To power off, disconnect the power cord. It is recommended to gracefully shut down the switch via the command-line interface (CLI) if possible before disconnecting power to prevent data corruption or configuration loss.

6.2 Indikaturi LED

L-LEDs tal-pannell ta' quddiem jipprovdu status viżwali tal-operazzjoni tas-swiċċ:

• LED SYS: Indicates system status (e.g., green for normal operation, amber for fault).
• LED PWR: Indicates power status (e.g., green for power on).
• LEDs tal-port: Each port has LEDs indicating link status (on/off) and activity (blinking). Refer to the Juniper Networks documentation for specific LED behavior.

6.3 Ġestjoni Bażika

After initial configuration, the switch can be managed via the CLI (Command Line Interface) through the console port, Telnet, or SSH. A web-based graphical user interface (GUI) may also be available depending on the Junos OS version. Refer to the Juniper Networks Junos OS documentation for detailed management instructions.

7. Manutenzjoni

7.1 Tindif
