5. Setup u Installazzjoni

5.1 Preparazzjoni tas-Sit

Before installation, ensure the installation site meets the following requirements:

• Ambjent: Maintain an ambient temperature between 0°C and 45°C (32°F and 113°F) and relative humidity between 10% and 85% (non-condensing).
• Qawwa: A dedicated power outlet with proper grounding is recommended.
• Ventilazzjoni: Ensure at least 5 cm (2 inches) of clearance at the front and rear for airflow.

5.2 Immuntar fuq Rack

The EX4200-24P is designed for installation in a standard 19-inch equipment rack.

1. Attach the provided rack-mount brackets to the sides of the switch using the supplied screws.
2. Align the switch with the rack posts and secure it using appropriate rack screws.

5.3 Konnessjoni tal-Enerġija

1. Connect one end of the power cord to the AC power connector on the rear panel of the switch.
2. Qabbad it-tarf l-ieħor tal-korda tal-enerġija ma' sokit elettriku ertjat.
3. The switch will power on automatically. Observe the system status LEDs for initial boot-up.

5.4 Konnessjonijiet tan-Netwerk

1. Connect Ethernet cables from your network devices (computers, IP phones, wireless access points) to the RJ-45 ports on the front panel.
2. For uplink connections to other switches or routers, insert appropriate SFP/SFP+ transceivers into the uplink module slot and connect fiber or copper cables as required.
