5. Opset en ynstallaasje

5.1 Site Tarieding

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

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

5.2 Rack Mounting

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