2. Log in using default credentials (refer to Juniper documentation for specific default credentials for Junos OS).
3. Configure basic network settings, including IP address, subnet mask, and default gateway, to enable remote management.

4.2 Indikaturi LED

• LED tal-qawwa: Jindika l-istatus tal-qawwa tas-swiċċ.
• LED tal-Istatus: Provides general system health information.
• LEDs tal-port: Indika l-istatus u l-attività tal-link għal kull port tan-netwerk.

Refer to the official Juniper Networks documentation for detailed information on LED behavior and advanced Junos OS configuration.

5. Manutenzjoni

Regular maintenance ensures optimal performance and longevity of your switch.

5.1 Fluss tal-Arja u Tkessiħ

• The QFX5100-48S-AFI uses a back-to-front airflow system. Ensure that the air intake (rear) and exhaust (front) are not obstructed.
• Periodically inspect the fan modules for dust accumulation. Clean as necessary using compressed air.
• Fan modules are hot-swappable; if a fan fails, replace it promptly without powering down the switch.

5.2 Power Supply Units (PSUs)

• The switch is equipped with dual hot-swappable PSUs for redundancy.
• In case of a PSU failure, replace the faulty unit immediately to maintain power redundancy.

5.3 Tindif Ġenerali

• Keep the exterior of the switch clean and free of dust. Use a soft, dry cloth.
• Do not use liquid cleaners directly on the switch.
