• Programmable Pipeline: Allows programmatic parsing, processing, and editing of packets for flexible network operations.

6. الصيانة

6.1. الظروف البيئية

Maintain the operating environment within specified limits to ensure optimal performance and longevity.

• درجة حرارة: Do not exceed 60 Degrees Celsius. Ensure adequate airflow.
• رطوبة: Keep within recommended non-condensing humidity levels.

6.2. التنظيف

Periodically clean the exterior of the switch and ensure ventilation openings are free from dust and debris.

• استخدم قطعة قماش ناعمة وجافة للتنظيف.
• لا تستخدم المنظفات السائلة أو البخاخات مباشرة على الجهاز.
• تأكد من فصل التيار الكهربائي قبل التنظيف.

7. استكشاف الأخطاء وإصلاحها

If you encounter issues with your NVIDIA Spectrum-2 MSN3700C Ethernet Switch, consider the following basic troubleshooting steps:

• لا يوجد طاقة: Verify power cable connections and ensure power outlets are functional. Check power supply unit status LEDs.
• Link Issues: Confirm SFP+ transceivers are correctly seated and optical fiber cables are undamaged and properly connected. Check link status LEDs on the switch and connected devices.
• مشاكل الأداء: Utilize the switch's telemetry features (WJH, histograms) to diagnose network congestion or packet loss. Consult network configuration.
• الوصول إلى الإعدادات: Ensure management interfaces are correctly configured and accessible.
