3. Содержимое упаковки

Проверьте наличие всех предметов в упаковке:

• 1 x NVIDIA Spectrum-2 MSN3700C Ethernet Switch
• 2 x Power Supplies (AC)
• 1 x Rail Kit

4. Настройка

4.1. Физическая установка

The MSN3700C switch is designed for rail mounting, suitable for standard server racks.

1. Attach the provided rail kit to the server rack according to the rail kit instructions.
2. Carefully slide the switch onto the installed rails until it clicks into place.
3. Secure the switch to the rack using the appropriate screws.

4.2. Подключение питания

Connect the two AC power supplies to the switch and then to a grounded power source.

• Insert each power supply unit into its designated slot on the switch.
• Connect the power cables from the power supply units to separate, grounded AC outlets for redundancy.
• Verify that the power indicator LEDs on the switch illuminate.

4.3. Сетевые подключения

The switch features 32 SFP+ ports for 100 Gigabit Ethernet connectivity.

• Insert compatible SFP+ transceivers into the desired ports.
• Connect optical fiber cables from the transceivers to your network devices (servers, other switches).
• The ports can be split to support up to 128x 10/25GbE ports using appropriate splitter cables and transceivers.

5. Инструкция по эксплуатации

5.1. Базовая функциональность

The MSN3700C supports comprehensive Layer-2 and Layer-3 switching capabilities.

• Layer-2 Switching: Facilitates efficient data forwarding within a local network segment.
• Layer-3 Switching: Enables routing between different network segments and subnets.

5.2. Расширенные функции

The switch incorporates advanced features for modern data center networking:

• RoCE Transport: Robust support for RDMA over Converged Ethernet, powering NVMe over Fabric and Machine Learning applications leveraging NVIDIA GPUDirect.
• VXLAN: Best-in-class VXLAN scale for network virtualization, supporting high-performance single-pass VXLAN routing.
• Network Telemetry: Features like NVIDIA What Just Happened (WJH) telemetry, hardware-accelerated histograms, and Inband Network Telemetry (INT)-ready hardware provide deep visibility into network performance and dramatically reduce mean time to issue resolution.
• Programmable Pipeline: Allows programmatic parsing, processing, and editing of packets for flexible network operations.

6. Техническое обслуживание

6.1. Условия окружающей среды

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

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

6.2. Уборка

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

• Для очистки используйте мягкую сухую ткань.
• Не используйте жидкие чистящие средства или аэрозоли непосредственно на устройстве.
• Перед началом чистки убедитесь, что питание отключено.

7. Поиск Неисправностей

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

• Нет питания: 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.
• Проблемы с производительностью: Utilize the switch's telemetry features (WJH, histograms) to diagnose network congestion or packet loss. Consult network configuration.
• Доступ к настройкам: Ensure management interfaces are correctly configured and accessible.
