- Ensure power sources match the switch's input voltagالمتطلبات.
- Connect both power supplies for redundant operation.
2.4 اتصالات الشبكة
The DCS-7050S-52-R features 52 منافذ SFP+. Insert compatible SFP+ transceivers into the desired ports. Connect appropriate fiber optic or direct attach copper (DAC) cables to the transceivers. Ensure proper cable management to avoid strain on the ports.
2.5 التشغيل الأولي
After all physical connections are made, power on the switch. Observe the system status LEDs for initial boot-up sequence. Refer to the LED indicators section for status interpretation.
3. تعليمات التشغيل
3.1 تشغيل/إيقاف التشغيل
To power on, ensure power cords are connected. The switch will automatically power on. To power off, disconnect both power cords from their sources. For graceful shutdown, it is recommended to use the operating system commands before disconnecting power.
3.2 Management Interface Access
The switch can be managed via a console port (RJ-45), out-of-band management (OOB) Ethernet port, or in-band management through one of the SFP+ data ports. Connect a console cable to the console port and use a terminal emulator (e.g., PuTTY, Tera Term) with settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
3.3 Arista EOS Overview
The Arista DCS-7050S-52-R runs Arista EOS (Extensible Operating System). EOS provides a command-line interface (CLI) for configuration and monitoring. For detailed configuration instructions, refer to the official Arista EOS documentation available on the Arista Networks webموقع.
3.4 SFP+ Port Operation
The 52 SFP+ ports support 10 Gigabit Ethernet connectivity. Ensure that compatible SFP+ transceivers are used for the desired link type (e.g., SR, LR, DAC). Port status LEDs indicate link activity and speed.
4. الصيانة
4.1 التنظيف

- نظام الصمام: يشير إلى الحالة الصحية العامة للنظام (على سبيل المثال، اللون الأخضر للحالة الطبيعية، واللون الكهرماني للتحذير، واللون الأحمر للحالة الحرجة).
- مؤشرات LED لمصدر الطاقة: Indicate the status of each power supply.
- Fan LEDs: Indicate the status of the fan trays.
- مصابيح LED للمنفذ: Indicate link status and activity for each SFP+ port.
Refer to the Arista Networks documentation for a detailed explanation of all LED states.
5.2 المشكلات الشائعة
- لا يوجد طاقة: Verify power cord connections, power source, and power supply LEDs.
- لا يوجد رابط على المنفذ: Check transceiver compatibility, cable integrity, and connection to the peer device. Verify port configuration.
- عطل في النظام: Check system LED. If red, consult logs via console or management interface.
5.3 إجراءات إعادة الضبط
A system reboot can often resolve minor issues. Use the appropriate EOS command for a graceful reboot. In cases where the system is unresponsive, a hard power cycle (disconnecting and reconnecting power) may be necessary, but this should be a last resort.
