3.5 Cấu hình ban đầu

For initial configuration, connect a console cable to the console port on the switch and to a computer. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control. Refer to the Juniper Networks documentation for detailed CLI or web interface configuration steps.

4. Vận hành công tắc

4.1 Bật / Tắt nguồn

To power on the switch, flip the power switch on the rear panel to the ON position. The system will initiate its boot sequence. To power off, flip the power switch to the OFF position. For controlled shutdowns, it is recommended to use the appropriate command-line interface (CLI) or web interface commands to prevent data corruption.

4.2 Đèn báo LED

The front panel features various LED indicators that provide status information for the system and individual ports.

• Hệ thống đèn LED: Indicates overall system status (e.g., power, boot status).
• Đèn LED cổng: Each Ethernet port has LEDs to indicate link status, activity, and PoE status. Refer to the detailed product documentation for specific LED behavior.
• SFP LEDs: Indicate link status and activity for the SFP uplink ports.
