3.5 초기 구성

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 인터페이스 구성 단계.

4. 스위치 작동

4.1 전원 켜기/끄기

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 LED 표시등

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

• 시스템 LED: Indicates overall system status (e.g., power, boot status).
• 포트 LED: 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.

4.3 포트 기능

The EX2200-48P-4G provides 48 Gigabit Ethernet ports with Power over Ethernet (PoE) capabilities, allowing you to power compatible devices such as IP phones, wireless access points, and surveillance cameras directly through the network cable. The 4 SFP (Small Form-Factor Pluggable) uplink ports support fiber optic or copper connections for high-speed data transmission to other network devices or the core network.

4.4 관리 인터페이스

The switch can be managed through several interfaces:

• 명령줄 인터페이스(CLI): Accessible via the console port or SSH/Telnet for advanced configuration and monitoring.
• Web-Based Interface (Web 사용자 인터페이스): Provides a graphical interface for easier management and monitoring, accessible via a web 브라우저.
• SNMP: Supports Simple Network Management Protocol for integration with network management systems.
